“…Sennius Bridwell, 1946 is placed in the most diverse tribe, Bruchini, which includes three subtribes (Borowiec, 1987). Sennius belongs in the Acanthoscelidina, an artificial assemblage which includes about 800 species distributed in the New and Old World and constitutes more than a half of all Bruchinae species (Silva & Ribeiro-Costa 2008). Species of Sennius feed on plants of the subtribe Cassiinae, mostly those in the genus Senna Mill., including some weeds like S. obtusifolia (Linn.)…”

Sennius Bridwell is a New World genus of Bruchinae. Most species are placed in eight groups. In this study the species of the S. abbreviatus group are reviewed based on characters of the external morphology and the male genitalia. The group includes 14 species, two of which are new: Sennius abbreviatus (Say, 1824), S. bondari (Pic, 1929), S. durangensis Johnson & Kingsolver, 1973, S. lawrencei Johnson, 1977, S. lebasi (Fåhraeus, 1839), S. leucostauros Johnson & Kingsolver, 1973, S. lojaensis (Pic, 1933), S. medialis (Sharp, 1885), S. nappi Ribeiro-Costa & Reynaud, 1998, S. rufomaculatus (Motschulsky, 1874), S. transversesignatus (Fåhraeus, 1839), S. trinotaticollis (Pic, 1930), S. vivi sp. nov. and S. flinte sp. nov. The S. abbreviatus group differs from other groups by the pattern of sclerites and the shape of the internal sac of the male genitalia, and has three subgroups, defined here. The lectotype of S. lebasi is designated. New host plant records are presented for S. lojaensis and S. transversesignatus, and new distribution records for S. lawrencei, S. lojaensis and S. trinotaticollis.

“…The American genus Merobruchus Bridwell has been included in a group of genera Merobruchus in the tribe Bruchini Pic, the largest tribe of Bruchinae Latreille. This group is composed of Caryedes Hummel, Ctenocolum Kingsolver & Whitehead, Gibbobruchus Pic, Meibomeus Bridwell, Merobruchus, Penthobruchus Kingsolver and Pygiopachymerus Pic (Whitehead and Kingsolver 1975;Silva 2005).…”

Gibbobruchus Pic, 1913 belongs to the subtribe Acanthoscelidina, which encompasses ~50% of the subfamily Bruchinae (Coleoptera : Chrysomelidae). These species are distributed in the Americas and are mainly associated with Bauhinia seeds (Fabaceae). The monophyly of Gibbobruchus and its species groups were tested based on 26 adult morphological characters and 15 taxa. Of these taxa, 13 species were recognised including two new species, G. vinicius, sp. nov. and G. bolivianus, sp. nov. Gibbobruchus is monophyletic and supported by seven synapomorphies. The currently proposed composition of species groups is: Group speculifer: G. speculifer, G. ornatus, G. vinicius, Manfio & Ribeiro-Costa, sp. nov.; Group polycoccus: G. polycoccus; Group wunderlini: G. wunderlini; Group scurra: G. cavillator, G. bolivianus, Manfio & Ribeiro-Costa, sp. nov., G. scurra; and Group mimus: G. guanacaste, G. iturbidensis, G. mimus, G. cristicollis, G. divaricatae. A lectotype is designated for G. triangularis and a neotype for G. mimus; two new synonyms are proposed: Gibbobruchus cavillator (Fåhraeus, 1839) = Gibbobruchus triangularis (Pic, 1926) syn. nov. = Gibbobruchus nigronotatus (Pic, 1931) syn. nov. Four species have new distribution records. An identification key for the species, descriptions, redescriptions, and illustrations, are also provided.
