[edit] Description
Total length males 610 mm, females 730 mm.[3]
The head scalation consists of 10-11(12) upper labials, the first of which are fused to the nasal. The head scales are small, subequal and feebly imbricate, smooth or weakly keeled. The supraoculars are narrow and undivided with 9-11 interocular scales between them. The temporal scales are smooth.[3]
Midbody there are 21 longitudinal scale rows. There are 1162-172 ventrals in males, 160-181 in females. The subcaudals are paired and number 68-83 in males, 55-71 in females. The hemipenes are without spines.[3]
The color pattern is green above. The belly is green, yellowish or white below. A faint ventrolateral stripe present in all males, but absent in females. The end of tail not mottled brown.[3]
Holotype: MHNG 1404.31[3]
