The black-crested Sumatran langur (Presbytis melalophos) is a species of primate in the family Cercopithecidae. It is endemic to Sumatra in Indonesia. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss. ^[1]

The black Sumatran langur, black-and-white langur, Sarawak surili, Raffles' banded langur and mitered langur were formerly considered subspecies of P. melalophos. ^{[2] [3]}

Diet

Black-crested Sumatran langurs are frugivorous and folivorous. With fruit making up 50 to 60 percent of their diet, the rest consists of leaves and occasionally seeds and flowers. Their foregut is enlarged and has the capacity for microbial fermentation. Black-crested Sumatran langurs feed from up to 197 different species of trees. It prefers new leaves to mature leaves. ^[4]

Predation

The main predators of black-crested Sumatran langurs include snakes in the genus Python and birds of prey, including crested serpent eagles. ^[5]
