The Indochinese black langur ( Trachypithecus ebenus ) is a species of primate from the group of the slender monkeys (Presbytini). Within the crested langurs it belongs to the francoisi group , a group of predominantly black langurs that live mainly on the Indochinese peninsula .

In contrast to the other representatives of the francoisi group, the Indochinese black langurs have a completely black fur - they lack the white facial markings of the other species. Like all crested langurs, they are slender primates with a mop of hair on the head and a very long tail.

These primates live in Vietnam and Laos . They occur in Laos in the provinces of Khammuan and Savannakhet and in Vietnam in the province of Quảng Bình . The habitat are forested karst regions .

Little is known about the way of life, presumably it corresponds to that of the other crested langurs. As a result, Indochinese black langurs are diurnal tree dwellers who live in harem groups with a male, one or more females and the young and feed mainly on leaves and other plant material. The degree of endangerment of this species is also not known.

The Indochinese black langur was first described in 1995 , initially as a subspecies of the black crested langur . Today, however, it is listed as a member of the francoisi group, either as a separate species or as a subspecies of the Tonkin black langur .
