Recognition data

Distinguishing features

Macropterous, strongly bicoloured; head brown with postoccipital region and anterior half of pronotum yellow; pronotal blotch and pteronota, also meso and metasternum, dark brown; abdominal segment I yellow with antecostal ridge interrupted medially, IIVI yellow scarcely shaded anterolaterally, antecostal ridge slightly darker, VIIX dark brown; legs mainly brown, hind tibiae variably yellow to brown, all tarsi yellow; forewings with pale sub-basal area before light brown band but uniformly pale in distal half. Head with occipital carina close to eyes; ocellar triangle transversely striate with markings in between the striae; ocellar setae III within anterior margins of triangle; three pairs of postocular setae, median pair long; postoccipital region transversely striate; mouth cone unusually long, extending to mesosternum. Pronotum anterior third transversely reticulate with few internal markings; blotch transversely striate with many markings between the major lines; posterior margin of blotch deeply concave, posteromedian discal setae arise behind the dark area. Mesonotum and metanotum with many small linear markings between the major sculpture lines, metanotal reticulation irregular but mainly linear. Metasternal anterior margin with shallow emargination. Forewing with no setae on second vein; wing apex with long sub-apical lobe. Tergites IVI medially without marginal microtrichia; IVV with few discal microtrichia medially. Sternites IIVII medially without marginal microtrichia, discal microtrichia not extending to setae S2. Male similar to female, sternites VVII with broadly transverse pore plate.

Related and similar species

Among the nine Neohydatothrips known from Australia, this species appears to one of a group that is associated with the leaves of native Fabaceae, and in which the forewing bears a sub-apical lobe. It is particularly close to N. haydni , but is distinguished particularly by the shape of the pronotal blotch.

Distribution data

Northern Australia, between Katherine (Northern Territory) and Kununurra (Western Australia).
