The Roloway monkey (Cercopithecus roloway) is a species of Old World monkey found in a small area of eastern Côte d'Ivoire and the forests of Ghana, between the Sassandra and Pra Rivers.[1]
The Roloway monkey is similar to other species of guenons but is distinguished by its lengthy beard. The Roloway Monkey's coat and face are predominantly black, while the throat and the interior side of its arms are white, and its hips and back are orange. The body length varies between 40 and 55 centimetres and its weight is between 4 and 7 kilograms.
The species is arboreal, and forms social groups of 15 to 30 individuals. Its diet is composed of fruits, flowers, seeds and insects.
The Roloway monkey is among the most threatened primates on the African continent, although exact figures for the species are not available. Recent surveys could not find evidence of it in Ghana's Bia National Park, where it was probably eliminated between mid 1970s and 1990. There are estimates are that there probably has been a population decline of at least 80% over the last three generations.[2] The species is listed as one of "The World's 25 Most Endangered Primates."[3]
The Roloway monkey was previously considered a subspecies of the Diana monkey (Cercopithecus diana).[1]
