 In females the belly is greyer, while in males it is almost black with some white fragments on the edges of the ventral scales.The chin shields and labial scales are white, with few dark fang-shaped markings on the labials, which makes this species different from the related "Vipera eriwanensis", which has a somewhat pink tint on the labials.In general adult males are noticeably brighter and have more color contrast compared to females.
