Viana, Jéssica Herzog, 2016, Nomenclatural changes and lectotype designations in the seed-beetle genus Sennius Bridwell: with the synonymization of Megasennius Whitehead & Kingsolver (Coleoptera: Chrysomelidae: Bruchinae), Zootaxa 4175 (3), pp. 249-260 : 255

Sennius rufopygus (Pic, 1930) , stat. n. comb n.

Bruchus carneofasciatus var. rufopygus Pic, 1930b 11 (description, distribution). Acanthoscelides carneofasciatus var. rufopygus: Blackwelder, 1946: 759 (combination, catalog); Udayagiri & Wadhi, 1989: 41 (catalog).

Type material (1, MNHN). Lectotype male with labels: “ Bruchus / alticola / Mexi<illegible letters>” “ alticola ? / <illegible letters> / var. a <illegible letters> / <illegible letters> pygid. / et une bomde / <illegible letters> / <illegible letters> ” “ v. rufopygus / Pic” “Holotype” “ carneofasciatus / var. rufopygus / Pic / det. 70 / J. M. Kingsolver” “ Sennius rufopygus / (Pic, 1930) / det. J.H. Viana 2014” “Lectotype / Bruchus carneofasciatus / v. rufopygus / Pic, 1930 / design. J. H. Viana”

Remarks. One specimen was received from the MNHN with two of Pic’s conflicting handwritten labels “ Bruchus / alticola / Mexi <illegible letters>” and " v. rufopygus / Pic ", added bellow to the second extensive label. However, I concluded that this second label, “ alticola ? / <illegible letters> / var. a <illegible letters> / <illegible letters> pygid. / et une bomde / <illegible letters> / <illegible letters>”, show the doubts about the identification as Sennius alticola ( Sharp 1885) , followed by the label identifying as " v. rufopygus / Pic ". Since the locality on the label ( Mexi ) is similar to the data given in the original description ( Mexique) of Bruchus carneofasciatus var. rufopygus and the Pic’s handwritten label " v. rufopygus / Pic ", here this specimen is designated as lectotype . The examination of the Bruchus carneofasciatus v. rufopygus lectotype showed that it is a separate species from Bruchus carneofasciatus (junior synonym of Sennius transversesignatus ). Therefore, Bruchus carneofasciatus v. rufopygus (Pic, 1930) is here proposed as Sennius rufopygus (Pic, 1930) (NEW STATUS and NEW COMBINATION).
