Abstract: Environmental niche models are useful tools for generating hypotheses for the distribution of species and informing conservation planning, especially at the edge of species’ ranges and for those with limited data. Here we report on the recent documentation of four species of amphibian (Hylarana latouchii, Odorrana tianmuii, Polypedates braueri, and Zhangixalus dennysi) and one reptile (Protobothrops mucrosquamatus) with few or no previous geolocated records from Jiangsu, China. We combined our opportunistic field sampling data from Jiangsu, which is at the edge of each of these species’ ranges, with publicly available occurrence records and climatic data to generate environmental niche models for these five species using Maxent. All models showed good model performance with AUC values ranging from 0.899 to 0.983. Additional potentially suitable areas within southern Jiangsu were predicted for the four amphibian species, although the significant anthropogenic habitat modifications in the province may limit their contemporary distributions. For all five species, the climatic variable that contributed most to the model was the precipitation of the driest month (Bio 14), indicating they are limited by moisture availability. Our study adds new information about the climatic preferences of these five species and highlights the value of complementing environmental niche modeling with field surveys for robust inferences and conservation planning, particularly at the edge of species’ ranges.

Kleptoparasitism in Micrurus mipartitus (Squamata, Elapidae) competing for the same Caecilia sp. (Gymnophiona, Caeciliidae) in western Colombia https://herpetozoa.pensoft.net/article/112716/ Herpetozoa 37: 77-84

DOI: 10.3897/herpetozoa.37.e112716

Authors: Henrik Bringsøe, Niels Poul Dreyer

Abstract: Kleptoparasitism, or food theft, is seldom reported in wild populations of snakes. Here, we describe as case where two Red-tailed Coral Snakes, Micrurus mipartitus, were observed competing for the same caecilian prey, either Caecilia leucocephala or C. perdita. This took place at night in a rainforest habitat in Valle del Cauca Department, western Colombia. Upon our arrival, the battle had already started as the two coral snakes kept bite-holds on the caecilian. They continued biting the prey at different places on the anterior parts and tugging in opposite directions. The snakes also made rotations along the longitudinal axis as they maintained their bite-holds. Surprisingly, one snake also bit the body of the other snake once. After 17 minutes of observation, the losing coral snake released its bite-hold on the caecilian. The winner then moved away from the losing snake which did not follow. It is well-known that M. mipartitus and other coral snakes eat caecilians, but this is the first observation of kleptoparasitism in elapid snakes in the wild. It is considered likely that they rely on chemoreception when detecting caecilians, notably in this case as two coral snakes detected the same prey item. In general, kleptoparasitism may occur more frequently amongst snakes than indicated by the very few published cases considering that numerous cases from captivity are known.

The first record of the rarely observed rat snake, Elaphe urartica Jablonski et al., 2019 (Squamata, Colubridae) for Iraq https://herpetozoa.pensoft.net/article/117207/ Herpetozoa 37: 73-76

DOI: 10.3897/herpetozoa.37.e117207

Authors: Daniel Jablonski, Soran H. Ahmed

Abstract: The Urartian rat snake, Elaphe urartica Jablonski, Kukushkin, Avcı, Bunyatova, Ilgaz, Tuniyev & Jandzik, 2019, is a recently described species within the genus Elaphe, found in eastern Anatolia, Caucasian region and the northern Middle East. It stands as one of the rarely observed snake species, with its distribution and other aspects of natural history largely unexplored. This is particularly true for the territories of Iraq and Iran. Therefore, we report on the presence of the species in Iraq, the first documented evidence of the species’ distribution within the country. In conjunction with this record, we provide initial data regarding the species’ habitat and ecology in the region. The distribution record presented here is further supplemented by a new species record from the border regions between Iraq and Iran, encouraging further herpetological exploration within the Zagros Mountains.

First description of the female of Cyrtodactylus dianxiensis Liu & Rao, 2021, with extended diagnosis of this species (Squamata, Gekkonidae) https://herpetozoa.pensoft.net/article/119492/ Herpetozoa 37: 65-72

DOI: 10.3897/herpetozoa.37.e119492

Authors: Dongru Zhang, Yunhe Wu, Changsheng Zuo, Fawang Yin, Shuo Liu

Abstract: Cyrtodactylus dianxiensis Liu & Rao, 2021 was originally described based on only two adult male specimens from Tongbiguan Nature Reserve, Dehong Autonomous Prefecture, western Yunnan, China. So far, no information on the females of this species is available. During comprehensive herpetofaunal investigations in 2022, one female specimen of C. dianxiensis was collected from Tongbiguan Nature Reserve. The female specimen agrees well with the original description of C. dianxiensis, and also shows some slight differences in coloration. This study reported the female specimen of this species for the first time, and provided a description and photos of the female specimen; meanwhile, we extended the diagnosis of this species.

New data on the distribution of the Vipera ammodytes (Linnaeus, 1758) mitochondrial lineages place their contact zone in western Bulgaria https://herpetozoa.pensoft.net/article/116879/ Herpetozoa 37: 57-63

DOI: 10.3897/herpetozoa.37.e116879

Authors: Angel Dyugmedzhiev, Kostadin Andonov, Georgi Hristov, Simeon Borissov

Abstract: Molecular studies have outlined several mitochondrial lineages of Vipera ammodytes, but the limits of their distribution ranges remain unclear due to limited sampling throughout the vast range of the species. One particularly understudied area is the Eastern Balkan Peninsula where at least three lineages occur, showing ranges that may be partly overlapping. We used two mitochondrial markers (cytb and ND2) to unveil mtDNA distribution patterns based on vipers from 31 localities across Bulgaria. Our results confirmed the presence of the north-eastern (NE) and the south-eastern (SE) mitochondrial clade in Bulgaria, the latter being represented by its southern (S) and eastern (E) subclades. Among the sampled localities, two were suspected to be potential contact zones between these mtDNA lineages based on old morphology-derived distributional records. The NE clade was absent from both potential contact zones. However, our data showed that in western Bulgaria, populations of this clade establish contact with populations of the E subclade in at least one area, and also come close to contact with populations of the S subclade. These results indicate the need for more detailed research in the potential areas of contact in western Bulgaria, integrating morphological data with extensive mitochondrial and nuclear DNA-sampling to better understand the phylogeographic patterns of intraspecific differentiation in V. ammodytes.

Three brown frog species in Denmark have different abilities to colonise new ponds https://herpetozoa.pensoft.net/article/107986/ Herpetozoa 37: 43-55

DOI: 10.3897/herpetozoa.37.e107986

Authors: Kåre Fog

Abstract: For 29 consecutive years, the populations of three species of brown frogs, Rana arvalis, R. dalmatina and R. temporaria, were monitored in an open area in South Zealand, Denmark, with no direct influence of agriculture. Population sizes were recorded by counting egg clumps and showed large variations from year to year. The total population of R. arvalis differed by a factor of 100 between the years with the lowest and the highest numbers. A total of 19 initially unoccupied suitable waterbodies could potentially be colonised by the frogs. Rana dalmatina colonised all of the ponds, mostly in the very first year of existence. Rana arvalis colonised 17 ponds after an average of 10.5 years. Rana temporaria colonised eight ponds after an average of 13.4 years. Colonisation by R. dalmatina was independent of changes in total population size, whereas colonisation by R. arvalis predominantly occurred in years with considerable population increases. The results are discussed in relation to the movement patterns and philopatry of juvenile frogs of the three species. Juvenile R. dalmatina disperse far from the breeding site, but most individuals return to their natal site. This allows the species to be an efficient coloniser of new waterbodies and, at the same time, to have stable occurrence at the original site. The two other species show a more erratic type of dispersal and especially R. temporaria often shifts breeding site from year to year.

An updated checklist of the amphibians and reptiles of Nayarit, Mexico with conservation status and comparison with adjoining States https://herpetozoa.pensoft.net/article/112093/ Herpetozoa 37: 25-42

DOI: 10.3897/herpetozoa.37.e112093

Authors: Jesús A. Loc-Barragán, Geoffrey R. Smith, Guillermo A. Woolrich-Piña, Julio A. Lemos-Espinal

Abstract: Herein, we present an updated list of the species of amphibians and reptiles that inhabit Nayarit, Mexico. In the years since the publication of a previous list in 2016, threats to amphibians and reptiles in Nayarit have continued unabated and efforts to more fully catalogue the richness of Nayarit’s herpetofauna have continued. Nayarit harbours 162 native species of amphibians and reptiles, representing 35 families and 85 genera. These include 37 species of amphibians (35 anurans and two salamanders) and 125 species of reptiles (one crocodile, 44 lizards, 69 snakes and 11 turtles). Of the amphibian and reptile species in Nayarit, 102 are endemic to Mexico and two endemic to Nayarit. The ecoregion with the highest richness of amphibians and reptiles in Nayarit is the Trans-Mexican Volcanic Belt followed closely by the Sierra Madre Occidental and then the Sierra Madre del Sur, the Pacific Lowlands and the Nayarit Islands. Just 5.8% of the species of amphibians and reptiles in Nayarit is IUCN-listed as Vulnerable, Endangered or Critically Endangered, 11.1% are placed in a protected category by SEMARNAT and nearly a third are categorised as high risk by the Environmental Vulnerability Score. The herpetofauna of Nayarit overlaps the most with Jalisco (88.9%). One of the main conclusions of our updated list of the amphibian and reptile species of Nayarit is that our understanding of the full complement of species is not complete, especially the reptiles.

The validity of Rana bannanica Rao & Yang, 1997 (Anura, Ranidae) https://herpetozoa.pensoft.net/article/114263/ Herpetozoa 37: 11-20

DOI: 10.3897/herpetozoa.37.e114263

Authors: Shuo Liu, Tan Van Nguyen, Nikolay A. Poyarkov, Qiaoyan Wang, Dingqi Rao, Song Li

Abstract: One specimen of frog was collected from Mohan Town, Mengla County, Xishuangbanna Prefecture, Yunnan Province, China, which is the type locality of Rana bannanica Rao & Yang, 1997, currently considered as a junior synonym of Hylarana milleti (Smith, 1921). This specimen well agrees with the original description of R. bannanica. In regard to morphology, R. bannanica and H. milleti are, indeed, very similar, but can still be distinguished from each other. Phylogenetic analysis, based on mitochondrial gene sequences, showed that this specimen and H. milleti are different species. Hence, we remove R. bannanica from the synonymy of H. milleti.

Reproductive effort of Plestiodon copei (Squamata, Scincidae), a highland viviparous lizard from Central Mexico https://herpetozoa.pensoft.net/article/111749/ Herpetozoa 37: 1-10

DOI: 10.3897/herpetozoa.37.e111749

Authors: Hermilo Sánchez-Sánchez, Adriana Jocelyn Morales-Gonzaga, Ken Oyama, J. Carlos Alvarado-Avilés

Abstract: Female reproductive effort is defined as the proportion of total energy or resources devoted to reproduction. In reptiles, there is frequently high inter- and intra-population variation related to several factors, such as food availability, climatic conditions, age and size, all of which, in turn, also influence survival and future reproduction. The present study is the first reproductive effort analysis of a population of the high-mountain scincid lizard Plestiodon copei in central Mexico, focusing on relative litter mass (RLM), investment per capita (INV) and productivity (PROD). We also compared the reproductive efficacy of P. copei to those of other Mexican congeners. We collected 24 gravid females of P. copei over a 4-year period and recorded a total of 90 neonates born in captivity. We found significant variation in neonatal mass amongst individual females and across years. We recorded an average litter size of 3.75 and an average litter mass of 1.25 g, which were positively correlated with both the size and total mass of the reproductive females. The RLM, INV and PROD values (0.301, 0.428 g and 1.236 g × year-1, respectively) for P. copei were greater than those for other Mexican species in the P. brevirostris group (0.290, 0.412 g and 1.135 g × year-1), revealing that females of P. copei from Tenango invest a comparatively high amount of their resources in reproduction.

