The Peruvian white-fronted capuchin[1] or Marañón white-fronted capuchin (Cebus yuracus) is a species of gracile capuchin monkey native to the upper Amazon basin.
- It was synonymous with the shock-headed capuchin (Cebus cuscinus), later considered a subspecies of the Humboldt’s white-fronted capuchin, but was classified as a separate species by Mittermeier and Rylands based on Boubli’s genetic studies.
- The Peruvian white-fronted capuchin is gray on the forehead, the sides of the face, the chest, and the outer sides of the arms.
- It resembles Spix’s white-fronted capuchin (Cebus unicolor). Still, its overall color is ochre-brown, contrasting strongly with the gray or buff on the outside of the forelegs.
- The flanks are lighter. Male species have a head and body length of around 43 cm (17 in) with a tail length of around 47 cm (19 in) while female metrics are 37 cm (15 in) and 45 cm (18 in), respectively.
