Mangabeys are an entirely African assemblage of cercopithecid monkeys, traditionally grouped together in the genus Cercocebus Geoffroy Saint-Hilaire, 1812.    From Wordnik.com.  [Archive 2006-06-01] Reference

This division of the mangabeys has been mostly accepted by mammalogists, but not universally so (McKenna & Bell 1997 still treat all mangabeys as the single genus Cercocebus, for example).    From Wordnik.com.  [Archive 2006-06-01] Reference

The western sooty mangabey (Cercocebus torquatus lunulatus), the western subspecies of chimpanzee (Pan troglodytes verus EN), and the diana monkey (EN) are all in need of protection from this threat.    From Wordnik.com.  [Eastern Guinean forests] Reference

In comparison crowned guenon (Cercopithecus pogonias EN), chimpanzee (Pan troglodytes, EN), agile mangabey (Cercocebus agilis), and gray-cheeked mangabey (Lophocebus albigena) occur only on the right bank.    From Wordnik.com.  [Eastern Congolian swamp forests] Reference

For example, the western and eastern subspecies of sooty mangabey (Cercocebus torquatus atys, C.t. lunulatus) and of diana monkey (Cercopithecus diana diana, C.d. roloway) are separated by the Sassandra River.    From Wordnik.com.  [Eastern Guinean forests] Reference

Three species of primates are endemic to the Eastern Arc Mountains and Southern Rift, the Sanje mangabey (Cercocebus sanjei, EN), the Udzungwa red colobus (Procolobus gordonorum, VU) and the mountain dwarf galago (Galagoides orinus).    From Wordnik.com.  [Biological diversity in the Eastern Afromontane] Reference

Non-human primates are also diverse and include endemic subspecies of the Diana monkey (Cercopithecus diana diana, EN), red colobus (Procolobus badius badius), lesser spot-nosed monkey (Cercopithecus petaurista petaurista), and sooty mangabey (Cercocebus torquatus atys).    From Wordnik.com.  [Western Guinean lowland forests] Reference

Good observations were finally made of the Kipunji in December 2003, and it now turned out that a monkey population reported in 2001 from the Ndundulu Forest Reserve, misidentified as Sanje mangabeys Cercocebus sanjei (itself only discovered in 1979), were actually reports of the Kipunji.    From Wordnik.com.  [Archive 2006-06-01] Reference

However, this ecoregion was divided from the Upper Guinea lowland forest ecoregion west of the Sassandra River, which forms a biogeograpic barrier for species and subspecies, including a large number of amphibians, as well as Colobus vellerosus, Cercopithecus (m.) lowei, and Cercocebus atys lunulatus.    From Wordnik.com.  [Eastern Guinean forests] Reference

There are 11 species of monkey including anubis baboon Papio anubis, diana monkey Cercopithecus Diana (EN), green monkey Cercopithecus aethiops, mona monkey C. mona, lesser white-nosed monkey C. petaurista, white collared mangabey Cercocebus torquatus lunulatus, black and white colobus Colobus polykomos and chimpanzee Pan troglodytes (EN).    From Wordnik.com.  [Comoé National Park, Côte d'Ivoire] Reference

I like Jonathan Kingdon’s use of the term ‘drill-mangabey’ for the terrestrial Cercocebus species, and of ‘baboon-mangabey’ for the arboreal Lophocebus species, and I’ll use them from hereon.    From Wordnik.com.  [Archive 2006-06-01] Reference

Consequently, it has been widely agreed that the two arboreal species should be split from Cercocebus and given their own genus, Lophocebus (originally coined by Palmer in 1903 to replace Semnocebus Gray, 1870.    From Wordnik.com.  [Archive 2006-06-01] Reference