Migration strategy of the Great crested newt (Triturus cristatus) in an artificial pond https://herpetozoa.pensoft.net/article/112826/ Herpetozoa 36: 345-356

DOI: 10.3897/herpetozoa.36.e112826

Authors: Lukáš Weber, Jan Růžička, Ivan H. Tuf, Martin Rulík

Abstract: In animals, migration is an evolutionary adaptation to manage seasonally varying habitats. Often driven by climatic changes or resource availability, amphibians then migrate from their hibernation sites to their breeding grounds. This research focused on the migratory habits of the Great crested newt (Triturus cristatus). The study explored factors like gender, body size, and environmental determinants, noting that immigration and emigration events proved distinct during the year. Results unveiled that males typically reached ponds first, with temperature being pivotal: males preferred up to 5 °C, females around 10 °C, while juveniles moved as temperatures increase. Wind velocity affected larger newts, around 120 mm, prompting them to migrate with stronger winds. Notably, heavy rainfall favored migration of newts of roughly 60 mm size. Humidity displayed gender-based trends: males associated positively with average levels, females showed aversion above 50%, and juveniles leaned towards drier conditions. Emigration patterns mirrored these findings, emphasizing roles of temperature, wind, and humidity. The effect of moonlight is not statistically significant. These findings provide valuable insights into the environmental factors influencing the migration of T. cristatus, which may guide future conservation efforts.

Redescription of Rhacophorus tuberculatus (Anderson, 1871) and the validity of Rhacophorus verrucopus Huang, 1983 https://herpetozoa.pensoft.net/article/113656/ Herpetozoa 36: 325-333

DOI: 10.3897/herpetozoa.36.e113656

Authors: R. S. Naveen, Shuo Liu, S. R. Chandramouli, S. Babu, P. V. Karunakaran, Honnavalli N. Kumara

Abstract: Rhacophorus tuberculatus and Rhacophorus verrucopus are two morphologically similar species described in 1871 and 1983 respectively. Their taxonomic distinctiveness has been questioned in the past. In the current study, we encountered frogs that we confer to R. tuberculatus based on morphological similarity to a syntype of this species. We redescribe the species based on a re-examination of a syntype, which is designated as a lectotype here, and additional specimens from Garo hills of Meghalaya. We also present molecular data, natural history notes, and report a range extension of this species. Molecular phylogenetic analysis based on the 16S rRNA fragment revealed minimal genetic divergences (0.20–1.74% uncorrected p-distance) between specimens identified as either R. tuberculatus or R. verrucopus from different locations. On the basis of molecular data and morphological characteristics, we conclude that R. verrucopus is a junior synonym of R. tuberculatus.

Geographic distribution of the rare and endangered Telmatobufo venustus (Philippi, 1899) (Anura, Calyptocephalellidae), with the description of a new locality and comments on the type locality https://herpetozoa.pensoft.net/article/107328/ Herpetozoa 36: 335-343

DOI: 10.3897/herpetozoa.36.e107328

Authors: Claudio Correa, José Ignacio Osses, Jesús A. Morales, Juan Carlos Ortiz

Abstract: Telmatobufo venustus was one of the rarest endemic amphibians of Chile until 2020. Prior to that year, this species had been known in four localities, three of them with uncertain location, including the type locality. However, three new precise localities have been reported successively since 2020, all based on a few individuals. In this study, we review the geographic information on the species and, based on literature and other documents, tentatively locate the three localities with uncertain location published before 2020. Furthermore, we describe a new locality near the uncertain southern end of its distribution. Although the number of localities has considerably increased since 2020, the species still has a highly fragmented known distribution, its type locality and southern limit cannot be located with certainty, and it is found in only two state-protected areas. Due to these reasons and because threats to the habitat have been identified in some localities, we suggest keeping the species as Endangered.

Range dynamics of Walterinnesia morgani (Serpentes, Elapidae) during climatic oscillations in Iran https://herpetozoa.pensoft.net/article/107947/ Herpetozoa 36: 317-324

DOI: 10.3897/herpetozoa.36.e107947

Authors: Ali Gholamifard, Mehmet Kürşat Şahin

Abstract: Reptiles have a crucial part in maintaining global biodiversity and the functioning of dynamic ecosystems, owing to their ecological roles and functions. Nevertheless, these organisms are susceptible to human-induced disruptions and the deterioration of their habitats, leading to their categorization as the third most endangered group of vertebrates on a global scale. Understanding the spatial distribution of reptiles is crucial due to their often specific habitat needs and limited vagility. Morgan’s black cobra (Walterinnesia morgani) is a secretive venomous snake species that has thus far received little attention in Iranian scientific literature. The aim of the present study was to determine the existing distribution pattern of the cobra and to speculate on how climatic changes might affect it. Maximum entropy modeling was used to examine a dataset consisting of 16 occurrence records gleaned from field observations and the literature. The niche of the species was predicted using current and future climate change forecasts and bioclimatic and topographical characteristics. The models predicted a future reduction in the wide distribution region of W. morgani in southern and western Iran. It was discovered that climatic factors like temperature range, precipitation dynamics, and river proximity all played a key role in shaping the pattern of distribution. The predicted suitable areas for W. morgani were dependent on water sources; however, future scenarios showed a decline in suitable habitats. This study underscores the importance of conservation efforts in light of the potential implications of climate change on this species. To further understand the range shifts and adaptive strategies of the species, further study of its ecology and dispersal dynamics is required.

Taxonomic status of Lycodon subcinctus sensu lato in China (Serpentes, Colubridae) https://herpetozoa.pensoft.net/article/114206/ Herpetozoa 36: 307-316

DOI: 10.3897/herpetozoa.36.e114206

Authors: Shuo Liu, Mian Hou, Bo Cai, Shimin Li, Zhongxu Zhang, Rui Yu, Dingqi Rao, Liang Zhang

Abstract: The Malayan Banded Wolf Snake Lycodon subcinctus Boie, 1827 once included three subspecies, namely L. s. subcinctus Boie, 1827, L. s. sealei Leviton, 1955, and L. s. maculatus (Cope, 1985). Thereafter, L. s. sealei has been elevated to species level, and the taxonomic status of L. s. maculatus has not been resolved. We sequenced the mitochondrial cytochrome b (cytb) gene fragments of eight specimens of L. s. maculatus from China, including three from the adjacent areas of its type locality. Combining the sequences obtained from GenBank, we reconstructed a molecular phylogeny and reevaluated the taxonomic status of L. s. maculatus. Phylogenetic analysis revealed three highly divergent lineages within L. subcinctus sensu lato which correspond to L. subcinctus sensu stricto, L. sealei, and L. s. maculatus, respectively. Coupled with morphological comparison, we elevate L. s. maculatus to full species and redescribe it based on the type and freshly collected material.

Abstract: The taxonomic status of Gloydius shedaoensis qianshanensis Li, 1999 has long been debated due to its narrow distribution range, low population, loss of type specimens, and lack of detailed descriptions. Neotypes were designated based on newly collected specimens in the Qianshan Mountain area, detailed comparisons between G. s. shedaoensis, and G. s. qianshanensis were recorded, while we redescribed G. s. qianshanensis. PCA results based on the external morphology of the two subspecies of G. shedaoensis demonstrate the inter-population distinction of G. s. shedaoensis and G. s. qianshanensis, including head length, and dorsoventral-postorbital stripe width. Additionally, the ecological data of G. s. qianshanensis were recorded as supplements while providing further conservation strategies.

Notes on the pattern of head size in the Philippine Spotted Flying Lizard, Draco spilopterus (Weigmann, 1834), within Luzon Biogeographic Region, Philippines https://herpetozoa.pensoft.net/article/90412/ Herpetozoa 36: 289-296

DOI: 10.3897/herpetozoa.36.e90412

Authors: Michael A. Tabug, Levy V. Necesito, Arvin C. Diesmos

Abstract: Sexual head dimorphism is a condition where head morphology of male and female of the same species differ, which provides an additional way to recognise sex for species identification. Fifty four adult Philippine Spotted Flying Lizards, Draco spilopterus, were examined from four populations in the Luzon Island, Philippines to assess whether head morphometry can drive sexual dimorphism. We identified the sex and measured five morphometric measurements of the head (jaw length, jaw width, head height, head length, head width) and snout-vent length. A univariate analysis of the five morphometric measurements showed clear sexual dimorphism. Considering all individuals, female heads are significantly larger than those of males (all p-values < 0.05). We also revealed major differences in head size amongst the four populations due to their geographical location and habitat differences.

Exploring the dietary niche of Atlantolacerta andreanskyi (Lacertidae) using DNA metabarcoding https://herpetozoa.pensoft.net/article/103198/ Herpetozoa 36: 281-287

DOI: 10.3897/herpetozoa.36.e103198

Authors: Abderrahim S’Khifa, Ana Pereira, Mohamed Amine Samlali, Tahar Slimani, D. James Harris, Raquel Xavier

Abstract: Determining the dietary niche is an essential part of any conservation strategy, and for modeling the community responses to climate change. DNA metabarcoding methods are revolutionizing such approaches, allowing higher taxonomic resolution than typically possible using microscopy. However, few studies have compared directly the approaches to evaluate the differences in methodology. Here we assess the dietary niches of two genetically diverse populations of Atlantolacerta andreanskyi, a lizard endemic to the Atlas Mountains, Morocco, using DNA metabarcoding of faecal samples, and for one of these we compared the results to two previously published assessments of diets obtained using microscopy of pellets and stomach contents respectively. While results at the Order level were similar, the higher taxonomic resolution obtained in this study provided new insights into the dietary niche of this species. Comparisons between the two populations further highlighted how ecologically distinct these are.

Advertisement calls of Leptobrachella suiyangensis and Leptobrachella bashaensis (Anura, Megophryidae) https://herpetozoa.pensoft.net/article/108125/ Herpetozoa 36: 273-280

DOI: 10.3897/herpetozoa.36.e108125

Authors: Tuo Shen, Shize Li, Jing Liu, Guangrong Li, Xi Xiao, Haijun Su

Abstract: In this study, the advertisement calls of Leptobrachella suiyangensis and Leptobrachella bashaensis are described. The advertisement call of L. suiyangensis includes simple and complex calls, with four different call types and a dominant frequency ranging 4.13–4.82 kHz. The advertisement call of L. bashaensis consists of a single note, with a dominant frequency 6.03–6.46 kHz. We compare the advertisement calls with other species in the genus Leptobrachella, and discuss the definitions of primary advertisement calls and secondary advertisement calls. Our results provide basic data for further acoustic, taxonomic and ecological studies in the genus Leptobrachella.

Sexual dimorphism in postcloacal scales in the northern caiman lizard (Dracaena guianensis) https://herpetozoa.pensoft.net/article/109056/ Herpetozoa 36: 263-272

DOI: 10.3897/herpetozoa.36.e109056

Authors: Riccardo Antonini, Rupert Kainradl, Michaela Gumpenberger, Anton Weissenbacher, Doris Preininger

Abstract: Morphological differences between males and females are common among reptiles. A particularly interesting sexually dimorphic feature whose function is largely unknown is the number and pattern of specific scales. Several lizard species possess an arrangement of centered scales near the cloacal region that differ between the sexes and can be used for sex determination. The presence of postcloacal buttons, sexually dimorphic postcloacal scales on both sides of the body, is an exclusive trait in the subfamily Tupinambinae and is only poorly documented. Here, we investigate postcloacal scales in northern caiman lizards (Dracaena guianensis) housed at the Vienna Zoo. For a period of two years, we documented scale patterns and performed morphometric measurements of individuals of different age classes. Caiman lizards were CT scanned to confirm the sexes. Males exhibit three raised postcloacal scales in a row behind the left and right leg, while females possess one or two large scales surrounded by several smaller scales. The study provides the first evidence that these scales can function as a reliable trait to distinguish the sexes regardless of age or reproductive status. The sexually dimorphic bilateral scale pattern is present immediately after hatching and does not change during development. Scales only increase in thickness and length during growth. We further demonstrate that sexual size dimorphism (SSD) exists in juveniles during ontogenetic development. Juvenile females had a larger SVL, body length, tail length and higher weight compared to juvenile males. This SSD could not be confirmed in adults, and sex determination based on SSD seems unreliable.

