- A new Colobus monkey species named Colobus congoensis, called Likweli, was discovered in the Democratic Republic of Congo.
- The species is cryptic, small, black, with orange-cream facial patches, and lives high in forest canopies of Lomami National Park.
- Evidence from physical traits, genetics, and vocalizations confirms Likweli as distinct from other Colobus species.
- Only 114 observations were recorded from 2018-2022 over about 1,700 km², with groups of about six individuals.
- Likweli's range is limited, and it is rare, with few local villagers aware of it, suggesting a cryptic nature.
- Genetic analysis indicates Likweli split from its sister species Colobus satanas about 4.7-5.8 million years ago.
- The discovery highlights the biodiversity of Lomami National Park and the need for conservation efforts.
- Researchers recommend classifying Likweli as endangered due to its small population, hunting, and habitat encroachment.
