AGNOLIN, Federico L.; CHIMENTO, Nicolás R.; GUERRERO, Elián  y  LUCERO, Sergio O.. Presence of the genus Ctenomys (Rodentia, Ctenomyidae) in northeastern Buenos Aires province, Argentina. Rev. Mus. Argent. Cienc. Nat. [online]. 2010, vol.12, n.1, pp.17-22. ISSN 1853-0400.

The genus Ctenomys found at the locality of Lima, in the northeastern region of Buenos Aires province, is reported in this paper. The finding of specimens of this genus is located more than 150 kilometers to the North of previous mentions for the province, being not possible its adcription to C. talarum or to any other species from the mesopotamian region of Argentina. Previous papers indicate the presence of fossil Ctenomys in several localities in northern Buenos Aires province, and suggest that the genus disappeared from this region before the XIX^th century. Thus, the record of living Ctenomys in northeastern Buenos Aires province provides new interesting clues about the biogeography of this genus in the area.

Palabras clave : Ctenomys; Holocene; Lima; Buenos Aires; Argentina.
