The common patas monkey, also known as the wadi monkey or hussar monkey, is a ground-dwelling monkey distributed over semi-arid areas of West Africa, and into East Africa.
The Diana monkey is an Old World monkey found in the high canopy forests in Sierra Leone, Liberia, and western Côte d’Ivoire. Named for its white brow which is said to resemble the bow of the Roman goddess Diana, this black-grey guenon has a white throat, crescent-shaped browband, ruff and beard.
The guenons are Old World monkeys of the genus Cercopithecus. 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.
The blue monkey or diademed monkey is a species of Old World monkey native to Central and East Africa, ranging from the upper Congo River basin east to the East African Rift and south to northern Angola and Zambia. It sometimes includes Sykes', silver, and golden monkeys as subspecies.
The Dryas monkey, also known as Salonga monkey, ekele, or inoko, is a little-known species of Old World monkey found only in the Congo Basin, restricted to the left bank of the Congo River. It is now established that the animals that had been classified as Cercopithecus salongo were in fact Dryas monkeys. Some older sources treat the Dryas monkey as a subspecies of the Diana monkey and classify it as C. diana dryas, but it is geographically isolated from any known Diana monkey population.
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 mona monkey is an Old World monkey that lives in western Africa between Ghana and Cameroon. The mona monkey can also be found on the island of Grenada as it was transported to the island aboard slave ships headed to the New World during the 18th century. This guenon lives in groups of up to thirty-five in forests. It mainly feeds on fruit, but sometimes eats insects and leaves. The mona monkey has brown agouti fur with a white rump. Its tail and legs are black and the face is blue-grey with a dark stripe across the face. The mona monkey carries food in cheek pouches.
The Hamlyn's monkey, also known as the owl-faced monkey, is a species of Old World monkey that inhabits the bamboo and primary rainforests of the Congo. This species is exceedingly rare and known only from a few specimens; little is known about it. However these specimens tend to be widely dispersed throughout the eastern part of Congo, from the Epulu River to the Lukuga River and from the Congo River to the Kabale Forest, with one example in northwestern Rwanda. Geographically it corresponds quite closely to another species of monkey, L'Hoest's monkey C. lhoesti. It travels on the ground, and researchers think that it may be awake primarily by night.
The greater spot-nosed monkey or putty-nosed monkey is one of the smallest Old World monkeys. It is a guenon of the C. mitis group, native to West Africa and living to some extent in rain forests, but more often in the transition zone between rain forest and savannah. It is primarily arboreal and often associates with monkeys of other species. Both their common names come from the monkeys' prominent white nose.
The moustached guenon or moustached monkey is a species of primate in the family Cercopithecidae. It is found in Angola, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, and Gabon.
The red-eared guenon, also called red-eared monkey, or russet-eared guenon is a primate species in the family Cercopithecidae. It is native to subtropical and tropical moist lowland forests in Cameroon, Equatorial Guinea and Nigeria. It is listed as Vulnerable on the IUCN Red List and is threatened by habitat loss, illegal bushmeat hunting and pet trade.
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 golden monkey is a subspecies of the blue monkey. It is an Old World monkey found in the Virunga volcanic mountains of Central Africa, including four national parks: Mgahinga, in south-west Uganda; Volcanoes, in north-west Rwanda; and Virunga and Kahuzi-Biéga, in the eastern Democratic Republic of Congo. It is restricted to highland forest, especially near bamboo.
Sykes' monkey, also known as the white-throated monkey or Samango monkey, is a subspecies of the blue monkey. It is an Old World monkey found between Ethiopia and South Africa, including south and east Democratic Republic of Congo. It is named after English naturalist Colonel William Henry Sykes (1790-1872), and has a large white patch on the throat and upper chest, and a grizzled cap.
The Bale Mountains vervet is a terrestrial Old World monkey endemic to Ethiopia, found in the bamboo forests of the Bale Mountains. All species in Chlorocebus were formerly in the genus Cercopithecus. The Bale Mountains vervet is one of the least-known primates in Africa. They avoid tree-dominated and bushland areas as their habitat. These monkeys mainly reside in the bamboo forest of the Bale Mountains due their dietary specialization on bamboo, but other factors, such as climate, forest history, soil quality, and disease, are likely to play a role in their choice to inhabit this area. The Bale Mountains vervet have a very quiet behavior and tend to flee when encountering a human being. It is also known as the Bale monkey.
Lowe's mona monkey is an Old World monkey in the family Cercopithecidae found from the Ivory Coast to Ghana. It was previously classified as a subspecies of Campbell's mona monkey C. campbelli.
Dent's mona monkey is an Old World monkey in the family Cercopithecidae found in the Democratic Republic of the Congo, the Congo, Rwanda, western Uganda, and the Central African Republic. It was previously classified as a subspecies of Wolf's mona monkey C. wolfi. Verifying whether they are a subspecies or a separate species is dependent on further research that needs to be done at the contact zone of Cercopithecus denti, Cercopithecus wolfi, and Cercopithecus wolfi elegans, in the forests between the Lualaba and Lomani rivers, south of the junction of the Congo and the Lomani rivers.
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.
