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 and macaques. 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 45 to 55 million years ago.
The guenons are the genus Cercopithecus of Old World monkeys. Not all members of this genus have the word "guenon" in their common names; also, because of changes in scientific classification, some monkeys in other genera may have common names that include the word "guenon". Nonetheless, the use of the term guenon for monkeys of this genus is widely accepted.
Sclater's guenon, also known as Sclater's monkey and the Nigerian monkey, is an Old World monkey that was first described by Reginald Innes Pocock in 1904 and named after Philip Sclater. It is an arboreal and diurnal primate that lives in the forests of southern Nigeria. It should not be confused with the closely related species, the white-throated guenon, which occurs in Nigeria and Benin. Sclater's guenon was formerly classified as a subspecies of the red-eared guenon.
The Preuss's monkey, also known as Preuss's guenon, is a diurnal primate that lives terrestrially in mountainous forests of eastern Nigeria, western Cameroon and Bioko in Equatorial Guinea. It was formerly classified as a subspecies of the L'Hoest's monkey.
The sun-tailed monkey from Gabon is one of the least studied primates in its habitat. It was discovered as a new species in 1988, and is classified as a guenon, which is a member of the genus Cercopithecus, but was subsequently moved to the genus Allochrocebus. It is closely related to A. preussi and A. Ihoesti, which has been determined by chromosomal analysis. Sun-tailed monkeys prefer shady areas with dense vegetation. However, even after small amounts of logging activity, populations can be unaffected. Much of their diet remains unknown and is still being studied, but they are known to prefer fruit. Their social groups are made up of one male and multiple females. Generally, the sun-tailed monkey is less aggressive towards related individuals, which is noteworthy because it has been found that, in other primate species, aggression rates towards related individuals are generally as high or higher than aggression rates towards non-related individuals. Within their social groups, individual monkeys show preference for their mothers over their fathers, and are overall less aggressive to other monkeys that they are associated with spatially.
The Allen's swamp monkey is a primate species categorized in its own genus Allenopithecus in the Old World monkey family. Phylogenetically, it is a sister clade to the guenons, but differs in dentition and habits.
De Brazza's monkey is an Old World monkey endemic to the riverine and swamp forests of central Africa. The largest species in the guenon family, it is one of the most widespread arboreal African primates. Aside from size, it can be differentiated from other cercopithecus monkeys by its orange diadem and white beard. Due to its cryptic nature, the species is not well documented in all of its habitats but has shown unique traits such as pair-bonding and aggressive behavior towards other guenons.
L'Hoest's monkey or mountain monkey, is a guenon found in the upper eastern Congo basin. They mostly live in mountainous forest areas in small, female-dominated groups. They have a dark coat and can be distinguished by a characteristic white beard.
Campbell's mona monkey, also known as Campbell's guenon and Campbell's monkey is a species of primate in the family Cercopithecidae found in the Ivory Coast, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Senegal, and Sierra Leone. It was named for Henry Dundas Campbell, in 1838. Lowe's mona monkey was previously considered a subspecies of Campbell's mona monkey. The International Union for Conservation of Nature has rated this species as being a near-threatened species because it has a wide range and is able to adapt to degraded habitats.
The red-eared guenon, red-eared monkey, or russet-eared guenon is a species of primate in the family Cercopithecidae. It is found in Cameroon, Equatorial Guinea, and Nigeria. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss, illegal bushmeat hunting and pet trade.
The lesser spot-nosed monkey, lesser spot-nosed guenon, lesser white-nosed guenon, or lesser white-nosed monkey is a species of primate in the family Cercopithecidae. It is found in Ivory Coast, Ghana, Guinea, Liberia, Sierra Leone, Togo, Guinea-Bissau, and possibly Senegal.
The crested mona monkey, also known as the crowned guenon, crowned monkey, golden-bellied guenon, or golden-bellied monkey,, is a species of African primate in the family Cercopithecidae found in west central Africa.
The northern plains gray langur, also known as the sacred langur, Bengal sacred langur and Hanuman langur, is a species of primate in the family Cercopithecidae.
The Gabon talapoin, also known as the northern talapoin, is a small species of African monkey native to riparian habitats in Cameroon, Equatorial Guinea, Gabon, the western Republic of the Congo and the far western Democratic Republic of Congo. It may have been introduced to Bioko and the Canary Islands. Classified in the genus Miopithecus, it was given the name Miopithecus ogouensis, based on the River Ogooué, distinguishing it from the other species, the Angolan talapoin, also known as Miopithecus talapoin.
Cercopithecini is a tribe of Old World monkey that includes several monkey species, including the vervet monkeys, talapoins, Allen's swamp monkeys and the guenons, all in Africa.
The tantalus monkey is an Old World monkey from Africa that ranges from Ghana to Sudan. It was originally described as a subspecies of the grivet. All species in Chlorocebus were formerly in the genus Cercopithecus. It is a common species with a wide range, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
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".
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.
The red-tailed monkey, also known as the black-cheeked white-nosed monkey, red-tailed guenon, redtail monkey, or Schmidt's guenon is a species of primate in the family Cercopithecidae.
Sciurocheirus makandensis is a species of squirrel galago native to Gabon, Africa.
