Additional description. Male. Head. Eye bridge 2 facets wide; frons between eye bridge and scape with a few bristles. Antenna short; 4th flagellomere with l/w-index of 1.4, with hairs pale, bristle-like and nearly as long as the width of the basal node; necks rather short, brownish; palpus 3-segmented; basal segment without sensory pit, with 4-5 bristles. Thorax. Scutum with rather short and brown central as well as lateral bristles; scutellum with 2 long and 4 shorter marginal bristles; postpronotum bare. Wing brownish; R1 = 1/2 R; R5 throughout with macrotrichia dorsally and ventrally; C = 3/4 w; y = x, with 1‒2 macrotrichia; M-fork long, posterior veins without macrotrichia. Haltere short, brownish. Legs brownish; tibial organ small, with 4‒5 fine hyaline bristles in an irregular row; spurs of middle and hind tibia equal in size, longer than the width of apex of tibia; claws missing. Abdomen. With rather long, dense brownish hair. Hypopygium with broad open ventral base, without lobe or patch of bristles; gonocoxite with short and sparse hairs on the inner ventral margin; gonostylus curved in the apical third, densely hairy on the apex, with 2 subapical spines as long as apical hairs, and with a long whiplash hair below; tegmen wider than long, with dark sclerotized shoulders laterally, rounded apically; aedeagus rather short, with large furca.

Comments. This species is characterized by very short flagellomeres, frons with short bristles, gonostylus with 2 short spines and a much longer whiplash hair, and a tegmen that has rather strongly sclerotized shoulders. The type specimens of S. familiaris and S. festiva are in rather good condition. Both are identical to Psl. cavatica (Skuse 1888) in all details.
Distribution. Australia (New South Wales).
