Speciments of Leporinus obtusidens from two localities belonging to the Paraná river basin, been previously separated by Salto de Guaíra, named before as Sete Quedas, were cytogenetically compared. Speciments from both localities had the same diploid number of 54 chromosoma as well as the same fundamental number NF=108, for both sexes with the presence of a sexual chromosoma system of ZZ/ZW type. It was also verified a couple of RONs, been localized in the first couple of chromosoma, in terminal position in the short arm.
