Phylladothrips Priesner

( Figs 68 , 131 )

Phylladothrips Priesner, 1933b: 79 . Type species: Phylladothrips karnyi Priesner , by monotypy.

All nine species listed in this genus are from Southeast Asia, with two from Taiwan, two from the Philippines, one from Malaysia, and four from Indonesia ( Okajima 1988b). These species are collected from dead leaves and branches where, presumably, they are fungus feeders. They are particularly unusual in having sigmoid wingretaining setae on the eighth tergite ( Fig. 68 ).

Diagnosis: Head a little longer than wide ( Fig. 131 ); eyes normal, postocular setae well-developed; stylets usually retracted to postocular setae, about one third of head width apart medially; antennae 8-segmented, III with 3 sensoria, IV with 4; pronotum with 4 pairs of developed setae, am reduced, notopleural sutures incomplete; basantra present but weak; mesopresternum transverse; sternopleural sutures absent; fore tarsal tooth absent on both sexes; fore wings weakly constricted medially, without duplicated cilia; pelta hat-shaped; tergites II–VIII with 2 pairs of wing-retaining setae ( Fig. 68 ); tube shorter than head; male sternite VIII without pore plate.
