Shock-headed capuchin

The shock-headed capuchin (Cebus cuscinus) is a gracile capuchin monkey from Bolivia and Peru, in the family Cebidae. It was previously classified as a subspecies of Humboldt's white-fronted capuchin, and in 2013 Mittermeier and Rylands raised it to a separate species, following genetic studies by Boubli and colleagues in 2012 and by Lynch Alfaro and colleagues in 2010. It lives in lowland and seasonally inundated forests of the upper Amazon Basin and in montane forests of the western Andes Mountains up to elevations of 1,800 m. Males have a head and body length of about 40 cm with a tail of about 44 cm, and females have a head and body length between 39 and 46 cm with a tail between 39 and 47.5 cm.
