Subfamily of rodents
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. 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.
[1] 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 the
Amazon rainforest . 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
orthodont ist ) for the characteristic of the
molars having an S-shape when viewed from above.
