C421D67B7E17FFB45ACAF9EDBF1AFE57.taxon	discussion	Remarks. Sennius infractus Johnson & Kingsolver, 1973 was originally described based only on a female collected in Honduras. There is an error in the MCZ catalog number for this specimen, 31966, in Johnson & Kingsolver (1973) and the correct catalog number is MCZ 32916 (MCZ Online Database). Later, Johnson (1984) described the male genitalia of specimens from the same data collection as the female holotype, and indicated it as not belonging to Sennius, but did not indicate its proximity with species of any other genus. In this study male specimens from USNM described by Johnson (1984) with the same data as the holotype were examined, and here this species is here transferred to Acanthoscelides, as Acanthoscelides infractus (NEW COMBINATION), due to proximity with species of megacornis group (Johnson 1990 b) and the lack of hinge sclerites in the internal sac of male genitalia.	en	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).

C421D67B7E14FFB45ACAFE4DBDF5FB24.taxon	discussion	Remarks. In the original description, Fåhraeus (1839) did not quote the number of studied specimens. Five specimens were received from NHRS, three labeled with the same data as in the original description, “ Carthagenam – Columbiae ” and “ Coll. Chevrol ”, one specimen with labels “ Colum / bia ” “ Coll. Chevrol ” and one specimen with the " Columbia " label and with a numbered old label (“ 237 ”) corresponding to the numbered label in a specimen with " Carthagenam — Columbiae " label. Therefore, the best preserved male specimen is here designated as the lectotype. In this study, Bruchus aequinoctialis is transferred to Sennius, as Sennius aequinoctialis (NEW COMBINATION), due mainly by the presence of the hind femur with one tooth at the inner ventral margin and hinge sclerites in the internal sac of the male genitalia.	en	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).

C421D67B7E14FFB45ACAFADFBA8EF88E.taxon	discussion	Remark. In the original description, Pic does not indicate the number of specimens studied. One specimen was received from MNHN, here designated as a lectotype, with location data identical to what was given in the original description (Amazones) and Pic’s labels " type " and " amazonicus n sp ". Santos et al. (1997) cited Acanthoscelides amazonicus as belonging Sennius but no paper was found with this transference. Here it is formally transferred to Sennius, as Sennius amazonicus (NEW COMBINATION), due mainly to the following characters: hind femur with one tooth at inner ventral margin, and internal sac of male genitalia with hinge sclerites.	en	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).

C421D67B7E15FFB55ACAFF06BB41FBE2.taxon	discussion	Remarks. In the original description of Bruchus batesii, Jekel indicated only one specimen was studied. This specimen was received from BMNH, with labels identical to what was given in the original description, including Jekel's label “ Bruchus / batesii Jekel / Ins. Saund. ”. A label was included to explicitly indicate this specimen as holotype. The female type of Bruchus batesii is in poor condition, with glue covering the ventral surface, partially covering the head and the lateral body, and there is a broken tooth on the hind femur. Only the external morphology was studied and compared with other Sennius species, since the type specimen of Bruchus batesii is a female. In Blackwelder’s catalog (1946), the specific name Acanthoscelides batesii (Fåhraeus, 1839) was misspelled as A. batesi, with the subsequent paper (Udayagiri & Wadhi, 1989) propagating this error. Following the instructions of ICZN (1999, Article 33.4), this species is here treated as Sennius batesii (NEW COMBINATION) based mainly on the characters: hind femur with one tooth at inner ventral margin, and internal sac of male genitalia with hinge sclerites. I consider B. subaenescens Pic, 1931 (NEW SYNONYM) to be a subjective synonym of Bruchus batesii since there are no remarkable external differences. In the original description of Bruchus subaenescens, Pic does not indicate the number of specimens studied but Kingsolver (1976) designated as holotype the specimen studied.	en	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).

The type material of Bruchus diosanus, here designated as a lectotype, is in poor condition with little pubescence remaining. However, it was possible to study the male genitalia and here this species is here treated as Sennius diosanus (NEW COMBINATION) based mainly on the character: internal sac of male genitalia with hinge sclerites.	en	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).

C421D67B7E13FFB35ACAFDF4BBA2FADD.taxon	discussion	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 (1975 a) 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- 2013 a, 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).	en	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).

C421D67B7E10FFB05ACAFDB5BF51FAC1.taxon	discussion	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).	en	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).

One specimen with Pic’s handwritten labels: " type " and “ subdiversicolor n sp. ", is here designed as the lectotype of Bruchus subdiversicolor. Bruchus subdiversicolor v. innigripes: In the original description, Pic (1931 c) does not indicate the number of specimens studied. Two specimens were received, both with labels identical and consistent with the locality data given in the original description (Brazil), but only one with Pic’s labels “ v. innigripes / <illegible letters>, designed as lectotype. Here the variety B. subdiversicolor v. innigripes (NEW SYNONYM) is synonymized with Bruchus subdiversicolor.	en	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).

C421D67B7E11FFBE5ACAFD1EBC5CFF27.taxon	discussion	Remarks: The recognition of Bruchus transversesignatus was based on a female syntype already studied (Viana & Ribeiro-Costa 2013 b). 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.	en	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).

C421D67B7E1EFFBE5ACAFEDDBF01FBB1.taxon	discussion	Remarks. The recognition of Sennius trinotaticollis was based on Viana & Ribeiro-Costa (2013 b), and the homotype determined by J. M. Kingsolver in 1971 deposited at MNHN. Bruchus diversicollis (NEW SYNONYM) is here synonomized with Bruchus trinotaticollis. Both names were proposed by Pic in the same work, so I prioritize Bruchus trinotaticollis since this name is more common in literature (Principle of the First Reviser, article 24.2 of the ICZN 1999). In the original description, Pic does not indicate the number of specimens studied, however one specimen was received from MNHN with location data identical to what is given in the original description, Cayenne. This specimen is here considered as a lectotype of B. diversicollis.	en	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).

C421D67B7E1EFFBE5ACAFB53BD82F989.taxon	discussion	Remarks. The recognition of Bruchus ventralis was based on personal notes by John M. Kingsolver on this type specimen and a male homotype deposited at USNM and identified by J. M. Kingsolver in 1979. Here, Sennius ventralis (NEW COMBINATION) is formally proposed due mainly to the hind femur with one tooth at inner ventral margin, and internal sac of male genitalia with hinge sclerites.	en	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).
