New monkey species with orange lips found 'hiding' in DRC forest

The black-furred primate was spotted and photographed hidden away in the high tree canopy of dense tropical forests in Lomami National Park, in the central east of the country. Conservationists working there first reported seeing this unusual-looking animal back in 2008. But they captured just one blurry photograph. After another sighting 10 years later, an international team set out to find and study the monkey and revealed that it was a previously unknown species. This is only the fifth African monkey species to be discovered in the last 75 years. Junior Amboko, a PhD student at Florida Atlantic University, played a leading role in the search, which involved audio recordings, photography and detailed genetic studies. The findings were published in the journal PLoS One , external . Amboko told BBC News it was an "amazing feeling" to look into the face of an animal that so few people knew existed.

Koko recorded the distinctive, resonant roar of the newly discovered Colobus congoensis monkey in the Lomami National Park, DRC "Discovering" a species, in this context, means officially recording and confirming it has evolved to be genetically distinct. Some local people already knew of the monkey's existence and refer to it by a common name - Likweli. But Amboko said the monkeys were "kind of shy" - and tended to hide high in the trees. "As part of our search, we interviewed people in 52 villages close to where the animals live. And only people in eight villages [had ever seen] them," he recalled. The research team - from DRC, the US and Germany - gave the animal the Latin name Colobus congoensis in recognition of the natural diversity in the country. It belongs to the larger group of colobus monkeys. "These are really important African monkeys that don't have thumbs," explained Prof Kate Detwiler from Florida Atlantic University.

We think they have a lot to do with processing seeds and germination in the forest." Prof Detwiler speculates that their unusual, bright facial markings could be a visual signal to other animals, potentially attractive to a mate or that it could allow the animals to identify each other. The monkeys also have a distinctive "roaring" call. "You often hear them, but don't see them," said Amboko. They think the animals are rare and restricted to a
