  • It belongs to the larger group of colobus monkeys.
  • Scientific name: Its scientific name is Colobus congoensis.
    • It is locally known  as the ‘Likweli’.
  • It was first discovered in 2008.
  • Habitat: It is largely confined to high, closed-canopy upland forests growing on deep clay soils.
  • Distribution:  It lives in the forests of the Democratic Republic of Congo (DRC). 
    • It was identified in the remote interfluve (between rivers) region between the Lomami and Congo (Lualaba) rivers in the DRC in 2008.
  • Characteristics:
    • It is smaller in size than Black bearded saki and most other species of the Colobus genus.
    • It has a black face with a distinctive orange-cream patch around the mouth, the philtrum (the groove between the nose and upper lip), and the lower sides of the nostrils.
    • It has a white patch around the anal region, which is an important identifying feature.
    • In males, the white perianal patch is covered with fine white hairs. In females, the white perianal patch is hairless (glabrous).
    • It does not have thumbs.
    • Diet: It primarily feeds on leaves, shoots, and seedlings
    • Behaviour: It is quiet and cryptic.
      • It is often seen moving in mixed-species groups with up to six different types of primates.
      • It is also known for their rapid, pulse-like roaring calls, which can be distinguished from other species by a distinctive snort produced between roar sequences.
  • Threat: It faces rising threats from hunting pressure and habitat conversion as human populations in the DRC grow.
  • Conservation status: Scientists propose listing it as Endangered on the IUCN Red List.
