It has since come to be regarded by primatologists as a separate species, Trachypithecus selangorensis. == Description == The Selangor silvered langur has a gray body with a black face and black feet and hands. The type specimen had a head and body length of 50.6 centimetres (19.9 in) and a tail that was 70.4 centimetres (27.7 in) long.
