( Fig. 22 A–E )

Type locality: Australia, New South Wales, Condobolin.

Holotype: Male, 13.vii.1978, from soil, leg. A. Westcott, ASCT 00053674 ( ASCU).

Paratypes: 1 male, 13.vii.1978, Derriwong (near Condobolin), leg. B. Read, ASCT 00053800 ( PWMP); 1 male, 14.xii.1978, New South Wales, Jerilderie, caught by net, ASCT 00054274 ( PABM); 3 males, 20.iii.1981, Wingham Brush, Near Taree, leg. B.J. Loudon, ASCT 00054305 ( PABM) / ASCT 00054307 ( ASCU) / ASCT 00054303 ( PWMP); 1 male, 25.x.1979, New South Wales, Jerilderie, rotating trap, leg. unknown, ASCT 00053577 ( PWMP).

Description. Male. Head. Dark brown. Eye bridge 3 facets wide. Antenna brown; 4th flagellomere with l/w index of 2.2, hairs erect, as long as the diameter of the basal node; neck brown. Palpus brownish, 3-segmented, basal segment with 4–5 bristles, without a deepened sensory area. Thorax. Brown. Scutum with whitish hairs, some lateral and prescutellar bristles longer. Postpronotum bare. Wing brownish, R1 = 1/2 R; R5 without ventral macrotrichia; C = 2/3 w; y = x, without macrotrichia; posterior wing veins without macrotrichia. Haltere brownish. Coxae and legs brown; apex of fore tibia with a wide, slightly arched comb-like row of bristles; spurs of middle and hind tibia equal in size, slightly longer than the diameter of the apex; claws without teeth. Abdomen. Brown, with fine and sparse whitish hairs. Gonocoxites with dense hairs at the basal third of the inner ventral margin; gonostylus rather short and compact, the apex widely rounded, with short and dense hairs and a long subapical whiplash hair (distinct spines are not visible between the hairs). Tegmen deformed. Body length: 3.5 mm.

Comments. This large and dark species is characterized by the whitish body hair, dense hairs at the basal third of the ventral inner side of the gonocoxites, a strong gonostylus with dense hairs at the apex, a long subapical whiplash hair and no spines among the hairs at the apex. It is similar to Psl. capillosa Vilkamaa, Hippa & Mohrig. It differs by having longer flagellomeres, whitish body hairs, a shorter and more robust gonostylus, different shape of the tibial organ and a longer y.

Distribution. Australia: New South Wales.
