The Laotian wolf snake is a non-venomous colubrid endemic to Asia. It is dark brown above with a whitish or yellowish crossband on the back of the head and similar body crossbands that fork on the sides, and whitish below. Adults are about 0.5 m long including a tail of about 10 cm. Like other wolf snakes it can be mistaken for the venomous banded kraits (Wikipedia, general species account).
It is nocturnal and generally ground-dwelling, not very aggressive and generally reluctant to bite. The Reptile Database lists India but the account used here does not say where in India.
