"Preuss's monkey (Cercopithecus preussi), also known as Preuss's guenon, is a diurnal primate that lives terrestrially in mountainous (up to 2500 m) forests of eastern Nigeria, western Cameroon and Bioko in Equatorial Guinea. It is sometimes classified as a subspecies of the L'Hoest's monkey (C. lhoesti). The diet of Preuss's monkey is primarily fruit, leaves and insects, although the species occasionally raids human crops."@en . . "Preuss's monkey"@en . "iucn3.1" . .
