= Bradysia planistylata Vilkamaa, Hippa & Mohrig, 2012 syn. n. [ Vilkamaa et al. (2012c): 38 ‒39, fig. 10 A‒D; Mohrig

(2016): 28, fig. 32 a‒c; plate III, fig. 32].

Type locality. New Caledonia.

Holotype: Bradysia planistylata Vilkamaa, Hippa & Mohrig, 2012 , male.

Additional description. Male. Head. Brown. Eye bridge 3 facets wide. Antenna lost; palpus 3-segmented, basal segment with sensory pit and 4‒5 bristles. Thorax. Brown, scutum with a few longer prescutellar and lateral bristles; postpronotum bare. Wings brownish; R1 = 3/4 R; R5 with dorsal macrotrichia only; C = 2/3 w; y = x, without macrotrichia; posterior veins distinct, without macrotrichia. Haltere short, brownish. Legs brownish; fore tibia with a comb of somewhat wavy brown bristles; spurs of middle and hind tibia equal in size, longer than the width of tibia apex; claws without teeth. Abdomen. Brown, with rather short hairs. Hypopygium brown, with broad open ventral base, strongly contoured, without lobe or patch of bristles; gonocoxite with short hairs on the inner ventral membrane, the ventral inner margin with rather long bristles; gonostylus elongate, without apical tooth, flattened on the inner side and with shovel-like apex, densely covered with short spine-like bristles; tegmen apically rounded, with large area of teeth and a long ventral parameral apodeme; aedeagus rather long. Body length: approximately 4.0 mm.
