The Sierra de Perijá white-fronted capuchin monkey[1] (Cebus leucocephalus) is a species of gracile capuchin monkey native to Venezuela and Colombia.
- It was formerly considered a subspecies of Humboldt’s white-fronted capuchin. Still, it was reclassified as a distinct species by Rylands and Mittermeier in 2013 based on genetic studies by Jean Boubli.
- Males have a head and body that vary between 37 and 40.7 cm (14.6 and 16.0 in) with a tail length of between 39.2 and 49.9 mm (1.54 and 1.96 in).
- Sierra de Perijá white-fronted capuchins have a dark brown body with lighter hair on the ventral side (belly area) and around the face.
- Their expressive faces are pink, with dark brown eyes and large nostrils above their mouths.
- Their front and hind legs are roughly the exact sizes, which is considered an adaptation since they are more ground-traveling than other New World primates.
- Its tail is semi-prehensile and fully covered in hair. Their fingers are short with pseudo-opposable thumbs, and they can move all their fingers independently of the others.
