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).[1] 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.[2] Some authors regard it to be a subspecies of the varied white-fronted capuchin (C. versicolor cesarae).[3]
The Río Cesar white-fronted capuchin lives in dry semi-deciduous forest, gallery forest and mangroves.[1] Its fur is light colored.[1] Males have a head and body length between 30.8and with a tail length of between 41.9and.[1] Females have a head and body length between 35.3and with a tail length of between 46.1and.[1]
