Distribution Peru, North Brazil. Remarks The dissected female of M. pebasensis has the pronotal black spot slightly “split”, resembling that of M. separandus (Fig. 10F). In fact, M. pebasensis, M. separandus, M. egae (Fig. 6C), M. decoratus (Fig. 13B) and M. hilaris (Fig. 31B) are morphologically similar, based on their colour pattern, body shape and morphology of male genitalia. However, we noted a few differences in the sclerotization of the penile flagellum and flagellar head morphology. These species may be synonyms, a decision that is not possible to take before examining more specimens and determining whether their variations are diagnostic for keeping species separated or constitute infraspecific variations of a single species.