Snake shed skin consumed by Kinosternon vogti: a case of interspecific keratophagy https://herpetozoa.pensoft.net/article/109138/ Herpetozoa 36: 259-262

DOI: 10.3897/herpetozoa.36.e109138

Authors: Fabio G. Cupul-Magaña, Nadin E. López-González, Ilse K. Barraza-Soltero, Torsten Blanck, Peter Praschag, Shannon Diruzzo, Taggert G. Butterfield, Armando H. Escobedo-Galván

Abstract: Some reptile species can consume their own shed skin or that of conspecifics; despite its prevalence, the benefits of eating shed skin remain poorly understood. Here, we report a field observation in which a Vallarta Mud Turtle (Kinosternon vogti) consumed a snake shed skin of Masticophis lineatus (Bocourt, 1890) in Bahía de Banderas, Nayarit, Mexico. This type of record could allow us to understand the keratophagous behaviour between and within reptile species.

Occurrence and status of the European Pond Turtle, Emys orbicularis hellenica (Valenciennes, 1833), on Aegean and Ionian Islands (Greece, Turkey) https://herpetozoa.pensoft.net/article/106864/ Herpetozoa 36: 249-257

DOI: 10.3897/herpetozoa.36.e106864

Authors: Mario F. Broggi

Abstract: A study on the occurrence of Emys orbicularis in the Aegean, published in 2012, is here extended to the Ionian Islands. For the first time, a status analysis has also been carried out for the individual islands. Emys orbicularis is found on 11 Greek islands and one Turkish. Its presence on the big islands of Rhodes and Chios has not been ascertained so far, while for four previously mentioned islands there is no confirmation. On Corfu and Lesbos there are still viable larger Emys populations. Most other island occurrences are characterized by small populations. On Kefalonia, Zakynthos, Thassos and Samos, E. orbicularis is in danger of extinction because the wetland biotopes are threatened. In the meantime, many wetlands have been placed under protection. The enforcement of these nature conservation regulations needs to be monitored, and E. orbicularis can be a lead species for such monitoring.

Occurrence and tentative population status of the Balkan Terrapin (Mauremys rivulata, Valenciennes, 1833) on Greek islands https://herpetozoa.pensoft.net/article/100533/ Herpetozoa 36: 233-247

DOI: 10.3897/herpetozoa.36.e100533

Authors: Mario F. Broggi

Abstract: The distribution of Mauremys rivulata on Aegean islands was summarized by Broggi in 2012. Here, the study area encompasses all Greek islands, including the Ionian Islands, and the two Turkish islands of Gökceada and Bozcaada. For the first time, I attempt to estimate the status and size of the populations on the islands. This is a subjective assessment based on my personal visits to most islands and not on IUCN criteria. Mauremys rivulata was found on 29 Greek islands, plus two Turkish islands in the Aegean Sea. Five previously mentioned sites are doubtful, and on the three islands of Sifnos, Syros and Ithaca the species appears to be extinct. On 12 islands I assess its status as “threatened with extinction”. On seven, mostly larger, islands its populations are probably less vulnerable. Efforts must be made for the long-term protection of M. rivulata on the Greek islands.

Expanded description of Hemiphyllodactylus hongkongensis (Squamata, Gekkonidae) https://herpetozoa.pensoft.net/article/106566/ Herpetozoa 36: 225-232

DOI: 10.3897/herpetozoa.36.e106566

Authors: Xiang-Yi Li, Shi-Shi Lin, Zhao-Chi Zeng, Yan-Jun Sun, Jian Wang

Abstract: The expanded description of Hemiphyllodactylus hongkongensis Sung, Lee, NG, Zhang & Yang, 2018 is provided based on four newly collected specimens from eastern Guangdong Province, China, which is beyond its previously known range. The new collection also fills the distribution gap of the genus Hemiphyllodactylus in the region. Due to the absence of sufficient data, we recommend Hemiphyllodactylus hongkongensis be listed as Data Deficient (DD) in the IUCN conservation status categorization.

A new cryptic species of Tylototriton (Amphibia, Caudata, Salamandridae) from mysterious mountain lakes in Manipur, north-eastern India https://herpetozoa.pensoft.net/article/106614/ Herpetozoa 36: 203-224

DOI: 10.3897/herpetozoa.36.e106614

Authors: Ht. Decemson, Hmar Tlawmte Lalremsanga, Premjit Singh Elangbam, Mathipi Vabeiryureilai, Parag Shinde, Jayaditya Purkayastha, Dmitriy V. Arkhipov, Andrey M. Bragin, Nikolay A. Poyarkov

Abstract: An integrative taxonomic analysis combining molecular and morphological lines of evidence revealed a new cryptic species in the Tylototriton verrucosus species group from Manipur, north-eastern India. The new species was previously confused with T. himalayanus and T. verrucosus. Tylototriton zaimeng sp. nov. can be distinguished from its congeners by medium body size, head massive and wide with rounded snout and very wide and protruding supratemporal bony ridges and a well-developed sagittal ridge, short limbs not overlapping when adpressed along body, wide and not segmented vertebral ridge distinct, 13–14 pairs of rib nodules, brown colouration with dull orange to yellowish-brown markings on head, vertebral ridge, rib nodules, palms, soles, vent and ventral tail ridge and by vomerine teeth organised in two distinctly curved bell-shaped series. Phylogenetic analysis of the ND2 and 16S rRNA mtDNA genes confirmed the placement of the new species to the Clade I of the subgenus Tylototriton and suggested it is a sister species of T. panwaensis and T. houi (p-distance 3.0% in ND2 gene). The range of the new species is restricted to the Khongtheng Mountain Range and is isolated from the range of T. panwaensis and T. houi in northern Myanmar and southern China, respectively. We suggest the new species to be considered as Vulnerable (VU) in the IUCN Red List.

Daily activities of water monitors (Varanus salvator macromaculatus Deraniyagala, 1944) in urban wetland, Bangkok, Thailand https://herpetozoa.pensoft.net/article/93492/ Herpetozoa 36: 189-201

DOI: 10.3897/herpetozoa.36.e93492

Authors: Poramad Trivalairat, Sompod Srikosamatara

Abstract: From July to October 2015, a study was conducted on the water monitors (Varanus salvator macromaculatus) at Dusit Zoo in Bangkok, Thailand. A total of 90 monitors were captured, measured for SVL, sexed, and marked on the right axilla. The captured monitors included 70 females and 20 males, resulting in a sex ratio of 3.5:1. Body size did not differ significantly between genders. The monitors exhibited bimodal diurnal activity, with a focus on fish hunting in the morning (06:00–08:00 h) and scavenging for fish leftovers in the afternoon (15:00–17:00 h). After the monitor lizards hunted for prey in the morning, they spent 5–7 hours basking and floating in the lake during the afternoon. Sexual behaviors were also occasionally observed. The monitors displayed frequent predatory behavior towards natural prey, especially fish, in the morning, as opposed to opportunistically scavenging on tourist food and fish leftovers observed throughout the day.

Resurrection and distribution extension of Odorrana heatwolei (Stuart & Bain, 2005) (Anura, Ranidae) https://herpetozoa.pensoft.net/article/106373/ Herpetozoa 36: 177-188

DOI: 10.3897/herpetozoa.36.e106373

Authors: Shuo Liu, Mian Hou, Qiaoyan Wang, Dingqi Rao, Song Li

Abstract: We collected nine specimens of Odorrana Fei, Ye & Huang, 1990 from Xishuangbanna Prefecture, Yunnan Province, China, which is close to the type locality of O. heatwolei (Stuart & Bain, 2005) in Phongsaly Province, northern Laos (approximately 60 km). These specimens agree with the diagnosis of O. heatwolei that body size is large in females and relatively small in males, tympanum large in males and relatively small in females, first finger longer than the second, and glandular dorsolateral fold and external vocal sacs present in males, moreover, these specimens have obvious dense tiny black dots scattered on the dorsum, which is consistent with the characters of O. heatwolei and different from O. tiannanensis (Yang & Li, 1980). Phylogenetically, the sequences of these specimens clustered with the sequence of the holotype of O. heatwolei and formed a distinct clade together, which is sister to O. tiannanensis. We resurrect O. heatwolei and extend the distribution of this species to China.

The current distribution and status of the Hermann’s tortoise, Testudo hermanni boettgeri (Reptilia, Testudines, Testudinidae) in Croatia https://herpetozoa.pensoft.net/article/103510/ Herpetozoa 36: 159-175

DOI: 10.3897/herpetozoa.36.e103510

Authors: Katarina Koller Šarić, Boris Lauš, Ivona Burić, Ana Štih Koren, Toni Koren

Abstract: Hermann’s tortoise (Testudo hermanni) is listed as “Near threatened” in the IUCN Red list of endangered species. The importance of protecting the Hermann’s tortoise populations and its habitats have led to the inclusion of the species within CITES Convention (Annex II), Annex A of EU Wildlife Trade Regulation, Annex II of the Bern Convention and Annexes II and IV of the EU Habitats Directive. To assess the distribution and status of the eastern Hermann’s tortoise (Testudo hermanni boettgeri) in Croatia, historical and recent records were gathered and analyzed. The species was recorded in all three biogeographical regions in the country, but it’s native to the Mediterranean and a small part of the Alpine region. With the increase of recent surveys and the use of citizen science platforms, the known range of the species in Croatia was increased by 35.8% and is now encompassing 123 10 × 10 km EEA reference grid cells. Most records (66%) originate from lower elevations (up to 199 m), and the highest was recorded at 570 m. Sparse forests are the most preferred habitats, followed by semi-open habitats, such as grasslands and shrubs. The most serious threat to the species is natural succession due to the increased abandonment of traditional farming and grazing. Other threats include touristic infrastructure and urban development, transportation, illegal collecting, and invasive species. The Area of Occupancy calculated using 2 × 2 km grids resulted in an AOO of 1,372.00 km2, while Extent of Occurrence (EOO) is calculated to be 18,145.07 km2. The current network of National protected areas includes 14% of the species’ AOO while the designated Natura 2000 areas include 29.30% of its AOO. We propose to designate an additional 10 Natura 2000 areas to help with the long-term protection of the species.

Selection of substrate type, substrate color, and vegetation by tadpoles of Dryophytes plicatus https://herpetozoa.pensoft.net/article/105332/ Herpetozoa 36: 153-157

DOI: 10.3897/herpetozoa.36.e105332

Authors: Renato Sánchez-Sánchez, Olga Méndez-Méndez, Jazmín Hernández-Luría, Geoffrey R. Smith, Julio A. Lemos-Espinal

Abstract: The characteristics of microhabitats in streams can drive the distribution of tadpoles. We experimentally examined microhabitat selection of tadpoles of Dryophytes plicatus. We used a series of choice experiments to test if tadpoles had preferences for particular substrate types, substrate colors, and vegetation. Tadpoles of D. plicatus had a strong preference for mud substrates over sand, gravel, and rock substrates and preferred darker substrates over lighter substrates. Dryophytes plicatus tadpoles used the non-vegetated side of an aquarium more than the vegetated side. Our experimental results matched previous field observations in the case of the preference for mud substrates but differed from the field observations for substrate color and vegetation, suggesting that basic underlying preferences may be modified by various factors in nature or by learning or conditioning.

The validity of Pelophylax chosenicus (Okada, 1931) and P. hubeiensis (Fei & Ye, 1982) (Amphibia, Ranidae) https://herpetozoa.pensoft.net/article/100072/ Herpetozoa 36: 143-152

DOI: 10.3897/herpetozoa.36.e100072

Authors: Sheng-Bo Zhou, Qiu-Yi Zhang, Zi-Qiang Hu, Zu-Yao Xia, Qing Miao, Ping Guan, Jing-Song Shi

Abstract: Pelophylax plancyi (Lataste, 1880), Pelophylax chosenicus (Okada, 1931) and Pelophylax hubeiensis (Fei & Ye, 1982) were described chronologically from East Asia. The three species have similar morphological and molecular characteristics, but the taxonomic relationships amongst them have long been ambiguous. To deal with this taxonomic issue, we examined newly-obtained topotypic specimens of P. plancyi, P. chosenicus and P. hubeiensis for morphological comparison. Furthermore, we investigated the phylogeny of pond frogs in Eurasia by Bayesian Inference and Maximum Likelihood analyses of a fragment consisting of mitochondrial DNA gene 16s and provided a molecular phylogeny of the genus Pelophylax. There were no morphological and molecular differences between P. plancyi and P. chosenicus, but both morphological and molecular differences between P. hubeiensis and P. plancyi. Hence, we conclude that P. chosenicus is a junior synonym of P. plancyi and P. hubeiensis is a separate species from P. plancyi.

