North Brazil.

Remarks

The examined specimens of M. reticulatus differ from the holotype of M. lopesi ( Fig. 2C View Fig ) only in having the basal elytral fascia interrupted and the body length slightly larger. Two dissected individuals have body colour similar to that of M. reticulatus and are males, whereas the holotype of M. lopesi is a female. It should be evaluated whether such a small variation in colour is a sexual dimorphism. A similar example of sexual dimorphism related to colour variation can be found in M. chilensis Crotch (see Pecci-Maddalena & Lopes-Andrade 2017).
