Trimeresurus jerdonii is a venomous pit viper species endemic to India (Assam), Burma, Tibet, China and Vietnam. Three subspecies are currently recognized, including the nominate subspecies described here.[5]
Etymology
The specific name, jerdonii, is in honor of British herpetologist Thomas C. Jerdon who collected the type series.
Description
Males grow to a maximum total length of 835 mm (32.9 in), with a tail length of 140 mm (5.5 in); females to 990 mm (39 in), with a tail length of 160 mm (6.3 in).[6]
Scalation: dorsal scales in 21 longitudinal rows at midbody (rarely 23); snout length a little more than twice diameter of eye; head above, except for large internasals and supraoculars, covered by small, unequal, smooth scales that are feebly imbricate or juxtaposed; first labial completely separated from nasal scales by a suture; internasals separated by 1-2 small scales; 6-9 small scales in line between supraoculars; 7-8 upper labials, third and fourth beneath eye, in contact with subocular or separated by at most a single series of small scales; ventrals: males 164-188, females 167-193; subcaudals: males 50-78, females 44-76.[6]
Geographic range
Found from Assam in India, through northern Burma to Tibet, China (Hupeh, Szechwan, and Yunnan), and Vietnam. The type locality given by Günther is "Khassya" (=Khasi Hills, India).[1]
