Lesula (Cercopithecus lomamiensis) has a naked face and a mane of long blond hairs, and is described by the researchers who identified it as shy and quiet. It lives on the ground and in trees in a 6,500 square mile habitat of the lowland rainforests in the centre of the DRC between the middle Lomami (the inspiration for its name) and the upper Tshuapa Rivers. Its diet is mostly fruit and vegetation.
