Apterygothrips Priesner

( Fig. 23 )

Apterygothrips Priesner, 1933a: 1 . Type species: Apterygothrips haloxyli Priesner , by monotypy.

There are 40 species included in this genus, of which three are recorded from China, one from the northern Palaearctic area, and two from the South or Southwest. This genus, a member of the Haplothripini , is possibly polyphyletic because it is defined from Haplothrips only on the basis of lack of wings and tergal wing-retaining setae.

Diagnosis: Head longer than wide; eyes normal, or slightly prolonged ventrally, postocular setae welldeveloped; stylets retracted to just behind eyes, about one third of head width apart, maxillary bridge present; antennae 8-segmented, III with 1 or 2 sensoria, IV with 2 or 3; pronotum usually with 5 pairs of developed setae, notopleural sutures complete; basantra present; mesopresternum transverse or eroded medially; sternopleural sutures usually absent, sometimes present ( Fig. 23 ); fore tarsal tooth present or absent; commonly micropterous, macropterae with fore wings weakly constricted medially, without duplicated cilia; pelta trapezoidal or hemicircular; tergites II–VII with 2 pairs of wing-retaining setae in macroptera; tube shorter than head.
