Protobothrops kaulbacki, commonly known as the Kaulback's lance-headed pitviper [3] or Kaulback's lance-headed pit viper, [1] [4] is a venomous pit viper species endemic to Asia. No subspecies are currently recognized. [3] [5]
The specific name, kaulbacki, is in honor of British explorer Ronald Kaulback. [3] [6] [7] [8]
Adult males of P. kaulbacki 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]
Protobothrops 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 also from Tibet (China). [1] [10] It also occurs in Arunachal Pradesh (NE India). [3]
Protobothrops kaulbacki 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). Each hatchling is 26–27 cm (about 10½ inches) in total length. [9]

Ovophis monticola is a venomous pitviper species found in Asia. Currently, two subspecies are recognized, including the nominate subspecies described here. Recent taxonomic work suggests that most of these should be considered as separate species. IUCN has already evaluated O. m. makazayazaya as Ovophis makazayazaya.
Protobothrops jerdonii is a venomous pit viper species found in India, Nepal, Myanmar, China, and Vietnam. Three subspecies are currently recognized, including the nominate subspecies described here.

Protobothrops mangshanensis, commonly known as the Mangshan pit viper, Mangshan pitviper, Mt. Mang pitviper, or Mang Mountain pitviper, is a venomous pit viper species endemic to Hunan and Guangdong provinces in China. No subspecies are currently recognized. This is a nocturnal pit viper that is also known as the ''Mangshan iron-head snake'', ''Chinese pit viper'', and the ''Ironhead viper''. They eat frogs, birds, insects, and small mammals. They have a white tail tip that they wiggle to mimic a grub so that prey comes into striking range—a behaviour known as caudal luring. The venom causes blood clotting and corrodes muscle tissue and can kill people. Unusually for vipers, P. mangshanensis is oviparous with the female laying clutches of 13–21 eggs which she will guard until they hatch.
Trimeresurus trigonocephalus, the Sri Lankan pit viper, Ceylon pit viper, Sri Lankan green pitviper or locally, pala polonga, is a venomous pit viper species endemic to Sri Lanka. No subspecies are currently recognized.

Gloydius strauchi is a species of venomous pit viper in the subfamily Crotalinae of the family Viperidae. The species is native to western China. It is a small snake with a pattern of four longitudinal stripes, although some older specimens may be a uniform black. G. strauchi may be distinguished from G. monticola by its higher midbody dorsal scale count. This species jointly holds the altitude record for pitvipers together with Crotalus triseriatus of Mexico, both being found even above the tree line at over 4,000 m (13,000 ft). No subspecies were recognized as being valid, until a recent publication re-evaluated the taxonomic statuses of populations of G. strauchi and described the eastern Tibetan populations as a new species.
