The black-crested Sumatran langur[1] (Presbytis melalophos), also called the Mitred leaf monkey, is a primate species in the Cercopithecidae family.
- Its natural habitat is tropical or subtropical dry forests. Like all members of the Presbytis genus, black-crested Sumatran langurs have short snouts and poorly developed eyebrow ridges.
- They have long front legs and relatively long hind legs, consistent with their preferred mode of locomotion, jumping, and brachiation.
- These Asian primates are distinguished from other Presbytis species by their monophasic call, coat character, and skull features such as narrow interorbitals and long nostrils.
- Presbytis melalophos has a gray-brown coat with the underside lighter than the back. The tail is bi-colored, and the head has a distinctive black crest.
