Habitat
Semi-arboreal; nocturnal

South-east Asia and surrounding countries, including India, Bangladesh and southern China
The mountain slug snake is found across much of South-east Asia and surrounding countries, including India, Bangladesh, Myanmar, Thailand, Laos, Vietnam, Malaysia and southern China. It is ochre brown to red-brown with somewhat net-like bars formed by two-toned scales, white in front and deep claret brown behind, giving a half-banded, half-spotted look, and the belly is brown, spotted and mottled (Wikipedia, general species account).
Like others in its genus it is a nocturnal, semi-arboreal snail and slug specialist, and lays eggs. The Reptile Database lists Darjeeling, Sikkim and West Bengal with a query.
