{{main|List of platyrrhines}}
The following is the listing of the various platyrrhine families, as defined by Rylands & Mittermeier (2009),<ref name=SAP>{{cite book |vauthors=Rylands AB, Mittermeier RA|title = South American Primates: Comparative Perspectives in the Study of Behavior, Ecology, and Conservation | chapter = The Diversity of the New World Primates (Platyrrhini): An Annotated Taxonomy | publisher = Springer |veditors=Garber PA, Estrada A, Bicca-Marques JC, Heymann EW, [[Karen B.

The arrangement of the New World monkey families, indeed the listing of which groups consist of families and which consist of lower taxonomic groupings, has changed over the years. McKenna & Bell (1997) used two families: Callitrichidae and Atelidae, with Atelidae divided into Cebinae, Pitheciinae, and Atelinae.<ref name=McKennaBell>{{cite book |editor-last1=McKenna |editor-first1=M. C. |editor-last2=Bell |editor-first2=S. K. |year=1997 |title=Classification of mammals – above the species level |publisher=Columbia University Press |location=New York |pages=xii-631}}</ref>
Rosenberger (2002 following Horowitz 1999) demoted Callitrichidae to a subfamily, putting it under the newly raised Cebidae family.<ref name=Rosenberger>{{cite book |last1=Rosenberger |first1=A.

C. |title=The Primate Fossil Record |publisher=Cambridge University Press |location=Cambridge, England|bibcode=2002prfr.book.....H }}</ref>
Groves (2005) used four families, but as a flat structure.<ref name=msw3/>

One possible arrangement of the five families and their subfamilies of Rylands & Mittermeier can be seen in Silvestro ''et al.'' (2017):<ref name=Silvestro>{{cite bioRxiv |last1=Silvestro |first1=Daniele |last2=Tejedor |first2=Marcelo F. |last3=Serrano Serrano |first3=Martha L. |last4=Loiseau |first4=Oriane |last5=Rossier |first5=Victor |last6=Rolland |first6=Jonathan |last7=Zizka |first7=Alexander |last8=Antonelli |first8=Alexandre |last9=Salamin |first9=Nicolas |year=2017 |title=Evolutionary history of New World monkeys revealed by molecular and fossil data |biorxiv=10.1101/178111}}</ref>
