Heliothripoides Okajima

( Figs 15 , 45–48 )

Heliothripoides Okajima, 1987c: 294 . Type species: Heliothripoides reticulatus Okajima , by monotypy.

This genus is presumably a member of the Phlaeothrips -lineage of fungus-feeding species. The type species was described from Borneo, but a second species of the genus from that island is described below.

Diagnosis: Body polygonally sculptured ( Figs 46, 47 ); head about as long as wide, swollen just behind eyes ( Fig. 46 ); eyes sometimes prolonged ventrally, postocular setae minute; stylets retracted to one third of head length, close together medially; antennae 8-segmented ( Fig. 15 ), III with 2 sensoria, IV with 2 or 3; pronotum with epim setae developed, other major setae usually small, notopleural sutures complete; basantra absent; mesopresternum transverse; sternopleural sutures absent; fore tarsal tooth absent in both sexes; fore wings weakly constricted medially, without duplicated cilia; pelta trapezoidal; tergites II–VII with 2 pairs of flattened wing-retaining setae; tergite IX with setae S1 and S2 short ( Fig. 45 ); tube with straight sides, shorter than head; male sternite VIII without pore plate.
