    Head (Figs 7C, D and 8C): Oviform and very small in lateral view; antennae filiform, segments 1–9 well-preserved, scape and pedicel slightly compressed; flagellar segments slender and long, becoming thinner and shorter toward apex (moniliform in CNU-DIP-NN-2013206p/c in Fig. 8C); maxillary palpi segments not visible. Thorax (Figs 7A, B and 8E): Scutum well-developed, arched convex; scutellum depressed; haltere clearly depressed. Legs (Figs 7A, B and 8E): Forelegs: femur thicker than tibia; almost four-fifths of tibia; the 1st tarsomere longer than half of tibia, the 2nd–5th greatly thinned than the former. Mid legs: femur slightly thicker than tibia; tibial spurs minute; the 1st tarsomere slightly longer than the 1st tarsomere of forelegs. Hind legs: femur expanded almost equal to tibia; tibial spurs minute; tarsi not preserved. Wings (Figs 7E, 8D and F): Wing long and narrow (length: 7.1–8 mm, width: 2.3–3.2 mm), apex of wings not reaching the abdominal terminalia. Costal field long and thin, apex of Sc gradually tapering to the end; Rs arising almost from basal one-fifth of wing length, furcating proximad of fork of M1+2 bRs 4.4–5.6 times as long as r-m; crossvein m-cu slightly shorter than r-m; CuA arched near anal margin; vein A1 nearly straight, reaching posterior margin. Female genitalia (Fig. 8F): In lateral view, genitalia simple, with 2-segmented cerci.
