Description.

Length of body 4.65 - 4.94 mm (n=2).

Head brown with dark setae. Three equally sized ocelli in a triangular arrangement. Clypeus subrounded. Palpus with 5 light brown setose segments with ratios of 1: 1.17:1.58: 2.25:4.33. Mouthparts brownish. Antenna with 2+14 segments. Scape, pedicel and base of first flagellar segment light brown, rest of flagellomeres brown. Scape with sparse setae including dorsoapicals extending to middle of pedicel. Pedicel with sparse and all flagellomeres with dense setae. First flagellomere 3 times as long as wide, succeeding segments gradually shorter. Apical flagellomere cylindrical, about three times as long as wide.

Thorax brown. Scutum covered with pale setae including long lateral hairs. Lateral parts of thorax slightly paler than scutum. Antepronotum with numerous long pale hairs. Proepisternum with numerous shorter setae. Laterotergite and mediotergite with upward directed hairs. Anepimeron and metepisternum with short setae, anepisternum bare. Scutellum with setae not in distinct pairs.

Legs. Fore coxa light brown with hind margin and apical fourth yellow. Mid and hind coxae brown, apically slightly paler. All trochanters brown. All femora and tibiae yellow with apical brown markings. All tarsi dark brown. Tibiae with irregularly arranged setae but without distinct bristles. Fore tibia with a spur 0.18 of basitarsus length. Mid and hind tibiae both with two equal spurs, 0.19 and 0.21 of basitarsus length, respectively. Ratio of femur to tibia for fore, mid and hind legs: 1.00; 0.82; 0.81. Ratio of tibia to basitarsus for fore, mid and hind legs: 1.15; 1.57; 1.86.

Wing hyaline. Length of wing 4.00 - 4.23 mm (n=2). Ratio of length to width 2.83. Veins light brown, setose on both surfaces. Wing membrane with dense irregularly arranged microtrichia and with few macrotrichia in anal area and close to wing tip below of R1 and R5. C not produced beyond apex of R5, which is strongly sinuate. Sc ends in C at the level of beginning of medial fork. Sc2 situated at the level of middle of bM-Cu. M1basally obsolete. Cubital fork begins slightly before the base of r-m. Haltere pale with brownish knob. Both, stem and knob with short setae.

Abdomen brown with segments I–IV lighter. Terminalia (Figs 3a, 3b, 3c) light brown. Cercus distinctly two-segmented, segments with subequal length, proximal segment more than twice as wide as distal. Tergite VIII subquadrate, as large as tergite IX and tergite X together. Sternite VIII with deep ventral cleft. Gonapophysis IX well sclerotized and visible in lateral view. Hypoproct with apical incision, exposed in ventral view.

Male (Figs 2b, 3d).

Length of body 5.36 - 6.32, 5.65 mm (n=5). Length of wing 4.37 - 5.30, 4.76 mm (n=5), ratio of length to width 2.55 - 2.82, 2.64 (n=5). Coloration and other non-terminal characters similar to female except anepisternum, which has short setae on upper part. Terminalia brown. Gonostylus simple, without any additional lobes or spines, slender, tapering, curved medially and covered with short setae.
