Head width 0.79–0.88 mm; pubescence of clypeus and lower parocular area, simple, relatively shorter and sparse; piligerous points separated by distance about as long as hair length in discal area of clypeus; only simple hairs or very shortly branched hairs on juxtaclypeal area ( Fig. 4View FIGURES 1 – 5); malar space short, 1 x diameter of fl. 3 ( Fig. 4View FIGURES 1 – 5); clypeus short, about 1 / 3 of its maximum width and 1 / 5 of clypeocellar distance; integument of upper gena with fine tessellation; posterior margin of tibia III sinuous, posterior parapenicillum markedly sinuous, S-shaped ( Fig. 5View FIGURES 1 – 5); keirotrichiate area on inner surface of tibia III with a glabrous area medially.

Male ( Figs. 11–15View FIGURES 11 – 15; Tab. I). SVI with broad hairy medial area slightly concave ( Fig. 11View FIGURES 11 – 15); median projection of SVII broader and V-shaped ( Fig. 12View FIGURES 11 – 15); gonocoxite as long as wide and not projecting laterally on the gonostylus articulation ( Figs. 14, 15View FIGURES 11 – 15).
