The Hatinh Langur ( Trachypithecus hatinhensis ) is a species of primate from the group of the Schlankaffen (Presbytini). It lives on the Indochinese Peninsula and is sometimes listed as a subspecies of the Tonkin black langur or the southern black langur .

features

Hatinh langurs are similar to the closely related Tonkin black langurs. As with these, their fur is predominantly black in color and a white stripe runs from the corners of their mouths to their ears. In this species, however, the white fur pattern extends further back to the neck. At the top of the head is a head of hair typical of many crested langurs . The tail is longer than the body, the hands and feet are narrow, and the thumb is very small. These primates reach a head body length of 50 to 67 centimeters, the tail is 81 to 87 centimeters long.

Distribution and way of life

Yellow, the habitat of the Hatinh langur

Hatinh langurs occur in the central part of Vietnam , they live in the provinces of Quảng Bình and Quảng Trị . Presumably there is also a population in the adjacent part of Laos . The habitat of these animals are forested limestone areas .

Little is known about the way of life, presumably it largely corresponds to that of the Tonkin black langur. Hatinh langurs are diurnal and mostly stay in the trees, when they sleep they retreat in caves or on cliffs. They live in groups of 5 to 15 animals, which are made up of a male, one or more females and their young animals. They are herbivores, with leaves making up most of the diet. Like all slender monkeys, they have a multi-chambered stomach for a better breakdown of the difficult to digest food.

Hatinh langurs and humans

The Hatinh langur was scientifically described in 1970 , but was then lost until 1992. The main threat is hunting and habitat loss through forest clearing. Today, the largest populations are in the Phong-Nha-Ke-Bang National Park in central Vietnam, the IUCN lists the Hatinh langurs as endangered .
