Presencia del género Ctenomys (Rodentia, Ctenomyidae) en el noreste de la provincia de Buenos Aires, Argentina

Resumen

Presence of the genus Ctenomys (Rodentia, Ctenomyidae) in northeastern Buenos Aires
province, Argentina. 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 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 XIXth century. Thus, the record of living Ctenomys in northeastern Buenos Aires province provide
new interesting clues about the biogeography of this genus in the area.
