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)
