Figs 1B , 20 A–D

Diagnosis

The tegmen consists of a massive, subtrapezoid portion basally and a biramous portion apically, both separated by a constriction; the rami end in leaf-shaped processes whose bases are covered with numerous tiny spikes (↓ 1, Fig. 20C ). The arrow-shaped apex of the ejaculatory apodeme is sclerotized (↓ 2, Fig. 20D ), not membranous as in most other species of Glemparon . The gonostylus is slightly broadened towards the apex (↓ 3, Fig. 20B ).

Etymology

The specific epithet, warra , refers to the type locality of this species. The Warra Long Term Ecological Research (LTER) site in southern Tasmania is a prime example of a temperate broadleaf (eucalypt) wet forest.

Material examined

Holotype

AUSTRALIA: ♂, Tasmania, Warra Long Term Ecological Research site, Mt. Weld , 43.07° S, 146.67° E, 100 m a.s.l., 27 Feb. 2001, eucalypt forest, Malaise trap, N. Doran & R. Bashford leg. ( AM, no. CEC1408).

Other characters

BODY SIZE. 1.9 mm.

HEAD. Eye bridge 0–1 ommatidium long dorsally. Fourteen flagellomeres retained; neck of fourth flagellomere 1.4 times longer than node. Palpus shorter than head height, 4 setae-bearing segments; apical segment longest of all.

THORAX. Pronotal setae absent.

WING. Length /width ratio 3.3. Rs short, one eighth of apicR 1.

LEGS. Basitarsal spines absent.

TERMINALIA. Posterior edge of ninth tergite broadly rounded to truncate (indicated in Fig. 20A ), with dense, large microtrichia. Gonocoxites ( Fig. 20A ): ventral emargination shaped like widely open U, flanked by small, subtriangular lobes; posteromedial protuberance partly slightly sclerotized; a separate, narrow, unsetose section ventrobasally. Gonostylus 2.5 times longer than broad; densely setose except the

concave portions medially and the angular-shaped, densely microtrichose apex ( Fig. 20B ). Ejaculatory apodeme conspicuously thick ( Fig. 20A ).

Distribution and phenology

The only specimen known of G. warra sp. nov. was Malaise trapped at the end of summer in the same habitat as the previous species.
