Head with ocellar triangle finely tuberculate ( Fig. 5 View FIGURES 1 – 8 ), with a few reticulate lines at posterior margin, ocellar setae III just outside ocellar triangle. Antennae 9 -segmented ( Fig. 7 View FIGURES 1 – 8 ); sense cone on VI arising near base of segment but extending beyond apex of IX; sense cones on III and IV stoutly U-shaped. Pronotum with complex irregular sculpture and markings within the reticles ( Fig. 5 View FIGURES 1 – 8 ). Metanotum longitudinally reticulate with internal markings ( Fig. 8 View FIGURES 1 – 8 ). Fore wing typical of genus, major setae scarcely longer than microtrichia, anteromarginal cilia arising ventrally well behind margin. Tergites II –VII strongly reticulate with complex short longitudinal sculpture lines on posterolateral areas ( Fig. 6 View FIGURES 1 – 8 ), VIII with long marginal comb, IX with many discal microtrichia.

Measurements (holotype female in microns). Body length 1050. Head, length 50; width across eyes 160. Pronotum, length 80; width 175. Fore wing length 750. Antennal segments III –IX length 27, 30, 25, 20, 7, 12, 12.
