Sigmodontinae

See text The rodent subfamily Sigmodontinae 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.Their distribution includes much of the New World, but the genera are predominantly South American, such as brucies.The genera Wiedomys and Sigmodon are generally placed in their own tribe, and the "phyllotines" Irenomys, Punomys, Euneomys, and Reithrodon are considered incertae sedis.This name in turn derives from the Greek roots for "S-tooth" (sigm- for "S" and odont- for "tooth", as in orthodontist) for the characteristic of the molars having an S-shape when viewed from above.
