Lophocebus albigena

SUBFAMILY

Cercopithecinae

TRIBE

Papionini

TAXONOMY

Lophocebus albigena (Gray, 1850), Mayombe, Zaire. Traditionally, all mangabeys were included in the genus Cercocebus. However, morphological evidence that was subsequently confirmed by molecular data indicated that there are, in fact, two distinct groups that have independently undergone shortening

of the face, such that a pronounced hollow (fossa) has developed below each eye socket. Predominantly arboreal mangabeys that are more closely allied to baboons are now allocated to the separate genus Lophocebus.

Head and body length: 22.5 in (56.0 cm) for males and 21 in (52.0 cm) for females; tail length: 32 in (80.0 cm) for males and 28.5 in (71.5 cm) for females.
