The Roloway monkey (Cercopithecus roloway) is an arboreal guenon that inhabits evergreen forests of Côte d'Ivoire and Ghana. Body length ranges from 45 to 60 cm, and weight is about 4–7 kg, with males larger; the tail exceeds body length, reaching 70–90 cm. Its diet is omnivorous, including insects, leaves, fruits, and seeds, and it can store food in cheek pouches. It lives in single-male, multi-female groups of 6–22 individuals, and grooming maintains social relationships. Habitat is being rapidly lost due to illegal logging and hunting; population is estimated at fewer than 2,000 individuals and the species is classified as Critically Endangered (IUCN Category I A).
