INSECTA MUNDI, Vol. 9, No. 3-4, September - December, 1995 221 Review of the Nearctic species of AnaphothriPs (Thysanoptera: Thripidae) Sueo Nakahara Systematic Entomology Laboratory PSI, Agricultural Research Service, USD1!~ 10300 Baltimore Avenue Beltsville, Maryland 20705-2350 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.
