The white-eyelid mangabeys are African Old World monkeys belonging to the genus Cercocebus. They are characterized by their bare upper eyelids, which are lighter than their facial skin colouring, and the uniformly coloured hairs of the fur.The other two genera of mangabeys, Lophocebus and Rungwecebus , were once thought to be very closely related to Cercocebus, so much so that all the species were placed in one genus. However, it is now understood that Lophocebus and Rungwecebus species are more closely related to the baboons in genus Papio, while the Cercocebus species are more closely related to the mandrill.
Old World monkey is the common English name for a family of primates known taxonomically as the Cercopithecidae. Twenty-four genera and 138 species are recognized, making it the largest primate family. Old World monkey genera include baboons, macaques, and mabahlls. Common names for other Old World monkeys include the talapoin, guenon, colobus, douc, vervet, gelada, mangabey, langur, mandrill, surili (Presbytis), patas, and proboscis monkey. Phylogenetically, they are more closely related to apes than to New World monkeys. They diverged from a common ancestor of New World monkeys around 55 million years ago.
The Cercopithecinae are a subfamily of the Old World monkeys, which comprises roughly 71 species, including the baboons, the macaques, and the vervet monkeys. Most cercopithecine monkeys are limited to sub-Saharan Africa, although the macaques range from the far eastern parts of Asia through northern Africa, as well as on Gibraltar.
The golden-bellied mangabey is a social Old World monkey found in swampy, humid forests south of the Congo River in the Democratic Republic of the Congo. It was previously considered a subspecies of the agile mangabey . Little is published about the species and its behaviour has only been studied in captivity.
The grey-cheeked mangabey, also known as the white-cheeked mangabey, is an Old World monkey found in the forests of Central Africa. It ranges from Cameroon down to Gabon. The grey-cheeked mangabey is a dark monkey, looking in shape overall like a small, hairy baboon. Its thick brown fur is almost black in its forest home, with a slightly rufus/golden mane around the neck. The sexes are similar, with the males slightly larger than the females.
The term mangabey can refer to three different genera of Old World monkeys in the tribe Papionini.
The kipunji, also known as the highland mangabey, is a species of Old World monkey that lives in the highland forests of Tanzania. The kipunji has a unique call, described as a 'honk-bark', which distinguishes it from its relatives, the grey-cheeked mangabey and the black crested mangabey, whose calls are described as 'whoop-gobbles'.
The sooty mangabey is an Old World monkey found in forests from Senegal in a margin along the coast down to the Ivory Coast.
The crested mangabeys are West African Old World monkeys belonging to the genus Lophocebus. They tend to have dark skin, eyelids that match their facial skin, and crests of hair on their heads. Another genus of mangabeys, Cercocebus, was once thought to be very closely related, so much so that all the species were placed in one genus. However, Lophocebus species are now understood to be more closely related to the baboons in genus Papio, while the Cercocebus species are more closely related to the mandrill. In 2006, the highland mangabey was moved from Lophocebus to a new genus, Rungwecebus.
The Papionini are a tribe of Old World monkeys that includes several large monkey species, which include the macaques of North Africa and Asia, as well as the baboons, geladas, mangabeys, kipunji, drills, and mandrills, which are essentially from sub-Saharan Africa. It is typically divided into two subtribes: Macacina for the genus Macaca and its extinct relatives and the Papionina for all other genera.
The Tana River mangabey is a highly endangered species of primate in the family Cercopithecidae. Some authorities have included the taxa agilis and sanjei as subspecies of this species, while others award these full species status.
The collared mangabey, also known as the red-capped mangabey, or the white-collared mangabey, is a species of primate in the family Cercopithecidae of Old World monkeys. It formerly included the sooty mangabey as a subspecies. As presently defined, the collared mangabey is monotypic.
The black crested mangabey is a species of primate in the family Cercopithecidae. It is found in Angola and Democratic Republic of the Congo. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.
The agile mangabey is an Old World monkey of the white-eyelid mangabey group found in swampy forests of Central Africa in Equatorial Guinea, Cameroon, Gabon, Central African Republic, Republic of Congo, and DR Congo. Until 1978, it was considered a subspecies of the Tana River mangabey. More recently, the golden-bellied mangabey has been considered a separate species instead of a subspecies of the agile mangabey.
The Sanje mangabey is a highly endangered Old World monkey of the white-eyelid mangabey group from the Eastern Arc Mountains in Tanzania. They are about 50–65 centimetres (20–26 in) in length, excluding the tail, and their body colour is greyish. Fruit makes up about 70% of their diet. They live in valley forests and on mountain slopes, but are mostly ground-dwelling, which makes them susceptible to hunting and poaching. Their habitat is being degraded, and the International Union for Conservation of Nature has assessed their conservation status as being "endangered".
Opdenbosch's mangabey is a species of crested mangabey in the family Cercopithecidae. It has also been treated as a subspecies of Lophocebus aterrimus. It is found in the Democratic Republic of the Congo.
Johnston's mangabey is a species of crested mangabey in the family Cercopithecidae. It had been considered a subspecies of the gray-cheeked mangabey, but in 2007 was given the status of species by Colin Groves, with Osman Hill's mangabey and the Uganda mangabey.
The Osman Hill's mangabey, also known as the rusty-mantled mangabey, is a species of crested mangabey in the family Cercopithecidae with a restricted distribution in West Africa.
