Type materials (4, NHRS and MNHN): Bruchus transversesignatus: Syntype female deposited in NHRS with labels: 1, “ Typus ” “In Semin. / Cassiae Bras. [Brasiliae] / Faldermann” “ Syntype / Sennius transversesignatus / (Fåhraeus, 1839) / Desig. Viana & Ribeiro-Costa, 2012”.
Bruchus carneofasciatus: Syntype deposited in MHNH with labels: “Jatahy / Goyaz” “ type ” “ carneofasciatus / n sp” “ Holotype ” “ carneofasciatus / Pic / det 70 / J. M. Kingsolver” “Museum Paris / Coll. M. Pic” “ Sennius transversesignatus / (Fåhraeus, 1839) / det J.H. Viana 2014” “ Syntype / Bruchus carneofasciatus Pic, 1927 / J. H. Viana”.
Bruchus carneofasciatus var. subapicalis: Two syntypes deposited in MHNH with labels: 1, “Corumba / Matt. Grosso” “ v. subapicalis / Pic” “ Holotype ” “ carneofasciatus / var. subapicalis / Pic / det / J. M. Kingsolver” “Museum Paris / Coll. M. Pic” “ Syntype / Bruchus carneofasciatus var. subapicalis Pic, 1930 / design. J. H. Viana”; and 1, “Corumba / Matt. Grosso” “ Bruchus carneofasciatus / Pic [...] var” “Museum Paris / Coll. M. Pic” “ Syntype / Bruchus carneofasciatus var. subapicalis Pic, 1930 / J. H. Viana”.
Remarks: The recognition of Bruchus transversesignatus was based on a female syntype already studied (Viana & Ribeiro-Costa 2013b). This species was treated as Sennius in previous papers, however no formal transference from Acanthoscelides to this genus was found. Therefore, Sennius transversesignatus (NEW COMBINATION) is formally proposed here, due mainly to the characters of the hind femur with one tooth at inner ventral margin and the internal sac of male genitalia with hinge sclerites, this last character studied from a compared male specimen deposited at DZUP.
Here is also synonymized Bruchus carneofasciatus (NEW SYNONYM) and the variety B. carneofasciatus v. apicalis (NEW SYNONYM) with Bruchus transversesignatus. In the original description, Pic does not indicate the number of specimens studied. The labels of the specimens are identical and consistent with locality data given in the original description (Brézil). One female specimen with Pic’s handwritten labels: " type " and “ carneofasciatus n sp. ", is here considered as syntype for Bruchus carneofasciatus. However only one specimen of B. carneofasciatus v. subapicalis have Pic’s label “ v. subapicalis / Pic”, both females received from the same locality label are here considered syntypes.
