| Diagnosis | Diagnosis: the new species is assigned to the subgenus Trimeresurus based on the following morphological attributes: a long calyculate hemipenis and a partially fused first supralabial and nasal scales (Malhotra & thorpe 2004 [as Cryptelytrops]; David et al. 2011). the new species Trimeresurus cryptographicus sp. nov. differs from other members of the subgenus Trimeresurus by the combination of the following morphological characters: small size, maximum known SVl of 523 mm; dorsal scales in 23(22)-21-15 rows, moderately keeled except the outermost rows; ventral scales 171–178; subcaudal scales 57–73 (sexes pooled), all paired; iris golden yellow in both sexes; body uniformly bright grass-green with indistinct serrated dark transverse markings in adults (SVl 499–523 mm), but neonates and juveniles (SVl 231–245 mm) have prominent irregular serrated darkgrey crossbands on a light green dorsum; suborbital stripe bluish-white and thin in male, absent in females; ventrolateral stripe white, distinct, present on the first few dorsal scale rows in both sexes; throat, chin, and lower labials pale blue; ventral surfaces greenish-yellow; tail light brick-red mottled with dark spots above, and with white markings below.
