Akodontini
Akodontini is the second most speciose rodent tribe of the subfamily Sigmodontinae. It includes at least 106 living species in 19 genera and is distributed mainly in the southern half of South America, with only two genera extending into Guyana (Podoxymys) and Venezuela (Necromys). It also includes genera previously placed in tribe Scapteromyini. The following genera are now generally recognized:

Akodon
Bibimys
Blarinomys
Brucepattersonius
Deltamys
Juscelinomys
Kunsia
Lenoxus
Necromys (previously Bolomys or Cabreramys)
Neomicroxus
Oxymycterus
Podoxymys
Scapteromys
Thalpomys
Thaptomys

Chalcomys, Hypsimys, and Microxus have been synonymized under the genus Akodon. Several other genera were previously placed in Akodontini, but are now placed in a separate tribe Abrotrichini, largely on molecular grounds. Literature cited
