The specific name, leucomystax, is Greek for "white mustache.
This snake, though primarily an upland species, is associated with both lowland and montane evergreen monsoon forests. It can be found near streams in mixed dipterocarp and pine forests. More rarely, it has been found in secondary forest. Its diet includes frogs and other small animals.
They grow to 406mm in snout–vent length and 595mm in total length. It has a beautiful yellow-white stripe that sweeps along its head, and red dots cover its body.[1]
