Description. Male. Head. Brown. Eye bridge 3 facets wide. Antenna brown; 4th flagellomere with l/w index of 2.5, hairs somewhat longer than the diameter of the basal node, neck rather long, about 1/4 of the length of the basal node. Palpus yellow, 3-segmented, basal segment with one bristle and a flat area of sensillae. Thorax.

Brown. Scutum with rather long dorsocentral and a few stronger lateral and prescutellar bristles; scutellum with 2 long marginal bristles. Postpronotum bare. Wing broad and brownish; R1 short, = 1/2 R; R5 with ventral macrotrichia in the distal half; C = 2/3 w; y = x, without macrotrichia; posterior veins without macrotrichia. Haltere short and brown. Legs yellow, tarsi darkened; fore tibia with a broad row of bristles (8–10) at the inner apex; middle and hind tibia with two unequal spurs. Claws without teeth. Abdomen. Brown, with sparse hair. Hypopygium brown, ventral base sparsely hairy; gonocoxite ventrally with short sparse hairs at the inner border; gonostylus narrow, on the apex with 4 somewhat unequal spines: one apical spine long and tooth-like, a second above the apex, a third near the base of a long apical spine and the fourth below the apex. Tegmen wider than long, flatly rounded apically, sclerotiZed laterally. Aedeagus rather short. Body length: 1.2 mm.

Comments. The species is characteriZed by unequal spurs on the middle and hind tibia and a wide row of bristles on the apex of the fore tibia. The gonostylus is elongate with 4 unequal spines.
