The black-headed spider monkey (Ateles fusciceps) is a species of spider monkey, a type of New World monkey, from Central and South America. It is found in Colombia, Nicaragua and Panama. Although primatologists such as Colin Groves (****) follow Kellogg and Goldman (1944) in treating A. fusciceps as a separate species, other authors, including Froelich (1991), Collins and Dubach (2001) and Nieves (2005) treat it as a subspecies of Geoffroy's spider monkey.
