= Bradysia seticornis Vilkamaa, Hippa & Mohrig, 2012 syn. n. [ Vilkamaa et al. (2012c): 39 ‒41, fig. 11 A‒D].

Type locality. New Caledonia, Riviere Bleue National Park , rainforest.

Holotype: Bradysia seticornis Vilkamaa, Hippa & Mohrig, 2012 , male, 21.vii.1992 (in Museum National d´Histoire Naturelle, Paris).

Additional description. Male. Head. Brown. Eye bridge 3 facets wide. Antenna brown, necks rather short, brownish, weakly bicoloured; 4th flagellomere with a l/w-index of 4.0, densely setose, somewhat longer than the width of the basal node; palpus long, 3-segmented, basal segment with sensory pit and 2-3 bristles. Thorax. Brown, scutum with three somewhat darker stripes, with long prescutellar as well as a few lateral bristles; scutellum with four longer marginal bristles; postpronotum bare. Wing pale; R1 = 3/4 R; R5 with dorsal macrotrichia only; C = 2/3 w; y somewhat longer than x, with 1-2 macrotrichia; posterior veins without macrotrichia. Haltere short, brownish. Legs yellowish-brown; fore tibia with a broad comb of 6‒7 pale bristles; spurs of middle and hind tibia equal in size, somewhat longer than the width of the tibia apex; claws without teeth. Abdomen. Brown, with short, sparse, pale hairs. Hypopygium brown, with broad v-shaped ventral base, without lobe or patch of bristles; gonocoxite with short, sparse, fine hairs on the inner ventral margin; gonostylus weakly bulbous, without apical tooth, with one spine dorsally located and 4 apical spines (the two centrally located spines are longer); tegmen apically rounded, with a large area of teeth and with strong ventral parameral apodeme. Body length: 3.8 mm.

Comments. This species is characterized by a dark brown thorax and yellowish legs, long densely hairy flagellomeres; bulbous gonostylus, with one dorsally located spine and 4 apical spines; and a large apically rounded tegmen, with a large area of teeth. It belongs to the B. hilaris group. The species is similar to B. exsequialis (Skuse) with respect to the shape of the gonostylus, but it differs in the arrangement of the apical spines and the shape of the tegmen, with a stronger ventral parameral apodeme in B. pictipes . Sciara notata Skuse , and Bradysia seticornis Vilkamaa, Hippa & Mohrig from New Caledonia are identical to B. pictipes Skuse in all details.

Distribution. Australia (New South Wales), New Caledonia.
