The guenons ( // or // ) 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.
All members of the genus are endemic to sub-Saharan Africa, and most are forest monkeys. Many of the species are quite local in their ranges, and some have even more local subspecies. Many are threatened or endangered because of habitat loss. The species currently placed in the genus Chlorocebus , such as vervet monkeys and green monkeys, were formerly considered as a single species in this genus, Cercopithecus aethiops.
In the English language, the word "guenon" is apparently of French origin.In French, guenon was the common name for all species and individuals, both males and females, from the genus Cercopithecus. In all other monkey and apes species, the French word guenon only designates the females. The 3 species such as the L'hoest's monkey, Preuss's monkey and the sun-tailed monkey were formely included in the genus and now listed in a different genus Allochrocebus
The red-tailed monkey (Cercopithecus ascanius) is known to hybridize with the blue monkey (C. mitis) in several locations in the wild in Africa.
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 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.
Mount Cameroon is an active volcano in the South West region of Cameroon next to the city of Buea near the Gulf of Guinea. Mount Cameroon is also known as Cameroon Mountain or Fako or by its indigenous name Mongo ma Ndemi. It is the highest point in sub-Saharan western and central Africa, the fourth-most prominent peak in Africa, and the 31st-most prominent in the world.
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.
Wolf's mona monkey, also called Wolf's guenon, is a colourful Old World monkey in the family Cercopithecidae. It is found in central Africa, primarily between the Democratic Republic of the Congo and Uganda. It lives in primary and secondary lowland rainforest and swamp forest.
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 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.
Spot-nosed monkey refers to two species in the genus Cercopithecus (guenons):
The roloway monkey is an endangered species of Old World monkey endemic to tropical West Africa. It was previously considered a subspecies of the Diana monkey. It is classified as Critically Endangered due to habitat loss and continued hunting for the bushmeat trade. The roloway monkeys are mainly arboreal species, for the most part inhabiting forests in Ghana and some reserves in South-Eastern Côte-D'Ivoire. More specifically studies have shown that the C. diana roloway is mostly concentrated in Tanoé forest because of their heavy threats to extinction.
Sykes' monkey, also known as the white-throated monkey or Samango monkey, 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 been considered conspecific with the blue monkey, but has a large white patch on the throat and upper chest, and a grizzled cap.
Spot-nosed guenon may refer to either of two species in the Guenon genus:
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.
Lomami National Park is a national park located in the Democratic Republic of Congo in Central Africa. Situated within the middle basin of the Lomami River, it straddles the Provinces of Tshopo and Maniema with a slight overlap into the forests of the Tshuapa and Lualaba river basins. The National Park was formally declared on 7 July 2016. It is the 9th national park in the country and the first to be created since 1992.
