A new monkey species with pinkish-orange lips and a black face has been confirmed in the Democratic Republic of Congo, marking the fifth African monkey discovery in 75 years. The species, named Colobus congoensis, was identified through fieldwork in Lomami National Park, with researchers highlighting its ecological importance and vulnerability to hunting.
The discovery of the newly named Colobus congoensis, a black-furred primate with striking facial features, represents a significant milestone in African wildlife research. First documented in 2008 by conservationists in Lomami National Park, the species remained elusive until an international team led by Junior Amboko, a PhD student at Florida Atlantic University, conducted extensive fieldwork involving audio recordings, photography, and genetic analysis. The findings, published in the journal PLoS One, confirm the monkey as a genetically distinct species, with local communities having long referred to it as “Likweli.”
Elusive Discovery: From Blurry Photos to Scientific Confirmation
The journey to formally recognize Colobus congoensis began a decade after conservationists first spotted the primate in 2008. Initial attempts to study the species were hampered by its secretive nature—Amboko noted that the monkeys tend to hide high in the trees and are “kind of shy.” A breakthrough came when researchers returned to the region, conducting interviews in 52 villages near the park. Only eight communities reported sightings, underscoring the animal’s rarity and the challenges of studying such an elusive creature.
The team’s work involved capturing audio of the monkeys’ “distinctive roaring call,” which Amboko described as something you often hear but don’t see. Genetic studies and physical observations ultimately confirmed the species’ uniqueness. The research, supported by scientists from the DRC, the U.S., and Germany, culminated in the official naming of Colobus congoensis—a nod to the country’s biodiversity. It’s an amazing feeling to look into the face of an animal that so few people knew existed, Amboko told BBC News.

Ecological Role and Conservation Concerns
Colobus congoensis belongs to the colobus monkey family, known for their leaf-eating habits and critical role in seed dispersal within tropical forests. Prof. Kate Detwiler of Florida Atlantic University emphasized their ecological significance, noting that these primates process seeds and germination in the forest. However, the species faces threats from hunting for bushmeat, prompting researchers to advocate for its protection now that it has been officially classified.
The monkeys’ bright facial markings, which Detwiler speculates could serve as “a visual signal to other animals” or aid in mate recognition, add to the intrigue surrounding the species. Yet much remains unknown. Amboko highlighted the need for further research: “We still have many questions about this newly described, secretive species.” The team plans to conduct more detailed surveys to estimate population numbers and study behavior, but challenges persist due to the animal’s reclusive nature.
What’s Next for Colobus Congoensis?
The classification of Colobus congoensis as a distinct species is a critical step toward conservation efforts, but its future remains uncertain. Researchers stress the need for targeted protection measures, particularly in Lomami National Park, where the monkeys are believed to be restricted to specific habitats. The lack of comprehensive data on their population size and distribution complicates these efforts, as does the ongoing threat of poaching.
For now, the discovery underscores the importance of continued exploration in the DRC’s biodiverse regions. As Amboko noted, “You often hear them, but don’t see them”—a reminder of how much remains hidden in the world’s forests. The next phase of research will determine whether Colobus congoensis can be safeguarded against the pressures threatening its survival.
