(Fig. 13 A–B)

Type locality: Australia, Queensland, Mt Lewis, 37 km WSW of Port Douglas, 16°35´S, 145°16´E .

Holotype: Male, 29.vi.1997, rain forest, Malaise trap, leg. J. Seymour, in ANIC.

Description. Male. Head: Round, mouth parts not elongate; eye bridge 3 facets wide; antenna brown; 4 th flagellomere with a l/w index of 1.8, with a rather long neck, surface rough, sensilla inserted in deep pits, hairs bristle-like and shorter than the diameter of the basal node; palpus 3-segmented; basal segment with 2–3 bristles and a patch of short sensilla. Thorax: Brown; scutum with short dorsocentral and few stronger lateral hairs; scutellum with 2 longer marginal hairs; postpronotum bare. Wings brownish, with distinct veins; R 1 = 3/4 R; R 5 without ventral macrotrichia; C = 2/3 w; y = x, bare; Cu-stem short; posterior wing veins without macrotrichia. Haltere short, with darkened knob; legs yellowish; fore tibiae at the inner apex with a distinct row-like patch of bristles and a semicircular border; spurs of middle and hind tibiae of the same size, yellowish and somewhat longer than the diameter of the apex; claws finely toothed. Abdomen: Tergal and sternal hairs moderately long and sparse; hypopygium brown, ventral base v-shaped, the inner ventral margin of gonocoxites with short sparse hairs; gonostylus elongate, weakly curved, apically rounded, with only 1 short hyaline spine and a long whip-lash hair; tegmen wide, with an inner semicircular structure; aedeagus short and strong. Body length: 1.6 mm.

Comments. The species is characterized by having only one spine on the gonostylus, a wide tegmen with a semicircular structure and rather short flagellomeres with bristle-like hairs, shorter than the diameter of the basal node. It is similar to the Palaearctic species Psl. unispina (Mohrig & Krivosheina, 1983) and Psl. microcteniuni (Yang & Zhang, 1987) [after Menzel & Smith (2009)]. It differs from both species mainly by possessing a longer spine and a much longer whiplash-hair. It belongs to the Psl. bruckii group sensu Menzel & Mohrig (2000).

Distribution. Australia (Queensland).
