pea and bean weevils

Mimosestes is a of in the , Bruchinae, containing approximately 13 described . These are associated with legume seeds and have been documented as species in some regions, including Hawaii. The genus has been subject to phylogenetic studies examining utilization patterns. Some species serve as hosts for , including the Urosigalphus mimosestes.

Distribution

distribution includes the Americas; at least one , Mimosestes sallaei, has been established as an species in Hawaii. GBIF records indicate presence in Colombia (CO), Norway (NO), and Sweden (SE), though the Norwegian and Swedish records likely represent introduced or intercepted specimens given the tropical to subtropical native range of Bruchinae.
