New Primate Species Discovered in the Congo Basin

Known locally as the Likweli, the monkey is distinguished by its glossy black fur, a vibrant orange facial patch, and large folded ears. Weighing approximately 15 pounds, the species occupies an unusually restricted range of 1,700 square kilometers between the Lomami and Congo rivers. Genetic analysis reveals a surprising evolutionary history: despite living 1,200 kilometers from its closest relative, Colobus satanas, the two species diverged from a common ancestor four to five million years ago.

An international team, including researchers from Florida Atlantic University and the Lukuru Wildlife Research Foundation, spent a decade confirming the species through skeletal comparisons and acoustic recordings. Junior Amboko, a PhD student and National Geographic Explorer, noted the find underscores the immense biodiversity of the region. However, the discovery comes with an urgent conservation warning. With only 114 sightings recorded between 2018 and 2022, experts are recommending an Endangered status on the IUCN Red List. Habitat loss and hunting pressure threaten the population, making the protection of Lomami National Park vital to preventing the loss of the species before it is fully understood.
