Small species. Body length
2.4 mm
. Fore wing length

Head in dorsal view with gena somewhat shorter than eye width. Antennal flagellum distinctly clavate, with 13–14 flagellomeres (
Fig. 101
); subbasal flagellomeres 1.6–1.8× as long as broad, and subapical flagellomere square. Clypeus lenticular, apically truncated, smooth with upper margin finely granulate. Malar space short, 0.4– 0.5× as long as basal mandibular width.
Mesosoma with notaulus absent or as very fine wrinkle. Propodeum with transverse carina very weak, medially obliterated, basal part 0.8× as long as apical area, and apical area about 1.8× as long as maximally broad (
Fig. 102
). Propodeal spiracle separated from pleural carina by about 2.0× diameter of spiracle.
Fore wing (
Fig. 18
