Annamese Silvered Langur Characteristics

Annamese Silvered Langur

The Annamese langur is another Old-World monkey in the subfamily Colobinae.

  • Annamese langurs[1] are covered in thick, gray fur. They have dark faces, and the space around the eyes is pale and forms a ring, often in the flesh.
  • The hair of the head forms a hood or cap. The abdomen is a lighter gray than the rest of the torso, as are the legs and the underside of the tail.
  • They have black hands and feet. Infant Annamese langurs are very easy to identify as they have a surprisingly glossy golden-orange coat that contrasts starkly with the gray color of the adults.
  • After a few months, this orange coat begins to turn grayish until the juveniles are the same coloring as the adults.

Annamese Silvered Langur Facts

  • A distinctive feature of all langurs of the Trachypithecus group is the orange pelage of their young.
  • Trachypithecus margarita is a monotypic species as it has no subspecies.
  • Previously, it was considered a subspecies of Trachypithecus germaini until it was elevated to a species of its own by Roos and Groves[2].
  • Its fur is lighter than the Indochinese silvery langur (Trachypithecus germaini).
  • The diet of these langurs is similar to that of other Trachypithecus species, characterized by a large consumption of leaves and supplemented with fruits.
