Hoplandrothrips Hood

( Figs 63, 64 )

Phloeothrips (Hoplandrothrips) Hood, 1912: 145 . Type species: Phloeothrips (Hoplandrothrips) xanthopus Hood , by original designation.

This genus of polymorphic, fungus-feeding species is recorded world-wide. It includes 117 species, and although eight are listed from China, there are few known from other parts of Southeast Asia, although Mound and Tree (2013) recorded 16 species from Australia. These thrips live mainly on dead branches, sometimes forming large colonies that exhibit sexual dimorphism as well as male polymorphism.

Diagnosis: Often sexually dimorphic, with males varying in body size ( Figs 63, 64 ); head shape variable, usually longer than wide, constricted behind eyes, reticulate dorsally ( Fig. 64 ); postocular setae usually well developed, wide apart; stylets usually retracted to eyes and close together medially, rarely short and wider apart; mouth cone variable; antennae 8-segmented, III with 3 (or 2–4) sensoria, IV with 4; pronotum usually with 5 pairs of major setae, major males with aa setae unusually long, notopleural sutures complete; basantra absent; mesopresternum transverse, or divided into three plates; sternopleural sutures present; fore tarsal tooth present in both sexes, male fore femur often with pair of apical tubercles; fore wings usually weakly constricted medially, with duplicated cilia; pelta bell-shaped; tergites II–VII each with 2 pairs of wing-retaining setae; tube shorter than head, anal setae usually as long as tube or longer; male sternite VIII with or without pore plate.
