Order : PRIMATES
Family : Cercopithecidae
Species : Trachypithecus selangorensis

Head-body length : 41-54 cm
Tail length : 60-76 cm
Weight : 4.0-6.5 kg

The Selangor Silvered Langur inhabits coastal and riverine habitats on the west coast of Peninsular Malaysia.

This species is still considered by some primatologists to be simply a mainland subspecies  of the widespread Silvered Langur Trachypithecus cristatus, which occurs on some of the larger islands of Southeast Asia, such as Sumatra and Borneo. However, it is now treated by other primatologists as a separate species in its own right (Roos et al, 2014).

It is virtually identical in appearance to the Silvered Langur, with dark grey fur with a silvery sheen, and with the skin on the face, hands and feet being black. The young are bright orange in colour, like those of the Silvered Langur.

The Selangor Silvered Langur is restricted to the west coast of Peninsular Malaysia, from Kedah in the north to Johor in the south. There are no records from Singapore, either historical or recent, which lies at the very tip of the malay peninsula.
