Salazar's pit viper is a venomous green pit viper first discovered in 2019 in the lowlands of the western part of Arunachal Pradesh, the fifth new reptile species discovered in the region that year. It has a long, thin body reaching 363 to 415 mm, with a triangular, elongated head clearly distinct from the neck, a dark green head and yellowish-green back (Wikipedia, general species account).
The sexes differ: males have reddish-orange and yellow-orange stripes and a rusty red-orange tail that females lack. It is nocturnal and has been observed coiled on shrubs at night. Pit vipers of the genus Trimeresurus eat lizards, amphibians, birds, rodents and other small mammals. Its habitat is under threat from human development.
