Dendrelaphis is a genus of colubrid snakes, distributed from Pakistan, India and southern China to Indonesia, Timor-Leste, the Philippines, Australia, New Guinea and the Solomon Islands. There are over forty described species. Asian species are known commonly as bronzebacks, while the Australo-Papuan species are simply called treesnakes. All are non-venomous and entirely harmless to humans.

Taxonomy

[edit]

Dendrelaphis is one of five genera belonging to the vine snake subfamily Ahaetuliinae, of which Dendrelaphis is most closely related to Chrysopelea, as shown in the cladogram below:[1]

Ahaetuliinae

Species

[edit]

This list is based on the latest checklist of snakes in the world[2] and recent revisions and descriptions published in the scientific literature.

The authors of a 2015 revision of the Australo-Papuan Dendrelaphis species recommended the synonymy of D. solomonis within D. calligaster, the elevation of D. keiensis to species status, the resurrection of D. lineolatus from within D. calligaster, and the resurrection of D. macrops and elevation of D. striolatus from within D. punctulatus. They also confined D. punctulatus to Australia and D. papuensis to the Trobriand Islands of Papua New Guinea.[3]

Description

[edit]

Bronzebacks range in total length (including tail) from 2 feet (0.61 m) to up to 6 feet (1.8 m). All species have a slender body with a long tail. Males are shorter in length and brighter in coloration; they also tend to be more active. Females are stouter with duller or darker colorations and are less active. Typical coloration includes red, brown, or orange on the head with bronze, brown, or olive-green running down the length of the back. The underside of the body is usually bright to pale green or yellow. They have big eyes and bright red tongues. The tail is fully prehensile.

Diet

[edit]

The primary prey of Dendrelaphis species consists of lizards and frogs, but the larger species are capable of taking birds, bats, and small rodents.
