Holothrips Karny

Almost 130 species are listed in this genus, and Okajima (1987) provided a key to 69 species from the Old World. Three species are described from Australia, H. australis , H. oceanicus and H. speciossissimus , but several undescribed species are represented in ANIC that have been taken widely between Tasmania and northern Queensland. The maxillary stylets are distinctly wider than those of typical Phlaeothripinae (Fig. 25), but rarely as broad as the stylets of Idolothripinae .

Diagnosis. Head usually longer than wide; postocular setae usually developed; stylet width unusually broad, stylets usually retracted to eyes, close medially; antennae 7-segmented, segments VII and VIII more or less fused, III with 3 sensoria, IV with 4; pronotum usually with 5 pairs of major setae, notopleural sutures usually complete; basantra absent; mesopraesternum transverse; sternopleural sutures present; fore tarsal tooth present in both sexes; fore wings parallel-sided, with duplicated cilia; pelta bell-shaped or triangular; tergites II–VII with wing-retaining setae variable; tube variable in shape, anal setae usually shorter than tube; male sternites IV–VII usually with transverse reticulated areas.
