Marañón white-fronted capuchin
The Marañón white-fronted capuchin or Peruvian white-fronted capuchin is a species of gracile capuchin monkey from the upper Amazon Basin. It had been regarded as synonymous with the shock-headed capuchin, 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 with a tail length of about. Females have a head and body length about with a tail length of about.
Marañón white-fronted capuchins sometimes formed mixed groups with the Ecuadorian squirrel monkey.
