The genus Ischnopterapion is part of a group of apionid weevils characterized by their small size and elongated rostrum. The species was described by William Kirby in 1808 and occurs in Europe and parts of North America.
Tychius semisquamosus
Tychius semisquamosus is a species of leguminous seed weevil in the family Curculionidae, described by Faust in 1893. It belongs to the semisquamosus group of North American Tychius species, which are associated with host plants in the genus Astragalus and Lotus. The species has been subject to taxonomic revision, with several previously described species (T. lamellosus, T. squamosus, T. intermixtus) now synonymized under this name. It represents part of a North American fauna derived from multiple independent dispersals from Eurasia.
