Tropidolaemus huttoni

Hutton's pit viper is a pit viper endemic to the southern Western Ghats of India. The coloration and size of adults are unknown. Juveniles are green above with a series of small white spots on both sides, and a distinct red streak behind each eye (Wikipedia, general species account).

It is known from a plateau on the western central edge of the Varushanad Hills, at about 1,590 m, in Theni district of Tamil Nadu. A possible third specimen from the northern Western Ghats is considered of doubtful identity, so the species is known from very few animals.
