Dorsal view of the head of the holotype of Vípera wagneri sp. n. It differs from V. raddei and allied populations in Iran and from V. latifii in the absence of a complete circumocular ring, which in these taxa separates eye from supraocular, in having a single canthal on each side, in lacking erected supraocular plates, in a different pattern and in a much lower number of sub- caudal plates. From V. raddei it also differs in having a lower number of ven- trals. Description of holotype: A young female with a total length of 291 mm and tail of 21 mm. Head covered by small scales except enlarged supraocular plates, which are separated from each other by six interocular scales. One canthal be- tween supraocular and supranasal on each side and two apicals in contact with rostral. Fourteen intercanthals and 29 intersupraocular scales on upper surface of head. Supraoculars not raised and in broad contact with eye. Two subocular rows. First circumocular ring (except supraoculars) containing 15 and 14 scales on right and left side of head respectively. Second distal circumocular ring con- tains 14 and 16 scales on right and left side respectively. Nine supralabials on each side and 13 and 12 sublabials on right and left side respectively. Three pre- ventrals followed by 161 ventrals and a single anal plate. Subcaudals in 24 and.
