( Fig. 18 A – C )

Description. Male. Head. Eye bridge 2–3 facets wide. 4 th flagellomere with a l/w-index of 2.4, haired as long as width of basal node. Palpus 3-segmented, short; basal segment with a small shallow sensory pit and 1 bristle.

Thorax. Brown. Scutum with brownish hairs. Wing pale; R 1 short = 1/3 R; c somewhat longer than ½ w; y short = 1/ 2 x, bare; posterior veins bare. Haltere short, brownish. Legs paler than thorax; tibial organ small, comb-like; spurs of middle and hind tibia with two long but unequal spurs; claws toothless. Abdomen. Brown. Hypopygium brown, ventral base more densely haired than the inner ventral margin of the gonocoxites; gonocoxites longer than the gonostylus; gonostylus elongate, slightly pointed towards the apex and bulbous in the middle of the inner sides, without an apical tooth but with 3 equal spines at the apex. Tegmen large, wider than long. Aedeagus rather short, with a distinct furca. Body size: 1.2 mm.

Comments. The species is characterized by a short palpus with a shallow sensory area, wings with a short y and a rather short C, hypopygium with an elongate gonostylus, bulbous in the middle of the inner side, without an apical tooth but with 3 equally long spines.
