New monkey species with orange lips discovered in Congo rainforest

After an 18-year search, researchers have formally identified a new species of monkey in the Democratic Republic of Congo, distinguished by its orange-cream facial markings and deep, roaring call. Known locally as Likweli, the primate has been scientifically named Colobus congoensis and is only the fifth new monkey species described in Africa in the past 75 years Source: CNN.

Key findings

The monkey was first glimpsed in 2008 as a blurry photo, but clearer sightings in 2018 prompted a comprehensive study. Between 2018 and 2022, researchers documented 114 sightings across roughly 1,700 square kilometres of forest Source: euronews. Genetic analysis shows C. congoensis diverged from its closest relative, the black colobus (Colobus satanas), about 4–5 million years ago Source: Gizmodo.

• Call: A distinctive froglike roar with a unique acoustic structure Source: BBC.
• Local knowledge: Only eight of 52 villages surveyed recognised the species, indicating its rarity Source: euronews.

Conservation concerns

Researchers propose that Colobus congoensis be classified as Endangered due to its restricted range, habitat loss, and hunting pressure Source: CNN. Most of its known habitat lies within Lomami National Park, making park protection critical for its survival Source: CNA.
