Trimeresurus davidi

Trimeresurus davidi is a medium to large pit viper recently described from Car Nicobar in the Nicobar archipelago, with body lengths from 277 to 835 mm. The name honours herpetologist Patrick David, who contributed to the taxonomy of Asian pit vipers and the Nicobar herpetofauna (Wikipedia, general species account).

It has 21–25 rows of back scales at midbody, 166–179 belly scales and 58–70 under-tail scales, a partly fused nasal and first upper lip scale, a single scale before the eye and 2–3 behind it. It lives in trees.