The secret life of a rock-dweller: arboreal acrobatics observed in the European leaf-toed gecko Euleptes europaea https://herpetozoa.pensoft.net/article/103465/ Herpetozoa 36: 135-141

DOI: 10.3897/herpetozoa.36.e103465

Authors: Daniele Salvi, Emanuele Berrilli, Giacomo Bruni, Matteo Garzia, Veronica Gomes, Giacomo Radi, Michel-Jean Delaugerre

Abstract: The European leaf toed Gecko, Euleptes europaea, is a strictly nocturnal species endemic to the western Mediterranean and has long been considered a rock-specialist as it is associated with this habitat during its entire daily and life cycle. In this study, we report observations of arboreal behaviour in E. europaea, collected during field research over a 40-year period from across the entire species range. We provide a review of the available information on this topic that contributes to a refined view of the habitat uses and arboreal abilities of this species. Arboreal behaviour in E. europaea was observed throughout the year, across different macrohabitats, on a wide variety of tree, shrub, and bush species, on various parts of the plant (trunk, branches, fronds, twigs, leaves), and at different height from the ground. Remarkably, E. europaea shows an extraordinarily agile arboreal locomotion associated with striking morphological adaptations to an arboreal lifestyle, namely a prehensile tail bearing a terminal adhesive pad that supplements grasping force, an equilibrium asset, and scansor adhesion both in static condition and during escape. We conclude that E. europaea is a climbing gecko (opposed to ground dwelling), occupying both rocky and arboreal microhabitats. While the evolutionary origin and ecological drivers of the arboreal behaviour of E. europaea remains to be fully investigated, this realization has important implications for designing fieldwork research and management strategies for conservation.

New localities and lineages of the Atlas dwarf lizard Atlantolacerta andreanskyi identified using mitochondrial DNA markers https://herpetozoa.pensoft.net/article/103068/ Herpetozoa 36: 129-134

DOI: 10.3897/herpetozoa.36.e103068

Authors: D. James Harris, A. Carolina Varela-Pereira, J. Filipe Faria, Abderrahim S’Khifa, Diana Vasconcelos, Jonathon C. Marshall, Tahar Slimani

Abstract: Atlantolacerta andreanskyi (Werner, 1929) is an endemic lizard from the High Atlas Mountains region of Morocco. A previous molecular assessment of this species using mitochondrial and nuclear DNA markers uncovered extensive genetic diversity with seven lineages indicative of a species complex. A morphological assessment of six of these lineages did not establish simple diagnostic features, and proposed these should be considered as a cryptic species, while highlighting the need for greater sampling across the range. In this study, we sampled 8 individuals from 5 previously unsampled localities and carried out genetic analyses to compare these populations to the known variation. Phylogenetic reconstruction based on mitochondrial DNA markers (12S rRNA and ND4) corroborates the previously described lineages and identified a new one. Interestingly, the two samples that account for this newly identified lineage have been collected from distinct localities – M’goun and Toumliline – that form a sister taxon to the population of Jbel Azourki.

DOI: 10.3897/herpetozoa.36.e101646

Authors: Tianyu Qian, Guoxing Deng, Yonghui Li, Daode Yang

Abstract: We describe the advertisement call of the Nanling horned frog, Boulenophrys nanlingensis for the first time, based on recordings obtained from four individuals. One of these individuals, which was identified using its dorsum pattern, was recorded twice after nine months. Distinct shifts in the temporal parameters and call rate were observed from calls of the re-captured individual, which was suspected to be related to temperature and social context. However, due to the limited sample size, further research is needed to confirm these findings. We highlight the potential of mark-recapture method using dorsum pattern for studying and monitoring the Nanling horned frog and other megophyinid frogs.

New survey data on abundance and movements for two poorly known Asian Spiny Frogs https://herpetozoa.pensoft.net/article/100649/ Herpetozoa 36: 113-121

DOI: 10.3897/herpetozoa.36.e100649

Authors: Arooj Batool, Muhammad Rais, Muhammad Saeed, Ayesha Akram, Jamal Ahmed, Waseem Ahmed, Arfaa Batool, Kirsty Jane Kyle

Abstract: We present new natural history data on abundance and movements (daily and seasonal) during the pre-breeding (March-June) and breeding-post-breeding season (July-September) of two poorly studied frog species of the Himalayas, Nanorana vicina and Allopaa hazarensis. We estimated 185 Murree Hills Frogs and 90 Hazara Frogs within the study area (0.79 ha). The daily and seasonal movement data showed that the two species moved either between neighboring ponds or remained in an array of smaller ponds (within an area of 120 m2) along the stream bank. About 75% of movements were < 29.5 m in N. vicina and < 50.87 m in A. hazarensis during pre-breeding season while < 41.5 m in N. vicina and < 81 m in A. hazarensis during breeding-post-breeding season. We suggest inclusion of amphibian habitat requirements and ensuring stream connectivity in urban planning and development projects in the area to prevent the local extinction of the endemic species. In the future, more robust and long-term studies, encompassing more streams situated within a wider area, would help clarify dispersal, colonization, metapopulation structure, and dynamics of these endemic frogs of the forested montane streams in the Himalayan Foothills.

Authors: Christoph I. Grünwald, Carlos Montaño-Ruvalcaba, Jason M. Jones, Iván Ahumada-Carrillo, André J. Grünwald, Jiacheng Zheng, Jason L. Strickland, Jacobo Reyes-Velasco

Abstract: We describe a new species of Eleutherodactylus (subgenus Syrrhophus) from Guerrero, Mexico, based on morphological and molecular data, as well as advertisement call analysis. Eleutherodactylus franzi sp. nov. has unique features including widely expanded fingertips, indistinct, but visible lumbo-inguinal glands, an immaculate white venter and dark reticulations on a cream dorsal background colouration. The new species belongs to the Eleutherodactylus nitidus species group. Eleutherodactylus franzi sp. nov. is micro-endemic, restricted to a small range in karstic hillsides on the southern extreme of the Mexican Transverse Ranges. We discuss conservation needs of this species, which we provisionally classify as Critically Endangered.

The herpetofaunal diversity of Takhar Province, Afghanistan https://herpetozoa.pensoft.net/article/98319/ Herpetozoa 36: 73-90

DOI: 10.3897/herpetozoa.36.e98319

Authors: Daniel Jablonski, Faizurrahman Khalili, Rafaqat Masroor

Abstract: Takhar Province of Afghanistan was previously known to harbour only two species of amphibians and eight species of reptiles with no record of snake species. From 2020 to 2021, we collected herpetological data from the Province and identified 14 species and specimens representing species complexes (Bufotes viridis complex and Trapelus agilis complex), with first records of Testudo horsfieldii (Testudinidae), Paralaudakia badakhshana (Agamidae), Pseudopus apodus (Anguidae), Tenuidactylus caspius (Gekkonidae), Eumeces schneideri (Scincidae) and Varanus griseus (Varanidae). In addition, we report the first province records of snakes, including Eryx tataricus (Erycidae), Hemorrhois ravergieri (Colubridae), Natrix tessellata (Natricidae) and the venomous species Naja oxiana (Elapidae). These records connect and supplement previously obtained data of these species from surrounding provinces and neighbouring countries. Our data reveal that Takhar Province is home to at least 20 species of amphibians and reptiles with a strong affiliation to the Turanian chorotype. All these data are a significant source of information for the diversity of herpetofauna in Afghanistan and subsequent biodiversity research in the Central Asiatic region.

Microhabitat sharing for basking between squamate species in Poland https://herpetozoa.pensoft.net/article/94064/ Herpetozoa 36: 65-71

DOI: 10.3897/herpetozoa.36.e94064

Authors: Przemysław Zdunek, Maksymilian Jarmoliński

Abstract: Aggregations (e.g. group basking) by snakes are usually limited to specific life cycle phases (e.g. mating) or are a consequence of drastic environmental changes (e.g. habitat destruction), high prey densities or highly limited resources within an environment (e.g. basking sites, wintering dens). Here, we report intra- and interspecific observations of four reptile species (primarily Natrix natrix and Vipera berus) sharing basking sites at the confluence of the rivers Dunajec and Poprad near the town of Stary Sącz in southern Poland. From a total of 84 records in the field between 2020–2022, there were 11 interactions from 24 July 2020 to 1 May 2022. Previous studies have indicated direct competition or interference in many species, which we did not observe. There is a noticeable lack of such observations of microhabitat sharing for basking between squamate species in scientific literature. Hence, the accumulation of such observations has the potential to reveal new insights into the behaviour and ecology of N. natrix and V. berus.

The advertisement calls of Pristimantis galdi Jiménez de la Espada, 1870 and Pristimantis katoptroides (Flores, 1988) (Anura, Strabomantidae) https://herpetozoa.pensoft.net/article/97705/ Herpetozoa 36: 59-64

DOI: 10.3897/herpetozoa.36.e97705

Authors: Diego Batallas, Jorge Brito

Abstract: In this study we describe for the first time the calls of Pristimantis galdi and Pristimantis katoptroides. Recordings were obtained in Sangay National Park, Ecuador. We highlight the importance of recording P. galdi since its call has been recorded after 153 years of having been described as a species. The call of P. galdi consists of 7 to 9 short notes, the sounds of which are similar to a hammer hitting a nail, with a mean dominant frequency of 2.39 kHz. In turn, the call of P. katoptroides consists of a single note, the sound of which is similar to a metallic “tic”, with a mean dominant frequency of 1.74 kHz. We compared the advertisement calls of P. galdi, P. katoptroides and P. roni as these species share similar morphological characteristics and are grouped in the spiny green frog’s ecotype. Despite these morphological similarities, their advertisement calls are different. Obtaining calls of Pristimantis species in Ecuador might prove difficult with short-term studies due to the great sampling efforts that may be needed to get these recordings. Therefore, implementing active and passive monitoring could help improve our knowledge of acoustic signals in Ecuador’s rainfrogs.

A contribution to taxonomy and biology of Spalerosophis diadema diadema (Schlegel, 1837) along with a new record of Spalerosophis atriceps (Fischer, 1885) from the Poonch District of Jammu and Kashmir, India (Reptilia, Squamata, Colubridae) https://herpetozoa.pensoft.net/article/94456/ Herpetozoa 36: 41-52

DOI: 10.3897/herpetozoa.36.e94456

Authors: Sarshad Hussain, Khursheed Ahmad, Asgar Ali Shah

Abstract: The present study is aimed to validate the occurrence of two species of Diadem or Royal snakes of Genus Spalerosophis Jan, 1865 from the Poonch District of Jammu and Kashmir, India along with the presentation of eight different colour morphs and diagnostic characteristics. The eight different colour morphs include four colour morphs of adults of S. d. diadema (Schlegel, 1837), two colour morphs of adults of S. atriceps (Fischer, 1885), one colour morph of subadults of unknown parentage and one colour morph of the adult of S. diadema (Schlegel, 1837) represented by a single individual whose identification at subspecies level (ssp. cliffordii/diadema) is the subject for further investigations for want of more specimens. This solitary specimen shares many similarities with S. d. diadema, but it has less number of sub-caudal scales which point towards the likelihood of S. d. cliffordii (Schlegel, 1837). The distribution, activity, habitat and behaviour have also been reported along with the morphological, morphometric and meristic characters. Between two identified species S. atriceps is a new report from the Poonch District. Reported specimens are mapped across the study area and are depicted here in the distribution map.

Body size and body condition in the nose-horned viper (Vipera ammodytes): effects of sex and populations https://herpetozoa.pensoft.net/article/98931/ Herpetozoa 36: 53-58

DOI: 10.3897/herpetozoa.36.e98931

Authors: Tijana Čubrić, Xavier Bonnet, Jelka Crnobrnja‐Isailović

Abstract: Snakes are ecologically and morphologically plastic organisms that exhibit extensive variations in body size and body condition in response to environmental factors. Documenting inter-population variations is important to describe species comprehensively across their distribution range and to monitor trends over time (e.g. decreasing body condition due to alteration of habitat). Thus, we analyzed the influence of population and sex on body size and body condition in three populations of nose-horned vipers (Vipera ammodytes) in Serbia. In one population, males were larger than females (F1, 39=4.802, p=0.034), but not in the two other populations (F1, 36=0.075, p=0.786; F1, 21=0.018, p=0.893). Females exhibited higher body condition (residual values from the regression of log-body mass against log-body size) than males (F1, 90=10.444, p=0.002); this sex difference was not found in one population when analyzed separately (F1, 35=1.834, p=0.184). Moreover, we found strong inter-population differences in mean body size and mean body condition (F2, 96=8.822, p<0.001 and F2, 90=10.319, p=0.001, respectively). While inter-population difference in body size was driven by males, inter-population difference in body condition was driven by females. These results suggest that, in this species, body size might be an important determinant of mating success in males, while body condition may play a major role in female fecundity.

