What Happened
Where Sources Agree
- arrows_inputOfficial Species Identification: Sources verify the official identification of Colobus congoensis—a new monkey species known locally as Likweli—which marks the fifth such discovery in Africa over the last 75 years, according to a PLOS One study.
- arrows_inputNew Monkey Species Discovered: Coverage confirms researchers have identified a new monkey species, Colobus congoensis, in the Democratic Republic of the Congo; the primate is distinguished by an orange-cream mouth patch and evolutionary divergence four to five million years ago, according to scientific analysis published in PLOS One.
- arrows_inputEndangered Conservation Status Proposed: Coverage documents that researchers propose listing the new monkey species Colobus congoensis as Endangered, citing its limited 1,700 square kilometer range, habitat loss, and hunting pressure, according to the IUCN Red List proposal.
Where Sources Disagree
- arrows_outputReported Species Weight: Reports vary slightly on the monkey's weight, with some sources citing 7 kilograms and others noting 6.8 kilograms.
- arrows_outputLocal Species Naming: Some outlets identify the newly discovered monkey species solely by the local name 'Likweli,' while others report that regional communities use both 'Likweli' and 'Kasaba Nkoni.'
- arrows_outputHistorical Sighting Timeline: Most sources report the species was first identified through a photographic sighting in 2008. However, one source asserts the last conclusive sighting occurred in 1978, creating a significant discrepancy in the species' documented history.
Timeline
January 1, 2026
Conservation concerns and proposals: Researchers report C. congoensis has a very limited range and small population, faces hunting and habitat-loss pressures, and may qualify as Endangered; they have proposed listing it on the IUCN Red List and called for protection of Lomami National Park and engagement with local communities. The species' confined 1,700 km² relict range and threats underlie urgent conservation action.
January 1, 2026
Analyses confirm new species: Genetic, anatomical and acoustic analyses—reported in a 2026 PLOS One paper—confirmed the primate is a previously undescribed species named Colobus congoensis (Likweli), found in Lomami National Park and deeply divergent (about 4–5 million years) from its nearest relative, Colobus satanas. The international team published the formal description and naming in PLOS One.
December 31, 2022
Systematic field surveys 2018–2022: Between 2018 and 2022 researchers recorded 114 field observations across an estimated range of roughly 1,700 square kilometres, interviewed people in 52 villages (only eight reported sightings), and launched the Likweli Project in 2020 to classify the mysterious monkey. Field teams collected photos, calls and specimen data to build the evidence base.
