Tribe Litosomini Lacordaire

Aside from the genera Sitophilus and Cosmopolites , these are the most rarely encountered Dryophthoridae . There are seven genera and 12 species present, including one new genus and four new species to be described in a forthcoming paper (Anderson, in press). They are characterized by a normal articulation between the femur and tibia, and a rhomboidal scutellum with its greatest width near the middle. Very little is known of their natural history.
