Dendrelaphis caudolineatus (JE Gray, 1834)

Dendrelaphis caudolineatus, commonly known as the striped bronzeback or grey bronzeback, is a species of colubrid snake found in Southeast Asia.

Etymology

When John Edward Gray first scientifically described the species in 1834, he did not provide the origin of the scientific name caudolineatus. However, in Latin "cauda" means tail and "linea" mean line, possibly referencing the longitudinal lines reaching from head to tail.

Taxonomy

Dendrelaphis caudolineatus belongs to the genus Dendrelaphis, which contains 48 other described species. Prior to a 2012 study, several other species of Dendrelaphis were previously considered to be members of Dendrelaphis caudolineatus, but are now considered to be separate species: D. flavescens, D. terrificus, D. philippinensis, and D. levitoni.

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:

Ahaetuliinae	sharp‑nosed snakes Ahaetulla Proahaetulla Dryophiops broad‑nosed snakes Dendrelaphis Dendrelaphis marenae Dendrelaphis haasi Dendrelaphis pictus Dendrelaphis ngansonensis Dendrelaphis cyanochloris Dendrelaphis striatus Dendrelaphis formosus Dendrelaphis tristis Dendrelaphis subocularis Dendrelaphis schokari Dendrelaphis fuliginosus Dendrelaphis caudolineatus Chrysopelea

Distribution

Dendrelaphis caudolineatus is found in Malaysia, Thailand, Indonesia, Brunei, and Singapore.

Habitat

It is found in a wide variety of forested habitats, commonly seen in trees and bushes, most often near swamps and streams. It can be found in gardens and cultivated areas. It is widespread, and one of the most commonly seen snakes in its range.

Dendrelaphis caudolineatus is a rather small and thin snake, it can reach a length of 180 centimeters but is usually closer to 140 cm. The males are usually thinner than females but are more colorful, ranging from a reddish shade or bright chestnut brown, to a shiny bronze color. The females are usually dull-colored, and more stout-bodied than the males. It is also observed that females of this species tend to be less active than the males.
