genus ''Cercopithecus'', found in the
Lomami Basin of the
Congo. Though known to locals, it was unknown to the international scientific community until it was discovered in 2007 and confirmed in a 2012 publication. The lesula is the second new species of African monkey to be discovered since 1984. This monkey is described to have human looking eyes and a blue bottom
“And adult males have a huge bare patch of skin in the buttocks, testicles and perianal area,” said John A. Hart, the researcher who described the monkey. “It’s a brilliant blue, really pretty spectacular.”
The species was listed among the ''Top 10 New Species 2013'' discovered in 2012 as selected by the
International Institute for Species Exploration
The International Institute for Species Exploration (IISE) was a research institute located in Syracuse, New York. Its mission was to improve Taxonomy (biology), taxonomical exploration and the cataloging of new species of flora and fauna. Betw ...

. 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.
Behavior
The lesula are generally described by researchers as quiet and shy.
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.