First record of Hoplobatrachus litoralis Hasan, Kuramoto, Islam, Alam, Khan & Sumida, 2012 (Anura, Dicroglossidae) from China https://herpetozoa.pensoft.net/article/98669/ Herpetozoa 36: 31-39

DOI: 10.3897/herpetozoa.36.e98669

Authors: Shuo Liu, Mian Hou, Dingqi Rao, Song Li

Abstract: We report the first record of Hoplobatrachus litoralis Hasan, Kuramoto, Islam, Alam, Khan & Sumida, 2012 from China based on seven specimens from Baoshan City, western Yunnan. Morphologically, the specimens from China mostly agree with the original description of H. litoralis and phylogenetically show a small genetic distance (1.7%) in the 16S rRNA gene with the specimens (including one paratype) of H. litoralis from its type locality in Bangladesh. Our work increased the species number of the genus Hoplobatrachus Peters, 1863 in China to two. This record is the easternmost distribution of this species at present. Furthermore, we found that the species H. salween Thongproh, Chunskul, Sringurngam, Waiprom, Makchai, Cota, Duengkae, Duangjai, Hasan, Chuaynkern & Chuaynkern, 2022 recently described from north-western Thailand is morphologically and genetically very similar to H. litoralis and, therefore, we discuss the validity of H. salween as a separate species.

Trophic ecology of the Atlantic Forest endemic tree frog Boana bischoffi (Boulenger, 1887) (Anura, Hylidae) https://herpetozoa.pensoft.net/article/95863/ Herpetozoa 36: 23-29

DOI: 10.3897/herpetozoa.36.e95863

Authors: Gabriela de Araujo Pereira, Célio F. B. Haddad, Marcelo José Sturaro

Abstract: Studies of natural history are important to accumulate knowledge about aspects of diet, reproduction, and habitat use, which can assist the conservation biology for endangered groups, such as amphibians. Here we evaluated the trophic ecology and sexual size dimorphism of Boana bischoffi, a widely distributed and endemic tree frog species of the Brazilian Atlantic Forest. We analysed 80 individuals, covering the distribution of the species and combined our data-set with data from the literature. Gastrointestinal items were separated, accounted, and identified to the highest possible taxonomic resolution. Subsequently, the size and mass of prey items were measured. Afterwards, we calculated rates of relative importance for each prey category. The items of greatest relative importance were beetles (Coleoptera), termites (Isoptera), crickets (Orthoptera) but also harvestmen (Opiliones). We did not find a relation between female snout-vent length, mouth width and length with prey length. In males, the mouth length and width are related to prey length. We found a sexual dimorphism in size typical for hylid frogs, with females being larger than males. Our data expand the knowledge about the alimentary biology of B. bischoffi, but further research focusing on other aspects of the natural history such as possible intersexual dietary divergence and food niche overlapping, environmental prey availability and selection is still needed.

A new species of saxicolous Lepidophyma (Squamata, Xantusiidae) from Tamaulipas, Mexico https://herpetozoa.pensoft.net/article/96184/ Herpetozoa 36: 9-21

DOI: 10.3897/herpetozoa.36.e96184

Abstract: We describe a new saxicolous species of Lepidophyma from the Sierra Madre Oriental, in the state of Tamaulipas, Mexico and provide morphological and molecular data to support the novelty of this species. The new species is most closely related to members of the L. sylvaticum group; however; it is a flattened form specialised for a saxicolous lifestyle and it can be distinguished from all other members by a combination of meristic characters. Genetic analysis suggests that several populations of L. sylvaticum might represent additional novel taxa, while the validity of L. micropholis is questioned. We discuss conservation priorities of the new species.

Observation records of the Bangon Monitor Lizard, Varanus bangonorum (Squamata, Varanidae), with emphasis on behaviour and local threats, from the Municipality of Abra de Ilog, Occidental Mindoro, Philippines https://herpetozoa.pensoft.net/article/96841/ Herpetozoa 36: 1-8

DOI: 10.3897/herpetozoa.36.e96841

Authors: Przemysław Zdunek, Michaela S. Webb

Abstract: Varanus bangonorum, the Bangon Monitor Lizard, is one of eleven Varanidae species endemic to the Philippines; its occurrence is restricted to dwindling habitats on the islands of Mindoro and Semirara. This lizard is still poorly known and is presently classified as “Least Concern” under the IUCN Red List in 2022. Observations recorded during eleven years (2011 to 2022) originate from the north-central Municipality of Abra de Ilog in Occidental Mindoro where this species was never before documented. We emphasise the primary factors that pose threats to the monitor lizard population, including insights gained from the knowledge of local community members. We present information about the lizards’ diet, for example, they can consume invasive toxic cane toads without harm. The result of our collective long-term observation records may serve as a baseline for further studies and contribute to evaluating the conservation status of this species.

The incidence of the anomaly P syndrome in water frogs (Anura, Ranidae, Pelophylax) from the Middle Volga River (Russia) https://herpetozoa.pensoft.net/article/95928/ Herpetozoa 35: 283-288

DOI: 10.3897/herpetozoa.35.e95928

Authors: Anton O. Svinin, Oleg A. Ermakov, Spartak N. Litvinchuk

Abstract: The anomaly P is a widespread morphological anomaly, which occurs in some groups of amphibians, caused by the trematode parasite Strigea robusta (Digenea: Strigeidae). This anomaly has been previously recorded in water frogs of the genus Pelophylax and toads of the genera Bufo and Bufotes. The anomaly P includes symmetrical polydactyly cases as a mild attenuated form of the complex syndrome, which in severe cases includes strong deformations of hindlimbs and forelimbs. Strigea robusta has a complex 3-host life cycle using planorbid mollusks as the first intermediate hosts, amphibian larvae as the second intermediate hosts, and anatid birds as the definitive hosts. Herein, we described new records of the anomaly P syndrome in water frogs of the genus Pelophylax from the northeastern parts of their ranges. Symmetrical polydactyly (as a mild form of the anomaly P syndrome) was found in 30 individuals of three species of water frogs from seven localities: in 25 individuals of P. lessonae from four waterbodies, in four individuals of P. ridibundus from three waterbodies, and one individual of P. esculentus. In Gusevo pond, three individuals of P. lessonae with severe cases of the syndrome were found. This is the first record of the anomaly P in reliably identified hybridogenetic edible frogs (P. esculentus) that have been identified in nature. Additionally, we provided new data about the occurrence of the anomaly P and the prevalence of the trematode S. robusta in mollusks taken from two water bodies where anomalous water frogs were found.

On the validity of Hebius sauteri maximus (Malnate, 1962) (Squamata, Natricidae), with the redescription of H. maximus comb. nov. and H. sauteri (Boulenger, 1909) https://herpetozoa.pensoft.net/article/94920/ Herpetozoa 35: 265-282

DOI: 10.3897/herpetozoa.35.e94920

Authors: Mao-Liang Li, Jin-Long Ren, Jun-Jie Huang, Zhi-Tong Lyu, Shuo Qi, Ke Jiang, Ying-Yong Wang, Jia-Tang Li

Abstract: Hebius sauteri (Boulenger, 1909) has been long recognized as a widely distributed species with three subspecies, namely Hebius sauteri sauteri from Taiwan Island and southeastern China, Hebius sauteri bourreti (Malnate, 1962) from northern Vietnam, and Hebius sauteri maximus (Malnate, 1962) from Sichuan, southwestern China. However, the validity of these subspecies of the H. sauteri complex has not been evaluated. In the current study, we re-evaluate the taxonomic status of H. s. maximus based on morphological and molecular evidence. Molecular phylogenetic results indicate that H. s. maximus is a distantly diverged clade with respect to H. s. sauteri, and that H. s. maximus is morphologically distinguishable from the nominative subspecies. Therefore, our results support the validity of H. s. maximus and we elevate it to full species status, namely Hebius maximus comb. nov. The distribution range of H. sauteri is revised according to our proposed taxonomic change. Furthermore, detailed redescription, natural history, and coloration of both H. sauteri and H. maximus and comments on the validity of H. s. bourreti are also provided.

Melanism in the grass snake Natrix natrix (Linnaeus, 1758) from the Danube Delta Biosphere Reserve, Romania https://herpetozoa.pensoft.net/article/85310/ Herpetozoa 35: 257-263

DOI: 10.3897/herpetozoa.35.e85310

Authors: Geanina Fănaru, Alexandra E. Telea, Iulian Gherghel, Raluca Melenciuc

Abstract: Animal colouration has a significant ecological role in defence, reproduction, and thermoregulation. In the case of melanism, it is a complex topic. Besides potential disadvantages such as higher risk of predation, melanistic ectotherms may have certain physiological advantages such as more efficient thermoregulation in colder climates and thus, reduced basking time. The common grass snake (Natrix natrix) is a widespread species throughout Europe and Asia. It exhibits a wide range of colour polymorphisms, from olive to dark grey, even albinistic and melanistic. Between 2016 and 2021, we conducted fieldwork in the Danube Delta Biosphere Reserve (DDBR) with the aim to document the geographic range of melanistic grass snakes. We categorised the melanistic expressions of N. natrix individuals as melanotic, completely melanistic, and partially melanistic. Melanistic snakes were encountered in all six localities visited, suggesting that the occurrence of melanistic grass snakes in the DDBR is geographically widespread. We observed both juveniles (n=2) and adults (n=11) with melanism, suggesting that individuals are born melanistic. However, the proportion of melanistic individuals in the general population of N. natrix from the DDBR is unknown. Only at Histria locality we studied the proportion of melanism in the grass snake population and 6.3% of the snakes caught were melanistic. Body size comparisons are not statistically significant because of the low sample size. The N. natrix melanistic morph’s geographical distribution in the DDBR is most likely due to an interaction of climate and habitats, which offer a thermal advantage in the face of predation pressure.

Ecomorphological differences among forest and rock dwelling species of Darevskia Arribas, 1999 (Squamata, Lacertide) in the Elburz Mountains, Iran https://herpetozoa.pensoft.net/article/95257/ Herpetozoa 35: 245-256

DOI: 10.3897/herpetozoa.35.e95257

Authors: Seyyed Saeed Hosseinian Yousefkhani, Hossein Nabizadeh, L. Lee Grismer

Abstract: Ecological pressure is the major driver of morphological adaptation. Different habitat preferences even among closely related species, often result in the evolution of different body shapes. In the present study, we employed geometric morphometric and principal component analyses (PCA) to compare body shape and head plate morphology among seven species in the genus Darevskia Arribas, 1999 from the Elburz Mountains, Iran that occur in either rocky or forested habitats. The geometric morphometric analysis and the PCA of meristic characters recovered a wide degree of overlap between the rock and forest dwelling species. The PCA of the morphometric characters showed wide separation among the rock and forest dwelling species as well as among some of the rock dwelling species. These results strongly suggest that body shape is correlated with the habitat type whereas head plate morphology and scale meristics are not. Furthermore, the results suggest that the rock dwelling species may be occupying and navigating their microhabitat in different ways. Ecological observations are needed to test this hypothesis.

Abstract: Urban habitats receive an increasing number of species due to anthropogenic activities, mainly transportations. Here, we report a new addition to the herpetofauna of Athens (Greece): a small population of the Pelasgian wall lizard (Anatololacerta pelasgiana) was found in a suburb of the Athenian metropolitan area. The species normally occurs in southwestern Anatolia and southeastern Aegean islands and this is the first record in the Greek mainland. Allochthonous species that successfully colonize cities raise new challenges to urban ecology.

