The crying keelback had to be compared with 44 species of snakes worldwide under the genus Hebius. “I had data on 20 species of this genus. So I collaborated with Patrick David of the Paris-based National Museum of Natural History who had data on another 22,” Purkayastha said.
According to the paper by Purkayastha and David, the crying keelback can be differentiated from all other species of the genus Hebius by the combination of a distinctive broad, white, interrupted stripe along its body; three rows of irregular dark blotches (not vertically aligned) on each side; six cream, elongated spots on its anterior part and a smooth dorsal scale row.
The snake, prefers to live near streams along paddy fields and was found to feed on small fish, tadpole, frogs and geckos.
Globally snakes are represented by 3,709 species. The northeast is home to some 110 species, with Arunachal Pradesh accounting for 55.
