Description

Total length males 600 mm, females 810; tail length males 120 mm, females 130 mm.[3]

Head scalation consists of 10-11(12) upper labials, the first partially or completely fused to the nasal. Head scales small, subequal, feebly imbricate, smooth or weakly keeled. The supraoculars are narrow, occasionally enlarged and undivided with 8-12 interocular scales between them. Temporal scales smooth.[3]

Midbody has 21 (rarely 19) longitudinal scale rows. The ventral scales are 155-166 in males, 152-176 in females. The subcaudals are paired, 60-72 in males, 49-66 in females. The hemipenes are without spines.[3]

Color pattern: green above, the side of the head below the eyes is yellow, white or pale green, much lighter than rest of head. The belly is green, yellowish or white below. A light ventrolateral stripe is present in all males, but absent in females. The end of tail is not mottled brown.[3]

Taxonomy

Giannasi et al. (2001) raised insularis and septentrionalis to species level.[4][6] Malhotra & Thorpe (2004) transferred this species (and a number of others) to the genus Cryptelytrops.[7]