DOI: 10.3897/herpetozoa.35.e94745

Authors: Yin-Peng Zhang, Xiao-Long Liu, Bryan L. Stuart, Dong-Yi Wu, Yu-Fan Wang, Jing Che, Zhi-Yong Yuan

Abstract: Amolops putaoensis is a recently described torrent frog species from A. monticola group that is known only from its type locality, northern Myanmar. We compared morphology and mitochondrial DNA sequence data from ten recently collected adult male specimens from the upper Dulong River System in Gongshan County, Yunnan Province, China, to the original description of A. putaoensis. Both datasets strongly supported referring the Chinese specimens to A. putaoensis, extending the known range of this species by approximately 133.7 km distance into China. Molecular phylogenetic analyses recovered A. putaoensis to be closely related to A. aniqiaoensis, A. kohimaensis, A. monticola, and A. adicola. We use the newly collected Chinese specimens to expand the morphological description of the species.

Multimale breeding aggregations by “many-friends” snakes: courtship behaviours by Malagasy Pseudoxyrhophiine snakes, Dromicodryas bernieri and D. quadrilineatus, and their sexual size dimorphism https://herpetozoa.pensoft.net/article/91579/ Herpetozoa 35: 225-229

DOI: 10.3897/herpetozoa.35.e91579

Authors: Ryobu Fukuyama, Akihiro Itoigawa, Akira Mori

Abstract: When several male snakes dispute over one female in the breeding season, two major male-male rivalries are known to occur: male-male combat and multimale breeding aggregation. The roles of male body size and the degree of sexual size dimorphism are different between these rivalries. We report field observations of mating behaviour including a multimale breeding aggregation of pseudoxyrhophiins, Dromicodryas bernieri and D. quadrilineatus, in northwestern Madagascar, which have a local name, “Maro longo”, meaning “many friends”. To examine the relationships between sexual size dimorphism and mating strategies of males, we also analysed the body size of the two species of Dromicodryas and two other pseudoxyrhophiins, Leioheterodon madagascariensis and L. modestus, which are known to exhibit the male-male combat. Our data obtained during a long-term field study showed that D. bernieri and D. quadrilineatus have female-biased sexual size dimorphism, whereas L. madagascariensis and L. modestus have male-biased sexual size dimorphism. This result conforms to the general tendency of the relationship between body size and male-male rivalry in snakes.

Authors: Cristopher A. Antúnez-Fonseca, Marcio Martínez, Travis W. King, Diego I. Ordoñez-Mazier, Larry D. Wilson, Manfredo A. Turcios-Casco

Abstract: The family Polychrotidae Fitzinger, 1843 is represented in Honduras by a single species, Polychrus gutturosus Berthold, 1845. This canopy dweller is distributed in the lowland moist forests and riparian forest within pine savannah of the northern and eastern regions of Honduras. Only 13 records and nine localities support the presence of the species in the country; therefore, the distribution and natural history of the species in Honduras is essentially unknown. Herein, we provide a new locality and natural history observations of a specimen captured in the core zone of the Reserva del Hombre y La Biosfera del Río Plátano. This record represents the north-western most occurrence of Polychrus gutturosus in a region known as the Mosquitia and fills an important distributional gap for this poorly known species.

Erythrism in the Eastern Grass Snake, Natrix natrix (Linnaeus, 1758) https://herpetozoa.pensoft.net/article/90928/ Herpetozoa 35: 213-217

DOI: 10.3897/herpetozoa.35.e90928

Authors: Daniel Jablonski, Benny Trapp, Elias Tzoras, Konrad Mebert

Abstract: We describe the unusual case of erythrism in the Eastern Grass Snake, Natrix natrix. This colour morph is very rare and has not been reported in the literature before. Despite having observed thousands of N. natrix in the field, we personally detected this morph in only three individuals originating from Slovakia, Romania, and mainland Greece, while photos of a fourth individual from a Greek island were provided to us. In addition, a recent study with a large data set from citizen scientists was unable to produce a single reddish Eastern Grass Snake. Such colouration is likewise uncommon in the western members of Grass Snakes (N. helvetica, N. astreptophora), with two examples provided herein. Because the potential biological importance of erythristic colouration is unclear, we encourage other field herpetologists and naturalists to publish their observations of reddish Grass Snakes in the printed literature.

Abstract: Podarcis wall lizards mainly feed on coleopterans, orthopterans, arachnids, and other small invertebrates. However, Aegean wall lizards, Podarcis erhardii, are widely distributed across Aegean islands and are increasingly observed eating non-traditional food items ranging from plant material to conspecific eggs and body parts. Here, we report the first documented case of P. erhardii consuming a large centipede, Scolopendra cingulata. The predator-prey relationship between these species has appeared to go both ways and may intensify on islands.

Abstract: The diet of lizards is mainly composed of arthropods. It can be affected by biotic and abiotic factors, which influence the energy supply provided by the composition of the animal´s diet. The richness and abundance of many arthropod species can be influenced by environmental seasonality, especially in the Caatinga ecoregion, due to the rainfall regimes. The present study aims to describe aspects of the seasonal and morphological variation in the lizard Gymnodactylus geckoides diet and their energy content. We collected 157 individuals (63 females, 68 males, and 26 juveniles) at the Catimbau National Park, Northeastern Brazil, of which 72 were analyzed for the dry season and 59 for the rainy season. Our data indicates Isoptera to be the most common prey in G. geckoides’s diet. Energy content, prey number was higher in the dry season, whereas prey volume and glycogen content increased in the rainy season. Proteins and lipids did not show marked differences. The present study represents the first effort to understand variations in G. geckoide’s trophic ecology, indicating that this specie presents a wide variation in their diet, especially when considering seasonal factors, revealing their needs and restrictions according to prey availability and environmental conditions.

Abstract: Chilapata rain-pool frog (Minervarya chilapata) was described in 2009 from the Chilapata Reserve Forest of West Bengal, India. Here, we report the occurrence of M. chilapata for the first time from Morang district, Nepal, based on acoustic and morphological characters such as the presence of a distinct white line in the upper lip, small size (snout-vent length 18 to 26 mm), pointed snout and presence of dorso-lateral black patch. The nearest record of Chilapata rain-pool frog in Nepal from Pathari-Kanepokhari forest, Morang district, Nepal is ca.182 km west of its type locality Chilapata Reserve Forest, Jalpaiguri district, West Bengal, India. We also report the occurrence of M. chilapata from Barandabhar Biological Corridor, Chitwan National Park, Nepal based on a photographic record. The International Union for Conservation of Nature (IUCN) has listed the species as Data Deficient. Therefore, this record from Nepal will add new presence data for future status assessment for the species.

A tale about vipers’ tails: phylogeography of black-tailed rattlesnakes https://herpetozoa.pensoft.net/article/84297/ Herpetozoa 35: 141-153

DOI: 10.3897/herpetozoa.35.e84297

Authors: Víctor Hugo Muñoz-Mora, Marco Suárez-Atilano, Ferruccio Maltagliati, Fabiola Ramírez-Corona, Alejandro Carbajal-Saucedo, Ruth Percino-Daniel, Joachim Langeneck, Maristella D’Addario, Armando Sunny

Abstract: The phylogenetic relationships among black-tailed rattlesnakes remain poorly understood and some authors indicated that the diversity of this group has been underestimated and additional analyses are required to clarify the biogeographic patterns throughout its distribution in Mexico. Therefore, the aim of this study was to elucidate the phylogenetic relationships among black-tailed rattlesnakes across their range, identifying relative divergence times among the main clades and reconstructing the biogeographical history of the group. Three partial mitochondrial genes (ND4, cytb and ATPase6) and one nuclear gene (RAG1) were sequenced to infer the phylogenetic relationships, through the maximum likelihood and Bayesian inference-based methods; demographic history reconstruction was investigated through Bayesian Skyline plot analysis and the ancestral area reconstruction was carried out considering a Bayesian framework. We found strong evidence that the black-tailed rattlesnakes’ group is composed of six clades, which is in agreement with subspecies previously reported. Divergence time estimation indicated that the origin of the C. molossus group could be traced to the middle of the Miocene (~7.71 Mya). Ancestral area reconstruction indicated that early divergence events occurred in Central Mexico, probably related to the geological dynamics of the Trans-Mexican Volcanic Belt. The lineage C. m. oaxacus is the basal member of the C. molossus group. Furthermore, the combination of geological events and changes in Quaternary vegetation may have contributed to the divergence of C. molossus clades. Our results suggest several clades within C. molossus complex could be potentially recognized as separate species.

The distribution of the critically endangered salamander Paradactylodon (Afghanodon) mustersi (Smith, 1940) in Afghanistan https://herpetozoa.pensoft.net/article/86028/ Herpetozoa 35: 133-139

DOI: 10.3897/herpetozoa.35.e86028

Authors: Ahmad Samim Ayobi, Rafaqat Masroor, Abdul Basit, Daniel Jablonski

Abstract: The Afghanistan Mountain Salamander, Paradactylodon (Afghanodon) mustersi (Smith, 1940), is an evolutionary old species, listed as Critically Endangered by IUCN Red List. The species is endemic to the Hindu Kush mountain range with records from only a few localities from four central-eastern Afghan provinces (Kabul, Ghazni, Parwan, and Wardak). Due to the long-term complicated political situation in the country which makes zoological research almost impossible, the current distribution and the presence of P. mustersi at previously known localities has remained unassessed for 40 years. We carried out recent, sporadic surveys between 2017 and 2021 to detect P. mustersi in three tributaries of the Paghman stream on the southern slopes of the Hindu Kush Mountains and the two nearby provinces (Panjsheer and Parwan), where the presence of the species was expected. We confirmed the occurrence of P. mustersi at all survey sites, and present the first record of the species for Panjsheer Province. We also confirmed that the species is currently endangered by human-mediated factors like habitat disturbance (increased visitors attendance, water pollution, construction activities), especially in the Paghman area.

Chromatic and morphological anomalies in gymnophionans from India https://herpetozoa.pensoft.net/article/76397/ Herpetozoa 35: 121-132

DOI: 10.3897/herpetozoa.35.e76397

Abstract: Caecilians (Gymnophiona) are commonly known as limbless amphibians and are the least understood vertebrate order. In this paper, we documented skin color, eye, jaw, snout, tentacular aperture and cloacal anomalies in 12 individuals of four species belonging to the three caecilian genera Ichthyophis, Uraeotyphlus and Gegeneophis collected from hotspots of caecilian diversity in India, the Western Ghats and Northeast India. As we found the majority of these individuals in coffee and tea plantations, we discuss the possibility that anomalies are the result of exposure to agrochemicals that are frequently used in plantations.

Developmental anomalies in the smooth snake, Coronella austriaca Laurenti, 1768 (Squamata, Colubridae) from Poland https://herpetozoa.pensoft.net/article/85951/ Herpetozoa 35: 115-120

DOI: 10.3897/herpetozoa.35.e85951

Authors: Bartłomiej Najbar, Anna Najbar, Grzegorz Sapikowski, Krzysztof Kolenda, Tomasz Skawiński

Abstract: We present four cases of rare developmental anomalies in the smooth snake Coronella austriaca Laurenti, 1768 from western Poland. These include brachycephaly, lordosis, a supernumerary row of ‘ventral’ scales, and the third reported case of dicephalism in snakes from Poland. All the cases are supported by X-ray radiography. One of the possible explanations for these anomalies is a low genetic variation in populations from western Poland.

Diet of the exotic Madeiran wall lizard: first insights into trophic interactions in an Atlantic seabird sanctuary https://herpetozoa.pensoft.net/article/82096/ Herpetozoa 35: 107-113

DOI: 10.3897/herpetozoa.35.e82096

Authors: Verónica Neves, Dorothee Rund, Catarina J. Pinho, Raquel Vasconcelos, Paco Bustamante, Petra Quillfeldt

Abstract: The Madeiran wall lizard Teira dugesii is a relatively new species to the Azores Archipelago, where it was accidentally introduced about 150 to 200 years ago. This lacertid quickly became naturalised and now occurs in all the nine main islands of the Azores. At Praia Islet, off Graciosa Island, the Madeiran wall lizard was recently observed preying on chicks of the threatened Monteiro’s storm-petrel Hydrobates monteiroi. To characterise the lizards’ trophic niche, we conducted a study of the diet of the Madeiran wall lizard at Praia using stable isotope analysis and next-generation sequencing. Our results indicate that the Madeiran wall lizard has a varied diet, consisting of at least 23 invertebrate taxa, 17 plant species, and occasionally, birds (two species detected, including storm-petrels). Marine derived food items were present in few samples, and it is vital to monitor the trophic interactions at Praia Islet to ensure the conservation of this threatened storm-petrel.

