Three pairs of posts dc, without pres dc; acr weak and short, continuing in a posts row to base of scutellum; 1 strong presutural seta; posterior npl much farther from notopleural suture than anterior npl; 1 strong sa, psa absent; two pairs of sc. Forefemur with row of pv, mid femur with row of av. Male genitalia: Epandrium base as wide as apex in posterior view; cerci long, thickened at base and slender at apex. Gonite falcate at base in lateral view. Female genitalia: Cerci flatiron­shaped in lateral view, yellow at base and yellow at apex. Sternite 8 divided into 2 triangular sclerites.
Description. Male body length 2.2–2.4 mm, wing length 2.5–2.7 mm.

Setulae and setae of head black. 1 lateral vertical seta as long as 1 medial vertical seta; 1 pair of strong ocellar setae; 4 lateroclinate orb, 1st and 3rd setae thin and short. Slightly projecting face black with greenish blue dense microtomentum, with 3 long facial setae as strong as oral setae on each side. Gena with 1 very strong seta. Antenna black; arista short pubescent.
