The genus Acetropis Fieber, 1858 currently contains seven species subdivided into two subgenera based on the structure of the head and the first antennomere ( Wagner, 1967; Štys, 1973). The subgenus Acetropis consists of A. carinata ( Herrich-Schaeffer, 1841) , A. americana Knight, 1927 , A. gimmerthali (Flor, 1860) , A. longirostris Puton, 1875 , A. sinuata Wagner, 1951 , A. stysi Remane & Günther, 2008 , and A. sinuata Wagner, 1951 . The subgenus Paracetropis Wagner, 1962 is monotypic, containing A. atropis Reuter, 1895 . Of these, six species are represented in the western Palearctic region, while A. americana is found exclusively in western Oregon, North America ( Knight, 1927; Slater & Baranowski, 1978). This genus occurs on grasses ( Poaceae ), although few specific host plants have been identified ( Southwood & Leston, 1959; Koppanyi, 1965). In this paper, Acetropis is reported for the first time from Iran.
