( Fig. 20 A–D View FIGURE 20 )

Type locality: Australia, New South Wales, Minnamurra Falls .

Holotype: Male, 28.v.1963, leg. D.H. Colless, ASCT 00049063 ( ASCU).

Paratypes: 4 males, 1 female, same locality , same data ( ASCT00054347 , ASCT00049062 in PWMP; ASCT00049064 in ANIC; ASCT00049065 in PABM) .

Description. Male. Head. Brown. Eye bridge 3–4 facets wide. Flagellomeres with rough surface; scape, pedicel and first flagellomere yellowish, the others brown; 4th flagellomere with l/w index of 2.5, hairs as long as the diameter of the basal node; neck rather long, bicoloured. Palpus pale, 3-segmented, basal segment with 7–8 bristles without a deepened sensory area, 3rd segment long. Thorax. Yellow. Scutum with three darker stripes, scutellum without distinct marginal bristles; pleural sclerites with a few indistinct darker patches. Wing brownish, R1 = 3/4 R; R 5 in distal half with ventral macrotrichia; C nearly 1/2 w; y long, = 3 x, with few macrotrichia; posterior wing veins with macrotrichia. Haltere brownish. Coxae and femora yellow, tibiae and tarsi brownish; apex of fore tibia with a wide comb of bristles; spurs of middle and hind tibia equal in size, longer than the diameter of the apex; claws with strong teeth. Abdomen. Brownish, with rather dense hairs. Hypopygium with bare intergonocoxal space; gonocoxites at the inner ventral margin with rather long hairs, with 1 macroseta on the ventral apex; gonostylus prolonged, the apex with short and dense hairs, the inner side somewhat bulbous, with 6–8 long bristlelike spines. Tegmen large, longer than wide, rounded apically, with fine teeth. Aedeagus short. Body length: 5.0 mm.

Comments. The species is characterized by the yellow body colour, claws with strong teeth, one macroseta on the ventral apex of the gonocoxites and a bare intergonocoxal space. It differs from the other Australian species by having only one macroseta and the ventral base of the hypopygium is without a lobe or bristles.

Distribution. Australia: New South Wales.
