Kanburi Pit Viper

Adults grow to more than 76 cm (30 in) in length and are heavily built. The maximum length is unknown. Scalation includes 19 rows of dorsal scales at midbody, 159 ventral scales, 42 subcaudal scales and 10 supralabial scales, the third being the largest. The color pattern varies from brown with faint patterning to tawny with dull brown blotches and spots along with a ventrolateral stripe. This species, especially the population in the south, which was formerly referred to as T. venustus and recently shown to be a separate species, has often been confused with the mangrove pit viper, T. purpureomaculatus. However, the two are easily distinguished by the first three supralabial scales, which are much enlarged in T. kanburiensis.

Found in Thailand. The type locality given is "limestone hills near Kanburi, south-western Siam" (= Kanchanaburi, Kanchanaburi Province, Thailand). Listed as "S.W. China" in the catalogue entry at the British Museum of Natural History. Known only from two other areas near the type locality, as well as from the type locality given in Vogel (1991) for T. venustus, which is "Thung Song, Provinz Nakhon Si Thammarat, Süd-Thailand".

Arboreal and nocturnal, although they have been reported basking during daylight hours. Retreats to seek shelter in the foliage during the heat of the day.
