Shock-headed capuchin

The shock-headed capuchin (Cebus cuscinus) is a species of gracile capuchin monkey from Bolivia and Peru. It was previously classified as a subspecies of the Humboldt's white-fronted capuchin (C. albifrons), but in 2013 Mittermeier and Rylands elevated it to a separate species, following genetic studies by Boubli et al. in 2012 and Lynch Alfaro et al. in 2010.

The shock-headed capuchin lives in lowland and seasonally inundated forests of the upper Amazon Basin, as well as montane forests of the western Andes Mountains up to elevations of 1800 m.  Males have a head and body length of about 40 cm with a tail length of about 44 cm. Females have a head and body length between 39 and 46 cm with a tail length between 39 and 47.5 cm.
