(type species: Hysteropterum bistriatum Caldwell 1945),. The genus Tylanira Ball 1936 is redescribed. The male genitalia of Tylanira bifurca Ball 1936 is described and illustrated. Tylana ustulata Uhler 1876 is transfered to Tylanira. Hysteropterum bufo Van Duzee 1923 is transfered to Balduza gen. n. and the male genitalia of the species is described and illustrated. The subgenus Paralixes Caldwell 1945 of the genus Ulixes St�l 1861 is raised to genus Paralixes Caldwell 1945, stat. n. A key to the issid genera of the United States is given.
