Additional description
. Male.
Head
. Dark brown. Eye bridge 3 facets wide. Antenna brown, necks short, brownish; 4th flagellomere with l/w-index of 2.5, with dense, pale hairs, shorter than the width of the basal node; palpus 3-segmented, basal segment with deep sensory pit and 1 bristle (sometimes 2).
Thorax
. Dark brown, scutum with rather long and dark dorsocentral as well as a few lateral bristles; scutellum with 2 long marginal bristles; postpronotum bare. Wing pale; R1 = 2/3 R; R5 with dorsal macrotrichia only; C = 2/3 w; y somewhat shorter than x, without macrotrichia; posterior veins weak, without macrotrichia. Haltere short, brown. Legs dark brown; fore tibia with a broad comb (somewhat wavy) of pale bristles; spurs of middle and hind tibia equal in size, thin, somewhat longer than the width of tibia at apex; claws without teeth.
Abdomen
. Dark brown, with sparse, rather short brownish hairs. Hypopygium dark brown, with broad v-shaped ventral base, without lobe or bristle patch; gonocoxites with fine and rather short hairs on the inner ventral margin, on ventral apex with 2 strong megasetae (
Fig. 10
D); gonostylus weakly bulbous, without apical tooth, with 6‒7 short apical/subapical spines among the dense hairs of the apex; tegmen small, wider than long, truncate apically, with large area of teeth and with short ventral parameral apodeme; aedeagus rather long and robust. Body length: 3.0 mm.
Comments
. This species is characterized by a dark body colour; palpus with a sensory pit, a robust gonostylus with 6‒7 short spines among dense bristles at the apex and 1 thick megaseta on the ventral apex of the gonocoxites.
