Remarks
The lectotype of Mycotretus derasofasciatus Kuhnt is morphologically identical to the lectotype of M. scitulus. The lectotype of M. nubifer Casey is slightly wider and has a smoother contour of the elytral medial band (not serrated) compared to the two former species. We dissected male individuals of those distinct phenotypes (and from widely separated localities, see above), and observed no morphological difference in their male genitalia. Aside from that, we noted several representatives of M. scitulus, housed in the DZUP collection, from distinct localities in the Neotropical region, as follows: “Tiriós”, “Jacaré P.N. Xingu” (Northeast Brazil), “Parque Soretama”, “Represa Rio Grande” (Southeast Brazil), and others. Such specimens and their labels were not examined in more details and were not included in the examined material listed above. These geographical records reveal that M. scitulus is a broadly distributed species in the Neotropical region, occurring from Mexico to Southeast Brazil.
