Pseudolycoriella paucispinata sp. n.

( Fig. 9 A–D)

Type locality: Australia, Queensland, Black Mountain Road near Kuranda, 33 km WNW of Cairns.

Holotype: Male, 28.viii.1997, rain forest, Malaise trap, leg. J. Seymour, in ANIC.

Paratypes: 1 male, 8.viii.1997, locus typicus, in PWMP ; 2 males, 8.viii.1997, Mt Lewis , 37 km WSW of Port Douglas, 16°35´S, 145°16´E, rain forest, leg. J. Seymour, 1 in PABM , 1 in PWMP.

Description. Male. Head: Round, mouthparts not elongate; eye bridge 3 facets wide; antenna brown; 4 th flagellomere with a l/w index of 1.8, with a rather short neck, surface somewhat rough, some sensilla with deep pits, hairs dense and as long as half of the diameter of the basal node; palpus 3-segmented; basal segment with 2–4 bristles and a patch of short sensilla. Thorax: Brown; scutum with rather long dorsocentral and a few more robust lateral hairs; scutellum with 4 longer marginal hairs; postpronotum bare. Wing broad and pale, with distinct veins; R 1 = 2/3 R; R 5 without ventral macrotrichia; C = 2/3 w; y = x, bare; Cu-stem rather short; posterior wing veins without macrotrichia. Haltere short, with darkened knob; legs yellowish; fore tibiae at the inner apex with two distinct rowlike patches of bristles and a semicircular border; spurs of middle and hind tibiae of the same size, brownish and 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, apically rounded, with 2 short spines of the same size and a short whip-lash hair, shorter than spines; tegmen wide, apically rounded; aedeagus rather long and thin. Body length: 2.2 mm.

Comments. The species is very similar to Psl. paucispina Mohrig from Papua New Guinea. It differs by having a larger body size and darker colour, dense hairs on the flagellomeres, longer R 1, broader wings and a distinct semicircular bordered patch of bristles at the apex of the fore tibia. It belongs to the Psl. longicostalis group sensu Mohrig (2013).

Distribution. Australia (Queensland).
