New Primate Species Discovered in Congo Faces Immediate Extinction Risk

A new species of monkey, named Colobus congoensis and locally called Likweli, has been identified in the forests of the Democratic Republic of Congo. Initially photographed in 2008 near the Lomami River, the species was only confirmed as new to science nearly two decades later after further sightings and genetic analysis. The monkey is distinctive for its shiny black fur and an orange patch around its mouth and nose.

Between 2018 and 2022, researchers documented 114 encounters with Likweli within a 1,700 square kilometer area. These monkeys live high in the treetops in small groups averaging six individuals and weigh about 6.8 kilograms, smaller than related colobus species. Despite extensive surveys in 52 nearby villages, only residents of eight recognized the species, underscoring its rarity.

A breakthrough came in 2021 when park rangers confiscated three dead Likweli monkeys from hunters, enabling scientists to conduct comprehensive genetic, anatomical, and vocalization studies. These confirmed Likweli as a distinct species. However, researchers warn the species may already be endangered due to habitat loss, hunting, and expanding human settlements around Lomami National Park.

Scientists recommend classifying Likweli as endangered, though this status has not yet been officially recognized by the International Union for Conservation of Nature. The discovery marks the fifth new primate species found in Africa in the last 75 years, highlighting both the region's biodiversity and the urgent need for conservation efforts.
