Phylogenetic tree resulting from a Maximum Likelihood (ML) reconstruction based on 604 base pairs of the Cytb sequence. The black box with dotted lines represents the individuals from central Zagros. Other samples originate from the study Oraie et al. (2018). Bootstrap support values from maximum likelihood analysis are indicated at the nodes. The tree was rooted using Montivipera raddei and Montivipera xanthina as out-groups.
