Researchers Confirm New Colobus Monkey Species in Democratic Republic of Congo

Genetic, anatomical and acoustic evidence showed the monkey is a distinct lineage, and researchers say its limited range could justify endangered status.

  • On Wednesday, researchers published confirmation in PLOS One that Colobus congoensis, known locally as Likweli, is a new monkey species identified through genetic, anatomical and acoustic analyses—only the fifth such African primate discovery in 75 years.
  • The discovery began in 2008 when Lukuru Wildlife Research Foundation conservationists Bernard Ikembelo and Ashley Vosper captured a blurry photograph; a decade later, surveillance patrol leader Jean Pierre Kapale obtained a much clearer image in November 2018, sparking seven additional documented sightings over 10 months.
  • Likwelis weigh about 7 kilograms with glossy black fur and striking orange-cream facial markings, while genetic analysis reveals they diverged from their closest relative, Colobus satanas, roughly 4 to 5 million years ago; researchers recorded 114 sightings across 1,700 square kilometers between 2018 and 2022.
  • Researchers propose classifying the species as Endangered on the IUCN Red List due to its restricted range and small population; study senior author Kate Detwiler, an associate professor of biological sciences at Florida Atlantic University, cited hunting pressure and habitat loss as primary threats.
  • The Congo Basin remains a frontier for mammal discovery; researchers interviewed residents in 52 villages but only 8 recognized the species, explaining why it remained undocumented for decades, and study authors now plan research into Likweli's diet, behavior and reproduction.
