Abstract
The evolutionary history of the genus Galictis in South America probably begins after the Great American Biotic Interchange. Two species are recognised: Galictis vittata and Galictis cuja. The latter are more frequently found in open areas in southern South America and the first occurs in humid forests from northern South America to Central America. Apparently, they do not occur in sympatry. Both are differentiate by the presence of a metaconid in the first inferior molar of G. vittata and for its bigger size when compared to G. cuja. The fossil record of Galictis is scarce, G. cuja is known by few specimens from Argentina, Chile and Brazil; G. vittata have only one record from Southern Brazil. The specimens related to this record were collected by Peter Lund and are housed at the Statens Naturhistoriske Museum. However, the specimens published by Lund are not fossils. Thus, it is presented here other unpublished specimens collected by Lund and housed at the same museum that we recognise as the first G. vittata fossils. Additionally, it is described here the first fossil record for G. cuja from the late Pleistocene of Brazil – an almost complete mandible recovered from sedimentary deposits from Central Brazil.
