Delacour’s Langur
Trachypithecus delacouri (Osgood, 1932)
CR A2cd+3cd; C2a(i)

Delacour’s langur is one of the most endangered of a group of largely black Southeast Asian leaf-eating monkeys. It is distinguished from the others by its white cheek bands, the large white saddle on its outer thighs and lower back, and its thickly-furred tail. The species, which is endemic to Vietnam, was first described in 1932. Based on recent surveys, the best estimates are that less than 200 Delacour’s langurs survive, including a population in Cuc Phuong National Park, the first national park created by the government of Vietnam in 1962. Like most of Vietnam’s primates, this species is threatened not only by habitat loss, but also by hunting, which is often done not primarily for meat, but for bones, organs and tissues that are used in the preparation of traditional medicines. The Endangered Primate Rescue Center at Cuc Phuong National Park was established earlier this decade primarily to safeguard the future of this species and other Vietnamese primates.
