(Fig. 124)

Psephenothrips Reyes, 1994: 478 . Type species: Psephenothrips strasseni Reyes, by monotypy.

Five species are listed in this Asian genus. One was described from Taiwan and one from the Philippines, but two come from central Japan and the fifth from southern India. These are leaf-feeding species, and the genus is distinguished from Liothrips by the longer maxillary stylets that are close together medially in the head (Fig. 124), and the absence of a pore plate on the eighth sternite of males.

Diagnosis: Head longer than width (Fig. 124); eyes normal, postocular setae well developed; stylets retracted to postocular setae, close together medially; antennae 8-segmented, III with 1 sensorium, IV with 3; pronotum with 5 pairs of developed setae, notopleural sutures complete; basantra absent; mesopresternum transverse; sternopleural sutures absent; fore tarsal tooth absent in both sexes; fore wings parallel-sided, with duplicated cilia; pelta triangular; tergites II–VII with 2 pairs of wing-retaining setae; tube with straight sides, shorter than head; male sternite VIII without pore plate.
