Protobothrops kaulbacki is a venomous pit viper species endemic to Asia. No subspecies are currently recognized.[5]

Etymology[edit]

The specific name, kaulbacki, is in honor of Ronald Kaulback.[6][7][8]

Description[edit]

Adult males may attain a total length of 134 cm (53 in), which includes a tail 22.5 cm (8.9 in) long. Females may grow longer: maximum total length 141 cm (56 in), tail 23 cm (9.1 in).

Dorsally, it is green, with a vertebral series of dark angular spots, which may be joined to form a zigzag stripe. The top of the head is black with yellow stripes. Ventrally, except for the whitish throat area, it is gray with large squarish or crescent-shaped yellow spots.[9]

Scalation includes 25 rows of dorsal scales at midbody, 201-212 ventral scales, 66-78 subcaudal scales, and 8 supralabial scales of which the third is the largest.[4]

Geographic range[edit]

P. kaulbacki had originally been known only from the type locality, which is "Pangnamdim, north of the Triangle, Upper Burma" (Myanmar).[2] In 2005 it was reported that it is also found in China.[10] Recently, this species is reported from Northeast India. Currently, It is known from single location in India at Dafla Hills in Papum Pare District, Arunachal Pradesh, Northeast India.

Reproduction[edit]

This species is oviparous. The adult female lays a clutch of 6-32 eggs in a hole in the ground, and then remains with the eggs to guard them. Eggs measure 48–53 mm x 26–27 mm (about 2 in x 1 in). The hatchlings are 26–27 cm (about 10½ inches) in total length.[9]
