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

Holotype

NEW ZEALAND: ♂, South Island, Tasman, Nelson Lakes National Park, Lake Rotoroa , 450 m a.s.l., 15 Jan. 2001, mixed podocarp / southern beech forest, Malaise trap, Department of Conservation St. Arnaud leg. ( NZAC, no. CEC1415).

Paratypes

NEW ZEALAND: 2 ♂♂, same data as for holotype ( NZAC, nos CEC1416–CEC1417).

Other characters

BODY SIZE. 1.7 mm.

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.

WING. Length /width ratio 2.9. Rs short, one eighth of apicR 1.

LEGS. Basitarsal spines absent.

TERMINALIA. Gonocoxites: membranous areas below gonostyli large; dorsal apodemes closely adjacent to each other; posteromedial protuberance without obvious structuring ( Fig. 15A ). Gonostylus more than 3.0 times longer than broad; outside densely setose; inside with dense, fine pubescence, a very few fine setulae ( Fig. 15A ). Apex of ejaculatory apodeme unmodified ( Fig. 15C ). Apices of tegminal processes bent ventrolaterally, with several inconspicuous spikes; longitudinal apodemes unusually distinct ( Fig. 15C ).
