An assessment of the systematics and evolution of the Akodontini, with the description of new fossil species of Akodon ( Cricetidae: Sigmodontinae).
The taxonomy and systematics of the tribe Akodontini (Cricetidae: Sigmodontinae) are dicussed and revised. The Pliocene Akodon (Abrothrix) kermacki Reig, 1978 is described in detail, with the new species A. (Abrothrix) magnus and A. (Akodon)lorenzinii from the Lower Pleistocene, and A. (Ak.) johanni...

| Sumario: | The taxonomy and systematics of the tribe Akodontini (Cricetidae: Sigmodontinae) are dicussed and revised. The Pliocene Akodon (Abrothrix) kermacki Reig, 1978 is described in detail, with the new species A. (Abrothrix) magnus and A. (Akodon)lorenzinii from the Lower Pleistocene, and A. (Ak.) johannis from the Middle Pleistocene. Also described are remains of A. (Ak.) cf. cursor and A. (Ak.) cf. iniscatus from the Middle and Upper Pleistocene, respectively. A tentative scenario of the origin and evolutionary deployment of the Akodontini is presented, including an origin in the Puna by Middle Miocene times and an indication of probable dispersal corridors. -from Author |
