No pronounced sexual dimorphism in colour and pattern, but females tend to have slightly lighter snout. The dorsal pattern can sometimes be united to a narrower or broader zig-zag band, but consists most frequently of separated light, often round blotches that sometimes, and especially on lateral sides, are dark-edged with dark brown or blackish. The number of blotches is ranging from 34 to 46 (^T = ). A series of akernating dark spots on lateral side of body. Neck pattern as in diagnosis. Belly blackish. On top of head two large supraoculars, which are separated from eye by circumocular scales. The outer edge of the supraoculars is protruding in right angle, giving an appearance of a small horn or markedly raised eyebrows. The supraoculars are separated from each other by 6 to 9 (?r = ) interocular scales at shortest distance. Total number of intersupraocular scales is 22 to 35 (x" = ). The number of canthals on each side separating supraocular from supranasal varies between and (?r = ). Two to five (x = ) apicals bordering rostral. The number of intercanthals is 11 to 24 (x = ), and with a total number of scales on top of head (intercanthals + intersupraoculars) of between 36 and 52 (x = ). Eye separated from supralabials by two subocular rows and surrounded by a complete first inner circumocular ring, containing 12 to 18 (^T = ) scales and by an outer ring, containing 13 to 18 (x = ) scales. Nostril in the middle of a big nasal shield, which is partly fused with the prenasal. Upper preocular separated from the nasal by a loreal. Nine, or more rarely ten {x = ) supralabials, and ten to fourteen (x = ) sublabials on each side. Two large anterior chinshields, followed by 4 to 6 ()r = ) posterior chinshields. 2 to.
