Rhaebus (from the Greek: ῥαιβός curved) is a genus of metallic bean weevils in the subfamily Bruchinae, and the only member of the tribe Rhaebini.[2][3][4] It is restricted to the Palearctic region.[4]

Appearance

Rhaebus beetles are small, measuring between 3-5 millimetres in length, and are metallic in colour, which is rare in members if the Bruchinae subfamily. Their bodies are elongated in shape, and the antennae vary.[5]

Diet and life cycle

Rhaebus beetles feed exclusively on plants of the genus Nitraria, where their young also develop.[5][6][7]

Taxonomic history

The genus was first described in 1824 by Gotthelf Fischer von Waldheim in his book Entomographie de la Russie.[8] He described it with only one species, Rh. gebleri, making the genus monotypic.[5]
