Diagnosis

Glemparon rakiura sp. nov. is distinguished by the gonocoxal ventroposterior lobes, which are conspicuous by their globular shape and dense cover with thick, spine-like microtrichia dorsomedially (↓ 1, Fig. 13A View Fig ). The gonostylus, which basically is rather slender, has a densely microtrichose protuberance dorsobasally (↓ 2, Fig. 13A View Fig ). The ninth tergite has a narrow posterior portion, which is separated from the much broader anterior portion by a constriction and is covered with microtrichia of various sizes; the posterior edge is provided with about 10 megatrichia (↓ 3, Fig. 13B View Fig ).

Etymology

The specific epithet, rakiura , is the Maori name for Stewart Island, the provenance of the holotype specimen.
