Scientists have identified a new species of monkey, Colobus congoensis, in the Democratic Republic of the Congo’s Lomami National Park. According to Florida Atlantic University, the primate is distinguished by a mask-like face with a vivid orange-cream patch around its mouth and nose. It marks only the fifth new monkey species discovered in Africa in the last 75 years.
The Discovery of Colobus congoensis
Known locally as the “Likweli,” the monkey was formally identified by researchers who noted both its unique physical appearance and distinct vocalizations. The species is characterized by its small, black frame and the aforementioned light-colored skin patterns around the muzzle. Research into the primate’s behavior revealed that its roaring possesses a distinct acoustic structure.

Did you know?
The discovery of the Likweli monkey is a rarity in modern primatology. Only four other monkey species have been identified across the African continent in the last 75 years, highlighting the vast, undocumented biodiversity remaining in the Central Congo Basin.
Conservation Risks and Proposed Status
Despite the excitement surrounding the discovery, researchers are already sounding the alarm regarding the species’ future. John Hart, a conservation scientist from the Lukuru Wildlife Research Foundation, noted that the find underscores how much of the region’s wildlife remains uncatalogued. Because the monkey occupies a limited range and exists in a small total population, experts are urging the International Union for Conservation of Nature (IUCN) to classify Colobus congoensis as endangered.
Why Biodiversity Mapping Matters
The identification of the Likweli serves as a critical case study for conservation efforts in the Congo Basin. When species are identified as having small, localized habitats, they become immediate priorities for protection. Without formal recognition by international bodies like the IUCN, these animals often lack the legal frameworks necessary to prevent habitat loss or poaching.
If you are interested in tracking global conservation efforts, the IUCN Red List of Threatened Species is the authoritative source for the extinction risk status of plants, animals, and fungi.
Frequently Asked Questions
- Where was the Likweli monkey discovered?
The monkey was identified in the Lomami National Park, located in the Democratic Republic of the Congo. - What makes this species unique?
Beyond its distinct orange-cream facial markings, the monkey has a unique acoustic structure to its roar. - Is the species considered endangered?
Researchers have proposed that the IUCN classify it as endangered due to its small population size and restricted geographic range.
