The colubrid snake genus Dendrelaphis comprises of 45 species (Uetz et al. 2018) of which eleven currently occurs in India (Aengals et al. 2018). A member of this genus, Dendrelaphis caudolineatus (Gray, 1834), was once considered a wide-ranging species in Southeast Asia, the Philippines and the Indo-Australian Archipelago, until Van Rooijen Vogel (2012) resolved taxonomy of this species complex. Now its range is restricted from southern Thailand to Sundaland (Peninsular Malaysia, Sumatra, Billiton and Borneo; presence doubtful in Java of Indonesia) (Van Rooijen Vogel 2012).
