Abstract: Seventeen species of Anaohothrips are here recorded and reviewed from the Nearctic Region. Six new species, A. heloolas, A. lateas, A. I1texicUitUS, A. paludicola, A. £1 i"tacalatus, and A. Ultioittatus, and 11 nOlninal species ale described. A key to the females of17 species and to males of 11 species is provided. Anaphothrips [lavocastaneus Johansen isreassigned to ()xythrlps, A rzplcola Hoodisrevivedasa good species, A sandPrsonl Stannard istreated asajunjor synonym ofA. decolor Hood, and A. sudanensis Trybom is reported from Mexico.
