%X Karyotypes are shown for Leiodes calcarata (Erichson, 1845), Catops coracinus Kellner, 1846, Cantabrogeus luquei (Salgado 1993), Espanoliella luquei Salgado & Fresneda, 2005, Fresnedaella lucius Salgado, Labrada & Luque 2011, Notidocharis uhagoni (Sharp, 1872), Quaestus (Quaesticulus) pasensis Salgado, Labrada & Luque, 2010, all of which are shown to have a diploid number of 20 autosomes plus Xy (¡á) or XX (¡â) sex chromosomes, as well as an as yet undescribed triploid species of the genus Cantabrogeus Salgado, 2000. These results are contrasted with published information, all on Leptodirini, which lists 10 species asdiploid numbers of 22 + Xy or XX. It is shown that the higher chromosome number (n = 11 + X or y) previously reported refers exclusively to the more derived Leptodirini (¡°infraflagellates¡±) whereas the lower number (n = 10 + X or y) refers to the less derived surface-dwelling forms and the less derived Leptodirini (¡°supraflagellates¡±).
