Resumen:
Abstract. Extinct dinomyids (Rodentia, Hystricognathi) are yet poorly known. Among them, Drytomomys Anthony, 1922 has a particular interest from a biogeographical perspective, since it is one of the few extinct mammal genera recorded both in the “Mesopotamian” (= “Conglomerado osífero”, Late Miocene, Northeast of Argentina) and Laventan (Middle Miocene, La Venta, Colombia) faunas. The comparative study of the holotype of “Olenopsis” typicus Scalabrini in Ameghino, 1889, coming from the “Conglomerado osífero”, enables the allocation of this species to genus Drytomomys. The assignment of specimens recovered from La Venta fauna to D. aequatorialis is confirmed. The geographical distribution of Drytomomys suggests a biogeographical relationship of the Northeast of Argentina with the North of South America during the Miocene.
