| A new tribe of sigmodontine rodents is formally defined and diagnosed. The tribe contains the extant genera Abrothrix (including Chroeomys), Chelemys, Geoxus, Pearsonomys, and Notiomys, a group of taxa distributed in the central and southern Andes and lowlands both east and west of the cordillera. The new tribe presents a unique combination of characters including nasals and premaxilla usually projected anterior to the incisors, moderately trumpeted; zygomatic plate with upper free border reduced or obsolete; and third upper molar reduced and sub-cylindrical in out-line with an internal ring-like enamel fossette. Molecular phylogenetic analyses indicate that Abrothrix is sister to a clade containing the remaining genera of the new tribe. |

| Un estudio detallado del itinerario seguido por J. B. Hatcher y O. A. Peterson en las nacientes del río Chico, Santa Cruz, Argentina, permite discutir la procedencia geográfica de los holotipos de Ctenomys robustus J. Allen, 1903, Ctenomys sericeus J. Allen, 1903, Oxymycterus microtis J. Allen, 1903, Reithrodon hatcheri J. Allen 1903, Euneomys petersoni J. Allen, 1903 y Notiomys vestitus alleni Osgood, 1925. De esta forma se discute y restringen sus terrae typicae contribuyendo al conocimiento de la fauna de roedores patagónicos. |
