Marañón white-fronted capuchin

The Marañón white-fronted capuchin (Cebus yuracus), also called the Peruvian white-fronted capuchin or Andean white-fronted capuchin, is a gracile capuchin monkey of the upper Amazon Basin in the family Cebidae. It was once regarded as the same animal as the shock-headed capuchin, which was in turn treated as a subspecies of Humboldt's white-fronted capuchin, until Mittermeier and Rylands classified it as a separate species on the strength of genetic studies by Boubli. It lives in wet forests of the upper Amazon basin in southern Colombia, eastern Ecuador and northeastern Peru, and likely eastern Brazil. Males have a head and body length of about 43 cm and a tail of about 47 cm, while females measure about 37 cm with a tail of about 45 cm. It has sometimes been seen in mixed groups with the Ecuadorian squirrel monkey.
