It is, along with the other species in its genus Chrysopelea, very unusual in that it is capable of a type of gliding flight. It is also rear-fanged. Currently, three subspecies are recognized.

Ahaetulla, commonly referred to as Asian vine snakes or Asian whip snakes, is a genus of colubrid snakes distributed throughout tropical Asia. They are considered by some scientists to be mildly venomous and are what is commonly termed as 'rear-fanged' or more appropriately, opisthoglyphous, meaning their enlarged teeth or fangs, intended to aid in venom delivery, are located in the back of the upper jaw, instead of in the front as they are in vipers or cobras. As colubrids, Ahaetulla do not possess a true venom gland or a sophisticated venom delivery system. The Duvernoy's gland of this genus, homologous to the venom gland of true venomous snakes, produces a secretion which, though not well studied, is considered not to be medically significant to humans.
Craspedocephalus 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.
Boiga barnesii is a species of cat snake endemic to Sri Lanka. It is known as Barnes' cat snake in English and panduru mapila-පදුරු මාපිලා in Sinhala. It is a member of the snake family Colubridae.

Proposed vernacular names for D. sinharajensis include Sinharaja tree snake, Sinharaja haldanda, and Sinharaja komberi muken (Tamil).
The Ahaetuliinae are a subfamily of the snake family Colubridae that was erected in 2016 and comprises five genera containing 63 species that are more closely related to one another than to members of the subfamily Colubrinae. Previously placed within Colubrinae, Ahaetuliinae was strongly supported as the sister group to Colubrinae in a 2016 study by Figueroa et al.
