The family Cebidae contains 11 genera 58 species (following most recent authors, we exclude the marmosets and tamarins and place them in their own family, the Callitrichidae). Cebids are a strictly American group, currently found from southern Mexico south to northern Argentina. They have been in South America since at least the early Oligocene, when they probably arrived via overwater rafting from Africa.
