Remarks

The primary types of M. dorsofasciatus Lacordaire, 1842 and M. nugator Lacordaire, 1842 were not found. However, based on their original descriptions and examination of identified specimens from historical collections, we noted that M. dorsofasciatus and M. nugator differ mainly in the width of the elytral bands, which are wide on the former and narrow on the latter. The male genitalia of both species have the same structural pattern.
