Diagnosis

Glemparon rotoroa sp. nov. is an absolutely distinctive species, with the following genitalic characters. The gonocoxites have a pair of conspicuously large lobes ventroposteriorly, from which the strongly sclerotized margins of the ventral emargination set out (↓ 1, Fig. 15A). Close to the base of the emargination, on a slight ridge, is a dense group of about 20 setulae (↓ 2, Fig. 15A); other ventral setae are very sparse. The elongate gonostylus with hook-shaped apex is directed posteriorly rather than medially (↓ 3, Fig. 15A). The posterior portion of the ninth tergite, which is much narrower than the anterior portion, has about 15 marginal megatrichia (↓ 4, Fig. 15B).

Etymology

The specific epithet refers to Lake Rotoroa in the north of New Zealand’s South Island, where the holotype was collected.

Material examined

HEAD. Eye bridge 1–2 ommatidia long dorsally. Flagellomeres 12; fourth flagellomere with neck and node equally long. Palpus as long as head height, 4 setae-bearing segments; apical segment longest of all.

THORAX. Pronotal setae present.
