Metanotum irregularly reticulate, median setae arise behind anterior margin; campaniform sensilla absent. Prosternal ferna complete medially, with anterior extension bearing 2 pairs of setae; meso- and metafurca without spinula. Fore wing first vein with 1–3 setae on distal half, second vein with 4 setae; clavus with 2–4 veinal setae but no discal seta.

Related and similar species

The genus Karphothrips includes only a single species. Although described originally from New Zealand, this species is an Australian endemic that is widespread across the south of the continent. At present it is not possible to suggest any relationships, because many of the character states exhibited appear related to the grass-living habit, including the long ovipositor, reduced wings, and elongate head.
