Diagnosis

Glemparon pureora sp. nov. is distinguished from congeneric species by the compact gonostylus, which is strongly tapered towards the apex (↓ 1, Fig. 12A ); the broadly V-shaped gonocoxal emargination ( Fig. 12A ); the posteromedial protuberance, which has a three-branched sclerotization, with the medial branch forming a ventrally directed process (↓ 2, Fig. 12A ); and the tegmen, which ends in a pair of serrate processes that point ventrolaterally, and whose posterolateral processes are three-pointed (↓ 3, Fig. 12B ).

Etymology

The specific epithet, pureora , refers to the type locality of this species, Pureora Forest Park in the North Island of New Zealand, which protects one of the earth’s finest podocarp forests.

Material examined

Holotype

NEW ZEALAND: ♂, North Island , Taupo , Pureora Forest Park , Waipapa Ecological Area, 570 m a.s.l., “in shrubland”, 2 Feb. 1984, Malaise trap, J. Hutcheson leg. ( NZAC, no. CEC1424).

Other characters

BODY SIZE. 2.0 mm.

HEAD. Eye bridge 2–3 ommatidia long dorsally. Eleven flagellomeres retained; neck of fourth flagellomere 0.9 times the node. Two palpus segments retained.

THORAX. Pronotal setae present.

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

LEGS. Basitarsal spines absent.

TERMINALIA. Posterior edge of ninth tergite truncate, covered with partially coarse microtrichia ( Fig. 12A ). Gonocoxites with unsetose portion ventrobasally; ventroposterior lobes inconspicuous ( Fig. 12A ). Gonostylus twice longer than broad ( Fig. 12A ). Ejaculatory apodeme thin, with small, sclerotized broadening apically ( Fig. 12B ).

Distribution and phenology

The only specimen known of G. pureora sp. nov. was collected in summer, in shrubland embedded in an extensive podocarp forest in New Zealand’s North Island. Another species of Glemparon , G. waipapa sp. nov., was captured one month later at the same site, perhaps even with the same Malaise trap.
