Figs 1C, G , 10 A–D

Diagnosis

Genitalic structures characteristic of G. orautahi sp. nov. are the gonostylus, which is massive apically and strongly bent at the midlength (↓ 1, Fig. 10C ); the tegminal processes, which consist of a strongly sclerotized, tuberculous portion posteriorly and a weakly sclerotized, spiny portion laterally (↓ 2, Fig. 10D ); and the posteromedial protuberance, whose pointed, sclerotized process projects ventrally (↓ 3, Fig. 10B ).

Etymology

The specific epithet, orautahi , is the Maori name for Smoky Beach, the place on Stewart Island where the holotype was collected.

Other characters

BODY SIZE. 1.7 mm.

HEAD. Eye bridge 1–2 ommatidia long dorsally. Flagellomeres 15; neck of fourth flagellomere 1.5 times the node ( Fig. 1G ). Palpus slightly longer than head height, 4 setae-bearing segments, apical segment longest of all ( Fig. 1C ).

THORAX. Pronotal setae present.

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

LEGS. Basitarsal spines absent.

TERMINALIA. Posterior portion of ninth tergite strongly narrowed, covered densely with microtrichia, about 14 megatrichia on posterior edge (↓ 4, Fig. 10A ). Gonocoxites with separate, narrow, unsetose portion ventrobasally; ventroposterior lobes large, subtriangular; a group of 4–5 dense setae and an inconspicuous double lobe at base of ventral emargination ( Fig. 10B ). Gonostylus 2.5 times longer than broad, markedly wedge-shaped apically ( Fig. 10C ). Apex of ejaculatory apodeme membranous, arrowshaped ( Fig. 10B ).

Distribution and phenology
