Selangor silvered langur

The Selangor silvered langur, Trachypithecus selangorensis, is a leaf monkey found on the west coast of Peninsular Malaysia. It had been considered a form of the silvery lutung until Roos and colleagues raised the population to subspecies rank in 2008, and primatologists have since regarded it as a separate species. It has a gray body with a black face and black hands and feet; the type specimen had a head and body length of 50.6 cm and a tail of 70.4 cm. It differs from the silvery lutung in having long, straight whiskers rather than mussel-shaped ones, and the two differ genetically. Infants are born bright orange with white faces, hands and feet and take on adult colouring over the first 3 to 5 months, and all group members help care for them. The English Wikipedia list of Old World monkeys records it as near threatened.
