In 2008, wildlife researchers surveying a massive, underexplored forested region in the Democratic Republic of Congo photographed a black monkey. That region eventually became Lomami National Park. And now, nearly 20 years later, the team has confirmed in a study that the black primate is a new-to-science species of colobus monkey.
The monkey isn’t well known by local communities, but those who have encountered it call it likweli, said John Hart, study lead author and scientific director at the Lukuru Wildlife Research Foundation, which spearheaded the creation of Lomami. The researchers have given the monkey the scientific name Colobus congoensis.
Both male and female likweli are almost entirely black. What makes the species easy to distinguish from other colobus monkeys is a prominent patch of pinkish to orange-cream bare skin surrounding the mouth, Hart told Mongabay in a video call.
When the likweli was first photographed in 2008, it was one of several monkeys the researchers couldn’t identify. “They are not in our field guides,” Terese Hart, the Lukuru foundation director, wrote in a blog post in 2008.
Another of those monkeys, locally named lesula, also turned out to be new to science and was scientifically described as Cercopithecus lomamiensis in 2012.
