Peruvian white-fronted capuchin
The Marañón white-fronted capuchin or Peruvian white-fronted capuchin (Cebus yuracus ) is a species of gracile capuchin monkey from the upper Amazon Basin. It had been regarded as synonymous with the shock-headed capuchin (C. cuscinus ), which was then considered a subspecies of Humboldt's white-fronted capuchin, but it was classified as a separate species by Mittermeier and Rylands based on genetic studies by Boubli.
The Marañón white-fronted capuchin lives in wet forests of the upper Amazon basin in southern Colombia, eastern Ecuador, northeastern Peru and likely eastern Brazil. Males have a head and body length of about 43 cm (17 in) with a tail length of about 47 cm (19 in). Females have a head and body length about 37 cm (15 in) with a tail length of about 45 cm (18 in).
Marañón white-fronted capuchins sometimes formed mixed groups with the Ecuadorian squirrel monkey.
