The Selangor silvered langur[1] (Trachypithecus selangorensis) is a leaf monkey living on the west coast of the Malay Peninsula.
- Previously, it was considered a species of silvery Lutung. Roos and his colleagues elevated this population to a subspecies, Trachypithecus cristatus selangorensis, in 2008.
- Since then, primatologists have considered it a separate species, Trachypithecus selangorensis.
- The Selangor silvered langur has a gray body while the face, feet and hands are black. The type specimen had a head and body length of 50.6 centimeters (19.9 in) and a tail of 70.4 centimeters (27.7 in).
- The closely related Silvery Lutung has an average head and body length of 48.9 cm (19.3 in) for females and 54.4 centimeters (21.4 in) for males.
- The Silvery Lutung weighs an average of 5.7 kilograms (13 pounds) for females and 6.6 kilograms (15 pounds) for males.
- The Selangor silvered langur differs from the silvery langur in the shape of its whiskers. The Selangor silvered langur has long, straight whiskers, while the silvery Lutung has scalloped whiskers. The two species also differ genetically.
