Abstract
The karyotype of the catfish,Parasilurus aristotelis, from Lake Trichonis, Greece, shows that the species has a diploid chromosome number of 2n = 58. Comparison with published data on the karyotypes of other species belonging toParasilurus shows the same chromosome number but different arm numbers. Reported karyological data of the European populations ofSilurus indicate that they have a diploid number of 2n=60. A reduction in chromosome number is assumed to be connected with speciation and, therefore,Parasilurus probably forms a separate group from that ofSilurus.
