Related 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 generic relationships, because many of the character states exhibited appear related to the grass-living habit, including the long ovipositor, weakly developed wings, and elongate head.

Biological data

This species feeds and breeds on the leaves of Gahnia spp. (Cyperaceae).
