Scientists Describe New Colobus Monkey, Likweli, From the Congo

Published July 15 in PLOS One, the formal description names Colobus congoensis and urges protection because its tiny range and hunting pressure put it at risk.

Overview

  • Researchers published a formal description of Colobus congoensis, called Likweli, on July 15 after analyzing genetics, skull and skin comparisons, and recorded vocalizations.
  • Field teams recorded 114 observations between 2018 and 2022 across roughly 1,700 square kilometers in and around Lomami National Park, establishing a narrow, upland forest range.
  • Genetic dating shows Likweli split from its closest known relative about 4 to 5 million years ago, making it a deep and distinct lineage within Colobus monkeys.
  • The team reports ongoing hunting and habitat loss in the species’ limited range, recommends IUCN assessment as Endangered, and has deposited three confiscated specimens at the Yale Peabody Museum.
  • The find is rare for modern primatology and highlights Lomami’s high endemism, the value of long‑term local fieldwork, and the need for park protection and community engagement to keep the species viable.
