Hydatothrips argenticinctus Girault 1927: 1

This species is widespread in eastern Australia and has been taken at various sites between Batemans Bay and Brisbane. Two specimens have been studied from Weipa, Cape York Peninsula, that differ only in having the metanotal sculpture even more strongly linear. This thrips breeds on the leaves of P. straminea , a vine that is common in the eastern wet-sclerophyll forests.

Female macroptera. Body and legs strongly bicoloured, mainly brown with pronotum largely yellow but fore coxae brown; metathorax posterior half and abdominal tergite I yellow; tergites IV–VI yellow, sometimes with antecostal line dark in association with two small sub-median light brown areas; hind tibiae yellow in contrast to brown femora; forewings banded with pale sub-basal area and extensive sub-apical area paler than dark apex. Head with occipital carina close to eyes; ocellar triangle transversely striate; ocellar setae III arise outside ocellar triangle; three pairs of postocular setae, median pair long; postoccipital area transversely striate/reticulate. Pronotum with anterior third transversely reticulate, blotch transversely striate with markings between main striae. Metanotum with linear reticulation and linear markings within the reticles. Tergite I medially with no craspedum, II–IV with short microtrichiate craspedum medially, longer on V–VI. Sternites with no discal microtrichia medially, posterior margins with small lobed craspedum bearing long microtrichia between each pair of marginal setae; sternite VII medially with neither median discal nor marginal microtrichia.

Male. Sternites without glandular areas.
