Fig. 4 A–C

Diagnosis

A peculiarity of G. aotearoa sp. nov. is the markedly bulbous gonostylus (↓ 1, Fig. 4B ). Of the gonocoxites, the membranous areas below the gonostyli are conspicuously large (↓ 2, Fig. 4A ), the small, subrectangular, ventral emargination (↓ 3, Fig. 4A ) is flanked by subtriangular lobes of moderate size, and the posteromedial protuberance is inconspicuous. The posterolateral processes of the tegmen have serrate edges, including one larger, bent sawtooth anteriorly (↓ 4, Fig. 4C ).

Etymology

The specific epithet, aotearoa , is the Maori name for the country of New Zealand, meaning “land of the long white cloud”.

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. CEC1419).

Other characters

BODY SIZE. 2.0 mm.

HEAD. Eye bridge 2 ommatidia long dorsally. Flagellomeres 15; apical flagellomere obviously merged of two bodies; neck of fourth flagellomere 1.1 times the node. Palpus shorter than head height, 4 setaebearing segments.

THORAX. Pronotal setae present.

WING. Length / width ratio 3.1. Rs short, one fifth of apicR 1.

LEGS. Basitarsal spines present.

TERMINALIA. Posterior edge of ninth tergite with large, hair-like microtrichia. Gonocoxites with narrow, unsetose, separate section ventrobasally ( Fig. 4 A ). Gonostylus twice longer than broad; outside densely setose; inside with dense, fine pubescence, and very few fine setulae ( Fig. 4 B ). Apex of ejaculatory apodeme small, membranous, arrow-shaped ( Fig. 4 C ).

Distribution and phenology

The single specimen known of G. aotearoa sp. nov. was Malaise trapped at the height of summer in an old-growth native forest in the north of New Zealand’s South Island. The same trap collected simultaneously four other species of Glemparon : G. birhojohmi sp. nov., G. cervus sp. nov., G. rotoroa sp. nov., and G. tewaipounamu sp. nov.
