The Hatinh langur has a black body and a white stripe running from the cheeks toward the neck. By day it feeds in forest trees and rests at night in limestone holes and caves.
Its body and tail are glossy black. A band of white fur runs from the cheeks behind the ears to the nape, and a spiky tuft crowns the head.
It is diurnal and arboreal, eating mostly leaves as well as some fruit. At night it rests in limestone caves or crevices, with adults tending to use separate sleeping places.
