Distribution
South Brazil.
Remarks
1) There was one unlabelled specimen close to the lectotype in the UMZC collection. However, we do not know whether it is a syntype. 2) The unique (and very small) difference between the lectotypes of M. discipennis and M. sexlineatus is the length of the elytral stripes, which is shorter in the former than in the latter. Similarly, the central elytral spot of the lectotype of M. deyrollei is shorter than that of M. discipennis conductus. Aside from colour variation, there is no other external morphological difference in the examined specimens and the morphological pattern of their male genitalia is the same.
