Hoplandrothrips Hood

About 110 species worldwide are listed in this genus, with four recorded from Australia ( Fig. 48 ), H. flavipes , H. fuscus , H. quadriconus and H. xanthocnemis , but several new species will be published in a manuscript due to go to press this year. These thrips live on dead branches, the adults are usually fully winged, there is considerable sexual dimorphism in some species, and males of some species vary greatly in size and armature that suggest some form of male/male competitive behaviour.

Diagnosis. Often sexually dimorphic, with males varying in body size; head shape variable, usually longer than wide, constricted behind eyes, reticulate dorsally; 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 2–4 (usually 3) sensoria, IV with 4; pronotum usually with 5 pairs of major setae, major males with anteroangular pair unusually long; notopleural sutures complete; basantra absent; mesopraesternum 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.
