See text The guenons (UK: /ɡəˈnɒnz/, US: /ˈɡwɛn.ənz/) are Old World monkeys of the genus Cercopithecus (/ˌsɜːrkəˈpɪθəkəs/).

Nonetheless, the use of the term guenon for monkeys of this genus is widely accepted.

[citation needed] All members of the genus are endemic to sub-Saharan Africa, and most are forest monkeys.

[2] 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 designates only the females.

[3] The three species such as the L'hoest's monkey, Preuss's monkey and the sun-tailed monkey were formerly included in the genus and now listed in a different genus Allochrocebus[1][4][5] The genus Cercopithecus, derived from the Ancient Greek terms κέρκος (kérkos, “tail”) and πίθηκος (píthēkos, "ape"), was named by Carl Linnaeus in 1758.
