The Natuna langur ( Presbytis natunae ) is a species of primate from the group of the slim monkeys (Presbytini).

Like all cap langurs, Natuna langurs are relatively small, slender primates with long hind legs and a long tail. Their fur is gray-brown on the back, the belly is lighter. The face is dark in color, the light circles under the eyes and the light muzzle region are conspicuous, and there is a mop of hair on the top of the head.

Distribution area of ​​the Natuna langur

Natuna langurs live exclusively on the Natuna Islands, which are located between Borneo and the Malay Peninsula and belong to Indonesia ( Kepulauan Riau Province ) . Their habitat are forests, although they live almost exclusively in primary forests .

Little is known about their way of life, presumably it corresponds to that of the other cap langurs. They live in small groups of two to six animals, usually a male, one or more females and their young animals. They are tree dwellers who can climb very skillfully and, like all old world monkeys, are diurnal. Their diet should consist of plants, mainly young leaves, seeds and fruits.

Systematically, the species has only been considered an independent species since 2001, earlier it was assigned to the bandage or white-legged langur .

Natuna langurs are among the most threatened primate species. The reasons for this are, on the one hand, the small size of their distribution area (around 1,600 km²), but the main reason is that most of the forests on their home island have been cleared since the 1980s. In addition, the residents of the Natuna Islands like to keep these primates as pets. A study by Martjan Lammertink et al. from 2003 estimates the total population at less than 10,000 animals and calls for the establishment of two protected areas to ensure the continued existence of the species.
