Warramyia weldensis JASCHHOF sp. n.

( Figs 1 A-B, 2A-C)

Description:

Male. Body size: 0.8 mm. Head: Eye bridge 2 ommatidia long laterally and 3-4 ommatidia dorsally. 4 postocular bristles. Neck of fourth antennal flagellomere as long as node; node with 1 whorl of short setae subbasally, 1 complete and 1 incomplete whorl of long sensory hairs, several hair-shaped translucent sensilla distolaterally, on first to fifth flagellomeres 1 incomplete collar-shaped sensillum distomedially ( Fig. 2B ). First segment of maxillary palpus thickest of all segments, second segment almost globular, third and fourth segments short subcylindrical ( Fig. 2C ).

Thorax:

Fig. 1B . Scutum with sparse setae laterally and dorsocentrally. Wing: Fig. 1A . Narrow. Dorsal setae only on basR1, no ventral setae. Setae on membrane petering out towards wing base. Pattern of sensory buds: basR1, 1; apicR1, 2; Rs, 1; R5 basally, 1; R5 distally, 1. Costal cell extremely small. Costal break present. ApicR1 as long as Rs. M vestigial. CuA2 short and weak.

Preabdomen: Segment 1 and tergum 2 asetose. Terga 3-8 with few lateral and single dorsal setae.

Terga 6-8 sclerotized. Sterna 2-8 setose. Terminalia: Fig. 2A . Tg9 subtrapezoid, apparently asetose (not figured). Gonocoxites with a few short setae, ventroapical margin with wide emargination, a small bare membranous lobe medially. Gonostylus subcylindrical, with a few short setae and numerous large microtrichia, especially on apical half. Ejaculatory apodeme longer than gonocoxites and tegmen, strongly sclerotized, slightly widened towards apex. Tegmen large, longer than gonocoxites, slightly constricted medially, largely membranous, parameral apodemes sclerotized. Cerci with large microtrichia, no setae.

Etymology:

The name is derived from Mount Weld, the type-locality.

Types:

Holotype: Male, Australia, Tasmania, Warra LTER site, Mt Weld , 100 m a.s.l., 27 Feb. 2001, Malaise sample FT19, N. DORAN & R. BASHFORD (in AMS).
