Akodontini [SEP] parent taxon
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"
their distinction from Akodontini, and in 1999 a study analyzing sequences of the mitochondrial cytochrome "b" gene found further evidence for the distinction between Akodontini and this group and proposed the name Abrotrichini for the latter. The name Abrotrichini remained formally unavailable under the International Code of Zoological Nomenclature, however, because their proposal had been conditional. Thus, the clade remained without a valid name and for this reason it was included in Akodontini in the 2005 third edition of "Mammal Species of the World". Other phylogenetic studies, which
