An illustrated key to the genera of Thripinae (Thysanoptera, Thripidae) from Iran Author Mirab-balou, Majid Author Minaei, Kambiz Author Chen, Xue-Xin text ZooKeys 2013 317 27 52 http://dx.doi.org/10.3897/zookeys.317.5447 journal article http://dx.doi.org/10.3897/zookeys.317.5447 1313-2970-317-27 Sitothrips Priesner Remarks. This genus includes four species ( ThripsWiki 2013 ) of which Sitothrips arabicus Priesner has been recorded from Iran ( Bhatti et al. 2009a , Mirab-balou and Chen 2011a ). This genus is included in the Frankliniella genus-group ( Mound and Palmer 1981a ). It is distinguished from other members of this group by lack of long setae on the anterior margin of the pronotum, the meso- and metathoracic furcae both without a spinula, the maxillary palps 2-segmented, and the fore tarsi with two small teeth (one at the apex of the tarsus, the other at the end of the first segment) ( Mirab-balou and Chen 2011a ). A key to three species of Sitothrips is available in zur Strassen (2003a) . In some parts of Iran, like as Golestan province, Sitothrips arabicus is largely present on wheat and barley ( Alavi et al. 2007 )
