Laos Langur Distribution

Laotian Langur Characteristics

The Laotian langur[1] (Trachypithecus laotum), also known as white-browed black langur, is another primate species in the Cercopithecidae family.

  • Its natural habitat is tropical or subtropical dry forests. These graceful langurs are long, slender, and muscular, with shiny black fur that covers the entire body and tail.
  • The stripe of white fur that grows on their cheeks resembles a delicate touch of color and gives them a distinguished look.
  • It extends above and behind their rounded ears to the nape of their neck. Their smooth oval face is crowned by a bristly lock of hair.
  • Their eyes are brown, and their nostrils are slanted downwards.
  • They also have 5 digits on their feet and hands, making them very dexterous.

Laotian Langur Facts

  • Laotian langurs nest in small limestone caves and holes that shelter from predators, rain, and cold.
  • Unlike other species, they have used the same roost sites for many years.
  • They live in groups of 5-30 individuals, with an average group size of 15 depending on the quality of their environment.
  • Adult male species make loud noises upon waking, and the dominant male is likely to be the first to go when the group leaves the sleeping area at dawn to feed for a few hours.
  • Laotian langurs communicate with touch and body posture; for example, adult females often cuddle.
