Description:

Cytogenetic analyses were performed in 39 specimens of Delomys trapped in six localities distributed along the Atlantic forest range of the genus. Only two karyotypic forms were found: 2n = 72, FN = 90 to the north and 2n = 82, FN = 80 to the south, with an overlapping area in São Paulo and Parana states. No hybrids were found and given the large difference in karyotype it is likely that any hybrids produced would be infertile. Based on the skin coloration and type localities of the species described it is suggested that the 2n = 72 taxon corresponds to Delomys sublineatus and the 2n = 82 form to D. dorsalis.
