The genus Diaspidistis Hempel, 1900 was studied. Diaspidistis multilobis Hempel, 1900 and D. squamosa Hempel, 1937 were redescribed. New combinations are proposed: D. gomescostai (Lepage & Giannotti, 1946), D. memorabilis (Ferris, 1941), D. multipunctata (Lepage & Giannotti, 1946) and D. petasata (Ferris, 1942). Two new species are described and illustrated: Diaspidistis fonsecai sp. nov. and Diaspidistis tucumanensis sp. nov. A key to the species is presented based on adult females.
