Río Cesar white-fronted capuchin

The Río Cesar white-fronted capuchin (Cebus cesarae) is a species of gracile capuchin monkey from the Río Cesar Valley in northern Colombia. It had previously been considered a subspecies of the white-fronted capuchin (C. albifrons). Genetic analysis by Jean Boubli in 2012 revealed that the Río Cesar white-fronted capuchin is actually more closely related to the Colombian white-faced capuchin (C. capucinus) than it is to C. albifrons. Some authors regard it to be a subspecies of the varied white-fronted capuchin (C. versicolor cesarae).

The Río Cesar white-fronted capuchin lives in dry semi-deciduous forest, gallery forest and mangroves. Its fur is light colored. Males have a head and body length between 30.8 and 40.7 cm with a tail length of between 41.9 and 49.5 cm. Females have a head and body length between 35.3 and 38.5 cm with a tail length of between 46.1 and 50 cm.
