( Fig. 123 )

Cephalothrips Uzel, 1895: 244 . Type species: Phloeothrips monilicornis Reuter , by monotypy.

Although eight species are listed in this genus, it remains uncertain if they are all closely related. No species is known from SE Asia, but the common European species, monilicornis (Reuter) , is recorded from Inner Mongolia, and one species has been described from southern China, Sichuan ( Han et al. 1991; Cao & Feng 2011).

Diagnosis: Usually apterous; head longer than wide ( Fig. 123 ); eyes prolonged ventrally, postocular setae scarcely reaching posterior margin of eyes; stylets retracted nearly to eyes, about one fifth of head width apart; antennae 8-segmented, VII and VIII broad at base, III with 1 sensorium, IV with 2; pronotum with epim and sometimes pa setae about as long as width of antennal II, am, aa and ml minute, notopleural sutures complete ( Fig. 123 ); basantra absent; mesopresternum reduced to lateral triangles; sternopleural sutures present; fore tarsi with small tooth; macroptera with fore wings lacking duplicated cilia; pelta broad; tergites II–VII without sigmoid wingretaining setae; tergite IX setae S1 and S2 shorter than basal width of tube; tube shorter than head, anal setae shorter than tube.
