The rodent subfamily Sigmodontinae is one of the most diverse groups of mammals. It includes New World rats and mice, with at least 376 species. Many authorities include the Neotominae and Tylomyinae as part of a larger definition of Sigmodontinae. When those genera are included, the species count numbers at least 508. Their distribution includes much of the New World, but the genera are predominantly South American, such as brucies. They invaded South America from Central America as part of the Great American Interchange near the end of the Miocene, about 5 million years ago. Sigmodontines proceeded to diversify explosively in the formerly isolated continent. They inhabit many of the same ecological niches that the Murinae occupy in the Old World. The "Thomasomyini" from the Atlantic Forest of Brazil are generally thought to be not especially related to the "real" Thomasomyini from the northern Andes and Amazonia. The genera ''Wiedomys'' and ''Sigmodon'' are generally placed in their own tribe, and the "phyllotines" ''Irenomys'', ''Punomys'', ''Euneomys'', and ''Reithrodon'' are considered ''incertae sedis''. The name "Sigmodontinae" is based on the name of the type genus, ''Sigmodon''. This name in turn derives from the Greek roots for "S-tooth" (''sigm-'' for "S" and ''odont-'' for "tooth", as in orth''odont''ist) for the characteristic of the molars having an S-shape when viewed from above. The Sigmodontinae are divided into a number of tribes and genera: *SUBFAMILY SIGMODONTINAE * *Sigmodontalia * * *Tribe Sigmodontini * * * *Genus ''Sigmodon'' - cotton rats * * * * *Subgenus ''Sigmodon'' * * * * * *''Sigmodon hispidus'' species group * * * * * * *Allen's cotton rat, ''Sigmodon alleni'' * * * * * * *Arizona cotton rat, ''Sigmodon arizonae'' * * * * * * *Southern cotton rat, ''Sigmodon hirsutus'' * * * * * * *Hispid cotton rat, ''Sigmodon hispidus'' * * * * * * *Jaliscan cotton rat, ''Sigmodon mascotensis'' * * * * * * *Yellow-nosed cotton rat, ''Sigmodon ochrognathus'' * * * * * * *Miahuatlán cotton rat, ''Sigmodon planifrons'' * * * * * * *Toltec cotton rat, ''Sigmodon toltecus'' * * * * * * *Montane cotton rat, ''Sigmodon zanjonensis'' * * * * * *''Sigmodon fulviventer'' species group * * * * * * *Tawny-bellied cotton rat, ''Sigmodon fulviventer'' * * * * * * *Unexpected cotton rat, ''Sigmodon inopinatus'' * * * * * * *White-eared cotton rat, ''Sigmodon leucotis'' * * * * * * *Peruvian cotton rat, ''Sigmodon peruanus'' * * * * *Subgenus ''Sigmomys'' * * * * * *Alston's cotton rat, ''Sigmodon alstoni'' * * *Tribe Ichthyomyini * * * *Genus ''Anotomys'' -
