Genus Acetropis Fieber, 1858

Acetropis Fieber, 1858:302; Kerzhner, 1964:47 (key); Štys, 1973:9 (key); Wagner, 1974:100 (key, descriptions); Schwartz, 2008:1175 (diagnosis).

Diagnosis. Males macropterous; females submacropterous (hemelytra usually reduced to various extent). Body covered with sparse, fine and adpressed silvery setae; head porrect; vertex usually without longitudinal sulcus; frons usually conical and projecting to the anterior margin of clypeus; lateral margins of pronotum curved upwards, pronotum with laminate, strongly explanate lateral margins, sometimes with distinct longitudinal carina along midline; left paramere sickle-shaped; right paramere club-shaped, medially constricted; vesica with two or three long basal processes; female genitalia with narrow interramal sclerite (Schwartz, 2008).

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.
