Chirothrips atricorpus Girault

Chirtothrips (sic) atricorpus Girault, 1927:1 .

Although this species was described originally from Australia, it is not considered to be native to that continent. Mound & Palmer (1972) suggested that it was probably introduced to Australia by shipping from one of the East African ports, and these authors also reported the species from Ethiopia. Bhatti et al. (2009) list it from Iran together with earlier references from that country.

Diagnosis: Body colour brown, tarsi light brown, forewing and clavus shaded. Head weakly produced in front of eyes ( Fig. 5 ); vertex with two pairs of setae, ocellar setae lateral to fore ocellus. Antennal segment II not produced on external margin; sensoria on segments III–IV simple and stout; antennal segment I without transverse ridge on dorsal surface. Tergal campaniform sensilla posterior to median setae; posterior margins of tergites I–VIII with broadly-based oval craspedate lobes that fuse at their bases to a continuous craspedum; sternites II–VI posterior margins with slender craspedate lobes, VII with lobes present only laterally. Male macropterous, craspedum on posterior tergites entire with small rounded lobes.
