The discovery of Colobus congoensis, locally known as 'Likweli', marks a significant breakthrough in modern primatology as it is only the fifth new monkey species identified in Africa over the past 75 years. Research led by an international team confirmed the species through genetic, anatomical, and acoustic analyses, revealing it diverged from its closest relatives 4 to 5 million years ago. Found in the rainforests of the DRC, the monkey is characterized by its glossy black coat and unique orange facial markings. Due to its restricted habitat and threats from hunting, experts have proposed its inclusion on the IUCN Red List.
