The first record of grass-living thrips, Chirothrips hamatus (Thysanoptera: Thripidae) in Iran

Species of the genus <em>Chirothrips</em> Haliday live on various species of grasses (family Poaceae). In this research, <em>Chirothrips</em> <em>hamatus</em> Trybom is reported for the first time in Iran as the seventh species recorded in this country for the genus so far. Most specimens of <em>C. hamatus</em> were collected on <em>Phragmites</em> sp. in Khuzestan Province (Iran). As for <em>Chirothrips</em> <em>atricorpus</em> Girault that has been previously reported in Iran, the second antennal segment in<em> C. hamatus</em> is symmetrical. The morphological differences of these two species are discussed and illustrated herein
