Cercocebus É. Geoffroy, 1812

Cercopithecine genus to which the mangabeys belong. There are four species with an estimated five subspecies. Distributed in varied types of forest of western and central equatorial Africa. Arboreal; diurnal; quadrupedal. Body mass from 3 to 12 kg; sexual dimorphism in body size. Dental formula: 2.1.2.3; frugivorous. Possess cheek pouches for storing food. Lives in bands of 10-20 individuals, including both mixed-sex groups and one-male units. Recent taxonomic revision based on morphology, biochemistry, and ecology resulted in the black mangabeys being moved to the genus Lophocebus. Evidence suggests that Cercocebus shares ancestry with Mandrillus whereas Lophocebus is more closely related to Papio and Theropithecus.
