Revised diagnosis. Cryptelytrops macrops s.s. is distinguished from all other Asian pitviper species which also have the typical "green pitviper" colouration (uniform green dorsal colour and a lateral stripe present on the first few dorsal scale rows in one or both sexes), except other species of Cryptelytrops, by the presence of a fused first supralabial and nasal scale. It can be distinguished from C. albolabris, C. insularis and C. septentrionalis primarily by the relatively larger size of the eye (most obvious in adults), the relatively wider supraoculars, and the shape of the head, which is more elongate–oval in C. albolabris, C. insularis and C. septentrionalis, but widens quite abruptly behind the eyes in C. cardamomensis sp. nov., C. macrops s.s. and C. rubeus sp. nov. to give a character- istically triangular shaped head. Cryptelytrops macrops s.s. can be distinguished from both C. cardamomensis sp. nov. and C. rubeus sp. nov using the characters detailed above (further details are also given in Tables 2 and 3) [from MALHOTRA et al. 2011].
