The Indochinese grey langur (Trachypithecus crepusculus) is a species of Old World monkey native to East and Southeast Asia. It was formerly considered the same species as Phayre's leaf monkey, but a 2009 study found it to be distinct and the most basal member of the Trachypithecus obscurus lineage, and later studies found it to be a hybrid species that arose from ancient hybridization between ancestral obscurus-group langurs and the Tenasserim lutung. It is found throughout Indochina, from northern Thailand east to Vietnam and west to eastern Myanmar, and north into southern China south of the Salween River. Unlike the langurs that live in karst forests and are largely terrestrial, it lives in old-growth evergreen forests and has a largely arboreal lifestyle. The population is thought to be only about 2,400 to 2,500 mature individuals. Habitat destruction threatens it and, especially in Vietnam and Laos, so does hunting, which is thought to have caused rapid declines.
