CommentDiagnosis. Montivipera kuhrangica sp. nov. can be distinguished from other known taxa of the Montivipera raddei group by a combination of meristic and color-pattern characters. In meristic point of view, it can be stated that the new viper has a relatively high fragmentation and as a result high count of head scales compare to other taxa of the Montivipera raddei species group. In addition also strongly projected supraoculars. As is shown in Table 1, Montivipera kuhrangica sp. nov. has higher number of head scales than average in other known taxa, e.g., in intercanthal scales, supralabial and infralabial scales and outer circumocular scales, as well as highest number of intersupraocular rows of scales.

In addition the shape of dorsal zigzag blotches in Montivipera kuhrangica sp. nov. is different than other mountain vipers. The dorsal blotches are mostly not tri- angle or rounded but instead often square-shaped. Also toward hind dorsum, there is a tendency to fusion of dorsal blotches to form a straight vertebral line in this new viper. In the Holotype this fusion only has occurred on tail and in the second specimen the fusion of the dorsal blotches can be seen in posterior third of dorsal side of body [from RAJABIZADEH et al. 2011].
