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
[edit | edit source]Rhaebus beetles are small, measuring between 3–5 millimetres in length, and are metallic in colour, which is rare in members of the Bruchinae subfamily. Their bodies are elongated in shape, and the antennae vary.[5]
Diet and life cycle
[edit | edit source]Rhaebus beetles feed exclusively on plants of the genus Nitraria, where their young also develop.[5][6][7]
Taxonomic history
[edit | edit source]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]
