Description Edit

The doucs are colobine Old World monkeys, which make up the genus Pygathrix. They are native to Southeast Asia.

Classification Edit

The doucs make up the genus Pygathrix, which consists of these 3 species:

Genus PygathrixLinnaeus, 1771 – three species
Common name Scientific name and subspecies Range Size and ecology IUCN status and estimated population
Red-shanked douc


Pygathrix nemaeus
(Linnaeus, 1771)
Indochina; Vietnam, southern Laos and possibly northeastern Cambodia



Black-shanked douc


Pygathrix nigripes
Milne-Edwards, 1871
Cambodia and Vietnam



Gray-shanked douc


Pygathrix cinerea
(Nadler, 1997)



Even though they are known as "douc langurs", they are in fact more closely related to the proboscis monkey and snub-nosed monkeys than to any of the langurs. They are part of the subfamily Colobinae of the family Cercopithecidae.

Appearance Edit

Doucs have a distinct appearance. The red-shanked douc characteristically has bright maroon legs and reddish patches around the eyes. In contrast, the grey-shanked douc is less vibrant, with speckled grey legs and orange markings on the face. Both have dappled grey bodies, black hands and feet and white cheeks, although the cheek hairs of the red-shanked douc are much longer. The black-shanked douc has black legs. Their long hind limbs and tail allow these monkeys to be very agile in their treetop habitat.

Behavior Edit

They live in small family groups headed by one adult male. A single group may have several adult females, and many children. Young males unaffiliated with a family group often make their own troops. Females usually bear a single offspring at a time, which is suckled for about a year.[2]
