New Range Limits of the Sun-tailed Monkey, Cercopithecus solatus, in Central Gabon

Cercopithecus solatus is a recently discovered monkey endemic to Gabon, present in parts of the Lope National Park and the Foret des Abeilles in the center of the country. It is listed as Vulnerable on the IUCN Red List (2010) due to its restricted extent of occurrence and continuing decline in population caused by high hunting pressure. All known field observations of this species are compiled here. Data collected since 1999 show that C. solatus occurs further to the south, east, and west than was previously known, and that its extent of occurrence almost certainly includes three national parks, rather than one.
