'''New World monkeys''' are the five families of [[primate]]s that are found in the tropical regions of [[Mexico]], [[Central America|Central]] and [[South America]]: [[Callitrichidae]], [[Cebidae]], [[night monkey|Aotidae]], [[Pitheciidae]], and [[Atelidae]]. The five families are ranked together as the '''Ceboidea''' ({{IPAc-en|s|ə|ˈ|b|ɔɪ|d|i|.|ə}}), the only extant superfamily in the [[parvorder]] '''Platyrrhini''' ({{IPAc-en|p|l|æ|t|ᵻ|ˈ|r|aɪ|n|aɪ}}).<ref>{{cite web| url = http://www.chimpanzoo.org/ceboidea.html| title = Platyrrhini and Ceboidea| publisher = ChimpanZoo| year = 2005| access-date = 19 July 2009| archive-url = https://web.archive.org/web/20080515074123/http://www.chimpanzoo.org/ceboidea.html| archive-date = 2008-05-15}}</ref>

Platyrrhini is derived from the [[Greek language|Greek]] for "broad nosed", and their noses are flatter than those of other simians, with sideways-facing nostrils. Monkeys in the family Atelidae, such as the [[spider monkey]], are the only primates to have [[prehensile tail]]s. New World monkeys' closest relatives are the other [[simian]]s, the [[Catarrhini]] ("down-nosed"), comprising [[Old World monkey]]s and [[ape]]s. New World monkeys descend from African simians that colonized South America, a line that split off about 40 million years ago.<ref name="Sellers">{{cite web | url = https://eclass.uoa.gr/modules/document/file.php/BIOL121/ΕΠΙΛΕΓΜΕΝΑ%20ΚΕΙΜΕΝΑ/PrimateEvolution.pdf| title = Primate Evolution | access-date = 2008-10-23 | last = Sellers | first = Bill | date = 2000-10-20 | publisher = University of Edinburgh | pages = 13–17}}</ref>
