Abstract
The first record of the Neolicaphrium recens Frenguelli (Mammalia, Litopterna) from Pleistocene deposits of the Río Dulce, Rio Hondo Department, Santiago del Estero Province, Argentina, is reported. The morphology and morphometry observed in the specimen MPAT073 is coincident with the diagnostic characteristics of that species. This finding represents the northernmost and westernmost record of the species, and thus extends its geographical distribution. Although the fossil was found in the recent sands of the Río Dulce, geological data suggest that its original source is a still unnamed Pleistocene stratigraphic unit.
