Remark. Bruchus muricatus Sharp, 1885 is here transferred to Sennius due the hind femur with one tooth at inner ventral margin, and internal sac of male genitalia with hinge sclerites. The boundary between the genera Megasennius (monotypic) and Sennius was not supported in the cladistic analysis of the genus Sennius (Viana, 2014) . Except for the crossed hinge sclerites in male genitalia, other diagnostic characters described by Whitehead & Kingsolver (1975a) for Megasennius , such as an expanded postocular lobe, teeth near the base of the elytral striae, hind femur with large spine, hind tibia with long mucro, have been described in different combinations of characters for some South American Sennius species (Viana & Costa Ribeiro-2013a, b, 2014). Therefore this species is here treated as Sennius muricatus (NEW COMBINATION) and, as Megasennius is monotypic and Sennius muricatus is its type species, here Megasennius is also synonymized with Sennius (NEW SYNONYM).
