. . . "New World monkeys are the five families of primates that are found in Central and South America and portions of Mexico: Callitrichidae, Cebidae, Aotidae, Pitheciidae, and Atelidae. The five families are ranked together as the Platyrrhini parvorder and the Ceboidea superfamily, which are essentially synonymous since Ceboidea is the only living platyrrhine superfamily.Platyrhini means flat-nosed, and their noses are flatter than those of other simians, with sideways-facing nostrils."@en . .
