Remarks
There is no morphological difference between the holotype of M. fragosoi (Fig. 2B) and the lectotype of M. signatellus (Fig. 11B). Despite small differences in body colour between M. signatellus and M. signatellus imperfectus, there are no conspicuous differences in the external morphology and the morphology of their male genitalia. We have also observed that M. signatellus is morphologically similar to M. lacertosus (Fig. 31E) based on similarities of their penile flagellum and body color.
