The lesula lives in rainforests in the Democratic Republic of Congo, with the 2007 specimen found in captivity in the village of Opala. Since that sighting, it has also been seen in the wild. Its range is between the Lomami and Tshuapa rivers in the central part of the country.7
The lesula is vulnerable to hunting for bushmeat.8 Protecting the species could be challenging, as species with such a small range can go from vulnerable to seriously endangered in a few years. The lesula's range is within the Tshuapa–Lomami–Lualaba Conservation Landscape, and the Lomami National Park has been proposed to protect this and other species in the region.
The lesula are generally described by researchers as quiet and shy.9 They also tend to usually live in small family groups of around five members or less. The Lesula's days consist of leisurely activities such as foraging for fruits and vegetation, grooming, and resting.
