Ahaetulla isabellina,[1][2] also known as Wall's vine snake,[3] is a species of tree snake endemic to the southern Western Ghats of India .[1][2][3][4]

Taxonomy

It was formerly considered a subspecies of A. nasuta, which is now considered to only be endemic to Sri Lanka. A 2020 study found A. nasuta to be a species complex of A. nasuta sensu stricto as well as A. borealis, A. farnsworthi, A. isabellina, and A. malabarica, elevating A. isabellina to species. The specific epithet is a reference to the isabelline yellow coloration of the species' dorsal body in live condition, which distinguishes it from other species in the complex.[2]

Habitat

This species is found in evergreen forests of the Western Ghats from ~550 m to 1475 above sea level.[2]