Gigantism in tadpoles and color anomalies in European green toad Bufotes viridis from Poland https://herpetozoa.pensoft.net/article/84228/ Herpetozoa 35: 95-98

DOI: 10.3897/herpetozoa.35.e84228

Authors: Michał Szkudlarek, Jan Marek Kaczmarek, Marta Piasecka, Wiktor Grenas, Mikołaj Kaczmarski

Abstract: Some new cases of anomalies in wild Bufotes viridis from Western Poland are presented together with a discussion of their potential causes and a comparison with similar cases from the literature. The anomalies in question are color aberrations (pre- and post-metamorphic) and developmental pathologies (pre–metamorphic). The color anomalies include an ochre patch in a juvenile, leucism and albinism in both tadpoles and juvenile individuals. Developmental pathologies described in this paper include gigantism, edema, curvature of tail, and asymmetric bodies.

A new subspecies of the Asiatic softshell turtle Amyda ornata (Gray, 1861) from its northern distribution range https://herpetozoa.pensoft.net/article/86055/ Herpetozoa 35: 81-93

DOI: 10.3897/herpetozoa.35.e86055

Authors: Peter Praschag, Richard Gemel

Abstract: We describe a new subspecies of Amyda ornata (Gray, 1861) from the southeastern parts of Bangladesh (Chittagong hill tracts), adjacent regions of north-eastern India (Mizoram, Assam and Tripura) and Myanmar, based on morphological characteristics. The holotype comprises some skeletal elements held by the Natural History Museum of Vienna; the five paratypes consist of living specimens in the private collection of PP “Turtle Island” (a turtle conservation zoo in Graz, Austria). After the genetic identity had been determined in a previous investigation, the morphological description was carried out by examining living specimens and photo documents; and additionally, by evaluating the computed tomography of further living animals with exact location data. Amyda ornata jongli ssp. nov. differs from the other Amyda ornata subspecies mainly by its relatively compact and stout head in subadults and adults, its paler, greyish and less contrasting colouration missing distinct bright yellow pigments, ochre-coloured irises, and the existence of more distinct tubercles in the neck region and in the posterior section of the carapace than both other subspecies of Amyda ornata. The tubercles along the front of the carapace protrude clearly in subadult and adult specimens. This softshell turtle is heavily exploited within its limited distribution. Therefore, special comments on conservation aspects are given together with a final discussion on distribution and systematics.

DOI: 10.3897/herpetozoa.35.e78714

Authors: Rami Khashab, Daniel Jablonski

Abstract: We report the first record of the Diadem Snake, Spalerosophis diadema cliffordii (Schlegel, 1837) for Lebanon, based on an adult male found in the semi-desert area of the Beqaa Valley. This record increases the number of species of reptiles for Lebanon to 52, with the family Colubridae now comprising 17. The record also highlights the Beqaa Valley as a promising, but currently insufficiently investigated area for further herpetological research due to its biogeographic connection to the large semi-desert and desert areas of Syria.

A new species of bent-toed geckos of the genus Cyrtodactylus Gray, 1827 from western Arunachal Pradesh, India https://herpetozoa.pensoft.net/article/80610/ Herpetozoa 35: 65-76

DOI: 10.3897/herpetozoa.35.e80610

Authors: Zeeshan A. Mirza, Harshal S. Bhosale, Tejas Thackeray, Pushkar Phansalkar, Mandar Sawant, Gaurang G. Gowande, Harshil Patel

Abstract: A new species of bent-toed geckos of the genus Cyrtodactylus is described from western Arunachal Pradesh. The new species is a member of the Indo-Burma clade and is embedded within the “peguensis” group, a relationship deduced contingent on a partial fragment of mitochondrial NADH subunit 2 gene. Cyrtodactylus kamengensis sp. nov. is morphologically similar to C. himalayicus from which it differs in bearing a distinct ventrolateral fold and 6–8 basal lamellae on digit IV of pes. Genetically, the new species is sister to the Indian lineage of the “peguensis” group containing C. bhupathyi and C. gubernatoris. The Indian lineage of the “peguensis” group diverged from its Burmese relatives during the mid-Oligocene likely followed by the beginning of the Himalayan uplift, highlighting the role of the Himalayas in the diversification of biota.

Great capricorn beetle-created corridors as refuges for lizards https://herpetozoa.pensoft.net/article/81190/ Herpetozoa 35: 59-63

DOI: 10.3897/herpetozoa.35.e81190

Authors: Bartosz Borczyk, Iwona Gottfried, Radosław G. Urban, Jarosław Kania

Abstract: Ecosystem engineering is among the most important factors shaping ecosystems; however, it remains largely unstudied. Here, we present observations on three lizard species, the common lizard Zootoca vivipara, the sand lizard Lacerta agilis, and the slow worm Anguis fragilis, which use habitats created by the great capricorn beetle, Cerambyx cerdo. These galleries are heavily used by the common lizards and young sand lizards. We discuss the possible advantages of such beetle-created habitats for reptiles: antipredator refuges, hibernation sites, thermoregulatory behaviour, and preying activities. Since previous studies have reported numerous invertebrate species as well as vertebrates (including bats and snakes) in these refugia, we find the great capricorn beetle-inhabited oaks as potentially important microhabitats for a variety of animals.

DOI: 10.3897/herpetozoa.35.e80151

Authors: Shuo Qi, Jin-Long Ren, Zeng Wang, Hao-Cong Yang, Ke Jiang

Abstract: The genus Lygosoma Hardwicke & Gray, 1827 is a group of semi-fossorial supple skink from Southeast Asia, the members of which are still understudied in Indochina. Lysosoma quadrupes (Linnaeus, 1766) was once recorded from China based on historical literature; until recent its Indochina specimens were revised and placed into a newly described species, i.e., L. siamense Siler, Heitz, Davis, Freitas, Aowphol, Termprayoon & Grismer, 2018. However, Lygosoma quadrupes had long been unknown from China but the historical record had not been confirmed. Here we report a vouchered record for L. siamense from China for the first time based on four specimens collected in Sanya, Hainan, China. Furthermore, the taxonomic history of Lygosoma from China is also reviewed.

New records of Darevskia praticola at the northern limit of its distribution range in Romania https://herpetozoa.pensoft.net/article/79892/ Herpetozoa 35: 45-50

DOI: 10.3897/herpetozoa.35.e79892

Authors: Alexandra-Roxana-Maria Maier, Diana Cupșa, Sára Ferenți, Achim-Mircea Cadar

Abstract: In the summer of 2021 we identified three new distribution localities of Darevskia praticola north of the Mureș River, and one locality south of the river. The habitats populated by D. praticola (broad-leaved forest with wet areas) and the altitude (175–245 m) of the new records are typical for this species. Nevertheless, D. praticola had not been recorded in 12 other localities with similar conditions from an area previously considered suitable for this species. Thus, D. praticola may be slowly expanding from a bridgehead north of the Mureș River, occupying new favorable habitats. Probably, D. praticola recently crossed the Mureș River, possibly on a bridge, or with the timber trucks which exploit the woods from both sides of the river.

Abstract: Fluorescence is a poorly documented phenomenon in vertebrates and has been suggested to play several biological roles. With increased study, the number of species in which biofluorescence has been identified is increasing steadily. We conducted a UV light survey for biofluorescence in the herpetofauna in Lawachara National Park, Bangladesh and found biofluorescence in one amphibian (Microhyla berdmorei) and three reptile species (Boiga cyanea, Cyrtodactylus tripuraensis and Hemidactylus platyurus).

First record of ranavirus (Ranavirus sp.) in Siberia, Russia https://herpetozoa.pensoft.net/article/79490/ Herpetozoa 35: 33-37

DOI: 10.3897/herpetozoa.35.e79490

Authors: Artem P. Lisachov, Lada S. Lisachova, Evgeniy Simonov

Abstract: Ranaviruses are a group of double-strand DNA viruses that infect fish, amphibians and reptiles. These viruses are responsible for mass fish and amphibian mortality events worldwide, both in the wild and at fish and amphibian farms. The number of detected epizootics has grown significantly in recent years. In Eastern Europe and Northern Asia, including Russia, very few ranavirus monitoring studies have been conducted, in contrast with Western Europe and America. In the present work, we used a qPCR assay to survey for the first time the amphibian populations of West Siberia (Russia) for the presence of ranaviruses. In total, we studied 252 tissue samples from six amphibian species, collected across West Siberia from the south to the Arctic regions. We report a single infected sample: a common toad (Bufo bufo) captured near Tyumen city. The phylogenetic analysis showed that the detected virus strain belongs to the CMTV lineage. This is only the second observation of Ranavirus in Russia.

Abstract: The lowland populations of the viviparous lizard Zootoca vivipara in the Carpathian Basin occur in cold, marshy relict habitats. In one of the largest wetlands in Hungary, Kis-Balaton, in 2016 its presence was confirmed by catching an individual with a small mammal live-trap. This new record is significant, since the nearest known sites of occurrence are at great distance and it is situated between the lowland viviparous populations of the north-northeast and the oviparous populations of the south (in Croatia).

Abstract: This study presents the molecular phylogenetic relationships among Lytorhynchus diadema (Duméril, Bibron & Duméril, 1854) populations in Saudi Arabia relative to populations from Africa and Asia. This phylogenetic analysis was based on mitochondrial 16S and 12S rRNA partial gene fragments using Neighbor-joining, Maximum Parsimony, and Bayesian methods. The results strongly support the monophyly of Lytorhynchus based on two concatenated genes and the 12S rRNA gene separately. Also, a significant separation is observed between the Arabian samples from Saudi Arabia, Yemen, and Oman, and the African populations from Egypt, Tunisia, and Morocco.

Relationship between anuran larvae occurrence and aquatic environment in septentrional east Palearctic landscapes https://herpetozoa.pensoft.net/article/68577/ Herpetozoa 34: 265-270

DOI: 10.3897/herpetozoa.34.e68577

Authors: Amaël Borzée, Ye Inn Kim, Zoljargal Purevdorj, Irina Maslova, Natalya Schepina, Yikweon Jang

Abstract: The presence of amphibian larvae is restricted by both biotic and abiotic variables of the environment. Some of these variables are still undetermined in the septentrional eastern Palearctic where Rana amurensis, Strauchbufo raddei and Dryophytes japonicus are found in large numbers. In this study, we sampled 92 sites across Mongolia, Russia and the Democratic People’s Republic of Korea and measured biotic and abiotic water variables, as well as the height of flooded terrestrial and emergent aquatic vegetation at the breeding site. We determined that the presence of anuran larvae is generally, but not always, linked to pH and temperature. Rana amurensis was not significantly affected by any of the variables measured, while S. raddei was impacted by water conductivity and D. japonicus by pH, temperature and vegetation. Our results highlight a potential risk for these species due to the changes in aquatic variables in response to desertification.

Abstract: The European green toad, Bufotes viridis (Laurenti, 1768), is a rare and protected species in Vienna. In spring and summer 2020, we conducted a survey to assess size and status of its population in Donaufeld, an agricultural area designated for real estate development. Recaptures of photographically registered toads allowed to estimate the population size with 137 individuals (confidence interval: 104–181). Comparatively large body size indicates the presence of a well-established population. Reproductive success was high in the study year. A mismatch mating of a male B. viridis with a female Bufo bufo was observed. Mitigation measures are needed to support this population facing imminent habitat deterioration.

A partial molecular phylogeny of the Mexican species of snail-eating snakes (Serpentes, Dipsadidae) is presented, and we discuss evolutionary relationships as supported by our molecular results. We analyze specific relationships of the new species described herein with their closest relatives. We present a distribution map for all species of Tropidodipsas and include photographs of living individuals of each species. Finally, we discuss other taxonomic changes based on our molecular phylogeny as well as conservation priorities of the new species.

Finally, we comment on the conservation status of the species and the urgent need for additional studies. Besides discussing and reinterpreting published data, we provide new information from recent genetic studies, field activities and captive observations.

