Neohydatothrips poeta (Girault)

( Figs 70–72 )

Hydatothrips poeta Girault 1926: 1

Described from a single female specimen that is crushed and shattered into fragments, the identity of this species can be established from the reticulate sculpture of the metanotum, and the presence of a small microtrichiate craspedum on all but the first abdominal tergite. The generic placement of the species is more problematical, because the metasternum is more deeply emarginate than in any other Neohydatothrips species ( Fig. 71 ). Apart from the holotype, the only other known specimen is a female taken near Taree (NSW) from Eupomatia laurina (Eupomatiaceae) , a plant of the eastern rainforests.

Recognition: Body mainly dark brown, tergite V yellow laterally, pronotum with dark brown reticulation on anterior third; all tarsi yellow, mid and hind tibiae yellow at base and apex; forewings dark with pale subbasal area. Head with occipital carina close to eyes; ocellar triangle transversely reticulate; ocellar setae III lateral to triangle; two pairs of postocular setae, median pair not long and arising near posterior ocelli; postoccipital region reticulate. Pronotum anterior third boldly reticulate with faint dots internal to each reticle; blotch transversely reticulate with many dots internal to reticles, anterior angles of blotch acute. Metanotum with equiangular reticulation, with many internal dot-like markings; metasternal anterior margin with broadly Vshaped emargination. Forewing second vein with one seta; sub-apical lobe not developed. Tergite I medially without discal or marginal microtrichia, II–VI with short microtrichiate craspedum medially; antecostal ridge interrupted medially on tergite I, dark brown on II–VII. Sternites III–VII medially with neither discal microtrichia nor marginal microtrichia.
