Abstract

Gibbobruchus bergamini Manfio & Ribeiro-Costa sp. nov. (Coleoptera, Chrysomelidae, Bruchinae) is described from Brazil (state of Goiás) and it is here included in an updated key to the Gibbobruchus Pic species. The dorsal aspect, male and female pygidium and male genitalia are illustrated. This new species develops in seeds of 6 Bauhinia L. (Fabales: Fabaceae: Caesalpinioideae) species. New host plant records for other 4 species of Gibbobruchus are presented. Considering the host plants of G. bergamini sp. nov., a total of eleven new hosts are added to the genus; with exception of Phanera Lour. (Fabales:Fabaceae), which we recorded the first time for Gibbobruchus, all Gibbobruchus spp. were collected in Bauhinia seeds. Geographic distribution data and further comments on host plant associations are also included.

 

Gibbobruchus bergamini Manfio & Ribeiro-Costa sp. nov. (Coleoptera, Chrysomelidae, Bruchinae) se describe para Brasil (Estado de Goiás) y se la incluye en una clave actualizada de las especies de Gibbobruchus Pic. Se encuentran ilustrados el aspecto dorsal, pigidio del macho y hembra y la genitalia masculina. Esta nueva especie se desarrolla en las semillas de seis especies de Bauhinia L. (Fabales: Fabaceae: Caesalpinioideae). Se presentan nuevos registros de plantas hospederas para otras cuatro especies de Gibbobruchus. Incluyendo las plantas hospederas de G. bergamini sp. nov. un total de once nuevos hospederos se añaden al género; con excepción de Phanera Lour, por primera vez registrado en Gibbobruchus, todos ellos fueron recolectados en las semillas de Bauhinia. También se incluyen datos de distribución geográfica y comentarios sobre asociaciones con las plantas.
