New “Likweli” Monkey Species Confirmed in Congo’s Lomami Forest

Discovery and Formal Description
Scientists have officially recognized a previously unknown colobus monkey as a distinct species, Colobus congoensis, after publishing a peer-reviewed paper in *PLOS One* on 15 July 2026. The primate, locally called “Likweli,” was documented in the dense canopy of Lomami National Park in the central-east of the Democratic Republic of Congo (DRC). The description follows extensive fieldwork, genetic sequencing, anatomical comparison, and acoustic analysis that together demonstrated its evolutionary separation from all known colobus taxa.
Background & Context
The first hint of the animal appeared in 2008 when conservationists captured a single blurry photograph during an expedition along the Lomami River. A clearer sighting in 2018 prompted a focused “Likweli Project,” leading to systematic surveys between 2018 and 2022. This discovery marks only the fifth new African monkey species described in the past 75 years, the previous one being the Lesula in 2012.
Key Researchers and Institutions
The multinational team included Junior Amboko (PhD student, Florida Atlantic University), Prof. Kate Detwiler (FAU), Julia Arenson (postdoctoral fellow, Yale University), John A. Hart (Lukuru Wildlife Research Foundation), Christopher Gilbert (City University of New York), and collaborators from the Congolese Institute for Nature Conservation (ICCN), Frankfurt Zoological Society, and Hunter College.
Physical Characteristics and Genetic Distinction
*Colobus congoensis* is a medium-sized colobus (? 7 kg) with glossy black fur, a striking orange-cream facial mask, bare grey cheekbones, and a white perianal patch. Like all colobus monkeys, it lacks a thumb. Acoustic recordings reveal deep, resonant roars distinct from related species. Mitochondrial DNA shows a divergence of 4–5 million years from its closest relative, the black colobus (*Colobus satanas*), a split longer than any other within the genus.
Data & Statistics
- Estimated range: ? 1,700 km² between the Lomami and Lualaba rivers.
- 114 sightings recorded from 2018-2022.
- Surveys of 52 nearby villages found only 8 villages where residents had ever seen the monkey.
- Genetic analyses confirm a unique lineage separate from all other African colobines.
Conservation Implications
Researchers note that the species is hunted for bushmeat and faces ongoing habitat conversion. Because most of its habitat lies inside Lomami National Park, the team recommends listing *C. congoensis* as Endangered on the IUCN Red List and strengthening anti-poaching patrols. The discovery underscores the park’s role as a refuge for endemic wildlife.
Official Statements & Responses
Team members emphasize both scientific excitement and urgency. Amboko described the moment of seeing the animal as “an amazing feeling.” Detwiler called the finding “both a scientific triumph and a sobering reminder that some of Earth’s rarest creatures may vanish before the world even knows they exist.” Hart highlighted the indispensable contribution of Congolese field naturalists, while Arenson stressed that multiple independent datasets converged on the same taxonomic conclusion.
Criticism & Opposition
Conservationists warn that formal recognition alone will not halt hunting pressure. Without rapid implementation of protective measures, the limited-range population could decline sharply, a concern echoed by local NGOs monitoring bushmeat trade.

- “Amboko told BBC News it was an "amazing feeling" to look into the face of an animal that so few people knew existed.” — Junior Amboko, PhD student, Florida Atlantic University
- “Our team evaluated multiple datasets that all reached the same conclusion: Likweli is a distinct species of Colobus monkey we haven’t seen before,” — Julia Arenson, postdoctoral fellow, Yale University
- “The discovery of Colobus congoensis is both a scientific triumph and a sobering reminder that some of Earth’s rarest creatures may vanish before the world even knows they exist,” — Kate Detwiler, senior author, Florida Atlantic University
- “The discovery and documentation of the Likweli never would have happened without our team of Congolese explorer naturalists,” — John Hart, lead author, Lukuru Wildlife Research Foundation
- “Discovering a primate species is exceptionally rare, especially from populations previously unknown to science.” — Julia Arenson, Yale University
What’s Next
The team plans a detailed population survey to estimate numbers, map precise distribution, and study feeding and social behavior. Findings will inform a formal IUCN assessment and guide targeted conservation actions within Lomami National Park.