Choice of tree holes as oviposition sites by Kurixalus eiffingeri on Iriomote Island https://herpetozoa.pensoft.net/article/67271/ Herpetozoa 34: 201-205

DOI: 10.3897/herpetozoa.34.e67271

Authors: Taku Christopher Sato, Noriko Iwai

Abstract: Oviposition site choice affects survival and growth of offspring, particularly in frogs in which the offspring cannot move from the oviposition site. We intended to find the features of tree holes used for oviposition by Kurixalus eiffingeri on Iriomote Island. We measured eight tree hole variables to determine which should be included in the best model to explain breeding use by K. eiffingeri. Out of 32 tree holes examined, we found five that were used for oviposition. The best model included the height above the ground and angle of opening. Higher located tree holes and a larger opening angle were associated with more frequent oviposition by K. eiffingeri. This trend may be due to the higher predation risk in lower tree holes with a steeper opening. The importance of the height of the breeding site above ground was also noted in a previous study on bamboo stumps in Taiwan, but the opening angle was only salient in this study. Our study suggested that the same species in different ecosystems may use different criteria when choosing oviposition sites.

Anti-predator behaviour of Rhinella major (Müller and Hellmich 1936), with insights into the Rhinella granulosa group https://herpetozoa.pensoft.net/article/66909/ Herpetozoa 34: 195-200

DOI: 10.3897/herpetozoa.34.e66909

Authors: Fillipe Pedroso-Santos, Carlos Eduardo Costa-Campos

Abstract: In anurans, the different types of anti-predator behaviour have been documented in isolation, but some species have shown synergistic strategies in different situations. The display of these types of behaviour may be related to the types of predators in the habitat, which boost defensive responses in their prey. However, most reports are mostly opportunistic and punctual observations, not systematic. Here, we report the occurrence of anti-predator behaviour in the toad Rhinella major (Müller and Hellmich 1936) (Amphibia, Anura, Bufonidae) in the face of different handling modes. Probably the disturbance caused by handling had elicited a predator deterrence response in the individual, causing it to rapidly exhibit such behaviour. These conditions are discussed along with an overview of anti-predator behaviour in species of the R. granulosa group and we re-interpreted these strategies for two species in the group.

Phylogenetic relationships amongst the snake-eyed lizards of the genus Ablepharus Fitzinger, 1823 (Sauria, Scincidae) in the Iranian Plateau based on mtDNA sequences https://herpetozoa.pensoft.net/article/66338/ Herpetozoa 34: 183-194

DOI: 10.3897/herpetozoa.34.e66338

Authors: Rasoul Karamiani, Nasrullah Rastegar-Pouyani, Eskandar Rastegar-Pouyani

Abstract: We recovered molecular phylogenetic relationships amongst species of the genus Ablepharus in Iran and Iraq. Partial sequences of three mitochondrial genes (cytochrome C oxidase subunit I – COI, 12S rRNA and 16S rRNA) were analysed. In addition, phylogenetic relationships and taxonomic evaluation of Ablepharus species in Cyprus, India, Greece, Turkey and Syria were performed using partial sequences of the 16S rRNA gene. Phylogenetic trees and estimated genetic distances showed that the Ablepharus populations of Iran and Iraq clustered into three distinct clades. One is found in northwest Iran (A. bivittatus in Ardabil, East and West Azerbaijan and Hamedan Provinces). The second clade, formed by A. chernovi, is found only in Uromia. The third and most heterogeneous clade is divided into two subclades, the first includes two lineages of Ablepharus in Khorasan Razavi and Semnan Provinces (A. pannonicus) and in eastern and south-eastern Iran (A. grayanus); the second subclade is distributed in the eastern part of Iraq and west and south-western Iran (Ablepharus sp.). Our analyses indicated that splitting of A. chernovi within the genus occurred in the early Miocene [about 22.5 million years ago (Mya)]. Ablepharus bivittatus diverged 15.2 Mya, in the middle Miocene. Ablepharus pannonicus diverged in the late Miocene (8.4 Mya) and A. grayanus separated in the late Miocene (6.7 Mya). The lineages of eastern Iraq and south-western Iran (Ablepharus sp.) diverged also in the late Miocene (7.0 Mya).

Characterisation of a skin secretion with adhesive properties in the ground frog Eupsophus vertebralis (Alsodidae) https://herpetozoa.pensoft.net/article/68576/ Herpetozoa 34: 169-173

DOI: 10.3897/herpetozoa.34.e68576

Authors: Elkin Y. Suárez-Villota, Eliane Trovatti, Felipe A. Contreras, José J. Nuñez

Abstract: Some skin secretions with adhesive properties allow frogs to distract predators and escape; their nature is poorly studied. Here, we report the sticky skin secretion released by the Patagonian frog Eupsophus vertebralis when stressed. This secretion contained ~ 50% proteins spanning 25–250 kDa and required a fast setting time to turn into strong adhesive, which worked well on synthetic and biological materials. Lap-shear assays with Eupsophus glue secretion showed average shear strength of 3.34 MPa, comparable to cyanoacrylate (5.47 MPa). These properties suggest its biotechnological value for practical applications in industrial and medical sectors.

Effects of body temperature on initial bite force in three species of rock- and crevice-dwelling lizards from Mexico https://herpetozoa.pensoft.net/article/64040/ Herpetozoa 34: 163-168

DOI: 10.3897/herpetozoa.34.e64040

Authors: Guillermo A. Woolrich-Piña, Geoffrey R. Smith, Norberto Martínez-Méndez, Julio A. Lemos-Espinal, Héctor Gadsden-Esparza

Abstract: Bite force can be an important aspect of a lizard’s organismal performance, and is likely to be subject to influence by ambient conditions including an individual’s thermal environment. We examined the effects of body temperature (Tb) on initial bite force of rock- and crevice-dwelling individuals of three species of lizards: Abronia graminea (Anguidae), Barisia imbricata (Anguidae), and Xenosaurus fractus (Xenosauridae) from Mexico. In B. imbricata and X. fractus from one site (Xochititan, Puebla) initial bite force was greatest at intermediate Tb. In contrast, X. fractus from a second site (Tlatlauquitepec, Puebla) showed a weak tendency for initial bite force to increase with Tb. Initial bite force in A. graminea was not affected by Tb. Taking our results together, we infer that initial bite force in rock- or crevice-dwelling lizards is often, but not always, related to Tb.

Lurking in the depth: Pond depth predicts microhabitat selection by Rhinella icterica (Anura: Bufonidae) tadpoles at two different sampling scales https://herpetozoa.pensoft.net/article/56326/ Herpetozoa 34: 149-158

DOI: 10.3897/herpetozoa.34.e56326

Abstract: Habitat selection has long been a central theme in ecology and has historically considered both physiological responses and ecological factors affecting species establishment. Investigating habitat selection patterns at different scales can provide important information on the relative roles of the environmental factors influencing the organisms’ abilities to use their surrounding habitat. This work aimed at investigating which environmental factors determine habitat selection by Rhinella icterica tadpoles, and also took the opportunity to investigate how the scale in which tadpoles and environmental data are sampled might influence the habitat selection results. A total of 2.240 tadpoles were counted in the whole sampling area, and while substrate cover and depth were the variables that better explained the abundance of tadpoles at the larger scale (plot level), depth and water turbidity better explained tadpoles’ abundance at the smaller scale (subplot level). The results suggest that avoiding predation by matching the background color is a likely process explaining tadpoles’ occupancy at both scales. Depth is known to influence tadpole habitat use in the tropics, and although its combination with turbidity and substrate cover varied between scales, our study suggests that sampling at different scales might not affect the inferred ecological processes driving habitat selection. This information might also be useful to predict tadpoles’ responses to micro-environmental perturbations and help in guiding the choice of parameters that should be taken into account when analyzing the effects of habitat degradation in Atlantic Forest amphibian populations.

The genus Pelophylax (Amphibia, Ranidae) in Pakistan: museum collections and possible distribution https://herpetozoa.pensoft.net/article/64955/ Herpetozoa 34: 141-147

DOI: 10.3897/herpetozoa.34.e64955

Authors: Daniel Jablonski, Addison Wynn, Rafaqat Masroor, Theodore Papenfuss, Spartak N. Litvinchuk, Glib Mazepa

Abstract: We provide the first comprehensive data on the questionable distribution of the genus Pelophylax and the family Ranidae from Pakistan. Based on a literature review and two specimens of the genus from Tasp, Panjgur District in Pakistani Balochistan (USNM 26194–95), stored in the Smithsonian National Museum of Natural History, Washington, DC, USA, we discuss the possible occurrence and affiliation of these frogs in the context of Central Asia. Our comparison shows that the nearest records of Pelophylax in relation to the Tasp specimens are reported from more than 280 km (air-line) away in Iran and Afghanistan, which are currently separated by hot and mostly desert environments. We suggest that possible surviving populations of this genus may still be present in Balochistan (Rakhshan River) or Khyber Pakhtunkhwa (Kabul River) Provinces of Pakistan. This would, however, need further field investigations.

DOI: 10.3897/herpetozoa.32.e69755

Authors: Shuo Liu, Mian Hou, Mingzhong Mo, Dingqi Rao

Abstract: A new species of the genus Micryletta Dubois, 1987 is described from Yunnan Province, China, based on morphological and molecular analyses. The most obvious differences between the new species and other species of this genus are small body size, unique coloration, and relatively longer hind limbs. In 16S rRNA gene sequences, the new species is diverged from all other congeners by 3.1%–8.0%.

Abstract: Herein, we report the first observation of two different coloration patterns in Chilean snakes. Based on the alteration of wild coloration patterns, a juvenile specimen of Tachymenis chilensis coronellina Werner, 1898 was diagnosed with albinism and a juvenile specimen of Tachymenis chilensis chilensis (Schlegel, 1837) was diagnosed with leucism. The existence of color variations in wild snake populations and the implications of these for fitness are discussed.

Females of the four-eyed frog, Pleurodema thaul (Anura, Leptodactylidae), respond behaviourally to conspecific male scent https://herpetozoa.pensoft.net/article/62007/ Herpetozoa 34: 115-120

DOI: 10.3897/herpetozoa.34.e62007

Authors: Valentina Rojas, Antonieta Labra, José Luis Valdés, Nelson A. Velásquez

Abstract: Among amphibians, conspecific chemical communication has been widely studied in Caudata. Adult anurans, by contrast, have received less attention. Recently, it was shown that chemical scents are also relevant for adult anuran intraspecific communication. In this context, we evaluate whether females of the four-eyed frog (Pleurodema thaul) respond to conspecific male scents. We carried out a double choice experiment in a Y-maze. Females were repeatedly presented with the scents of several males versus distilled water. To extract the scent from males, we acoustically stimulated males and then used the water from their aquaria for the experiments. Our data suggest that females are capable of responding behaviourally to male scents, since they spent longer periods in the zones with male scent, rather than in zones with water. We propose that under natural breeding conditions, females of P. thaul may use either their chemical sense or chemical cues to facilitate their encounters with males.

The first comprehensive data on the distribution of reptiles within the Southern Bug eco-corridor, Ukraine https://herpetozoa.pensoft.net/article/62459/ Herpetozoa 34: 97-114

DOI: 10.3897/herpetozoa.34.e62459

Authors: Oleksandra Oskyrko, Daniel Jablonski

Abstract: This study provides distribution data for 12 species of reptiles in the Southern Bug eco-corridor located within the steppe zone, Mykolaiv Oblast (province), Ukraine. We compiled 935 records from published literature (324), from public databases (68), and from 12 field surveys we made in 2016–2020 (543). All records were mapped on to a grid of 10×10 km, representing the 294 cells of the studied area. We present new distributional data for Podarcis tauricus. For all the other species, our records add new localities that fall within areas where these reptiles were previously reported. Species richness and Shannon’s H’ index show that herpetofauna diversity was higher in the areas along the Southern Bug River. The maximum number of records within a single cell was 118 (for 10 species) in this oblast. Also the high number of identified reptile chorotypes (nine) within the Mykolaiv Oblast revealed that southern Ukraine is an important zoogeographical territory in Europe. These data provide the basis for future biogeographical and ecological studies and conservation priorities.
