Hoplandrothrips

Head variable in length, usually 1.0–1.5 times as long as wide, dorsal surface usually reticulate, sometimes smooth or weakly sculptured; often constricted behind eyes. A pair of postocular setae developed, usually situated near cheeks, distance between them more than 1/2 head width. Antennal segment IV with four sense cones (2+2). Maxillary stylets usually close together, sometimes narrowly separated, usually narrower than 1/5 head width; long, variable in length, usually reaching postocular setae or longer. Pronotum usually with 5 pairs of major setae; major males commonly with anteroangular pair particularly long; notopleural sutures complete. Fore femur enlarged, with an inner apical tubercle (often a pair in males); fore tibia with an inner sub-basal tubercle in large males, usually placed basal 1/3–2/5; fore tarsal tooth present in both sexes. Wings weakly constricted medially to parallel-sided. Abdominal tergites II–VII each with two pairs of wing-retaining setae; tergite IX often with a pair of long intermediate setae between S1 and S2. Tube shorter than head; anal setae usually as long as tube or longer. Often sexually dimorphic, with males varying in body size.
