چکیده
REPRESENTATIVES OF THE SUBFAMILY BRUCHINAE (COLEOPTERA Chrysomelidae) are usually small and inconspicuous, with only a few species drawing the attention. Here we deal with several unusually colored species of Amblycerus Thunberg, 1815, one of the two most diverse bruchine genera in the Western hemisphere. We define the virens group that consists of five species whose bodies are covered with a green vestiture, including one new for science, Amblycerus medialis Ribeiro-Costa, Vieira & Manfio, sp. n. (Type locality: Brazil: Pará, Rondônia). This study also provides redescriptions, diagnoses, comparative notes, illustrations, geographic distribution records and a key to the species in this group.

Taxonomy, host-plant associations and phylogeny of African Crotalaria-feeding seed beetles (Coleoptera, Chrysomelidae, Bruchinae): the Conicobruchus strangulatus (Fåhraeus) species group.
A small group of six morphologically related seed beetles (Coleoptera: Chrysomelidae: Bruchinae) belonging to the Conicobruchus genus is reviewed. Species in this group for which host-plants are known feed on various species of Crotalaria (Fabaceae, Crotalarieae). Here we provide diagnoses and a dichotomous key for all six species. The following synonymies are proposed: Conicobruchus cicatricos...

Nineteen species of seed-beetles belonging to the subfamily Bruchinae (Coleoptera, Chrysomelidae) were collected in Xinjiang, China. Of these, the following four were new records for China: Bruchusaffinis Frolich, 1799, Bruchusatomarius L., 1761, Bruchusloti Paykull, 1800 and Kytorhinuskergoati Delobel & Legalov, 2009. We provide an annotated checklist, illustrations and a key to the 19 species.

Bruchidius Schilsky is a large paraphyletic genus of seed beetles (Coleoptera: Chrysomelidae: Bruchinae) which consists of multiple lineages that are usually associated with narrow sets of host-plants. In this study we focus on a group that mostly develops on wattle trees (acacias) belonging to the genus Vachellia Wight & Arn. This group originally included nine species and was designated as th...
