Fore wing grey, transparent, veins light brown.

Male 2S abdominal apodemes extended to hind margin of third sternite (Fig. 3 c).

Pygofer side (Fig. 3 d) short, weakly denticulated, without microsetae; dorsal appendage (Figs 3. e) tapering towards apex, extremely long, extended far beyond hind margin of lobe. Ligament (Fig. 3 d) relatively broad, integrated with pygofer dorsal appendage. Subgenital plate (Figs 3 d, f) exceeding hind margin of pygofer side, pointed apically, constriction short, at about midlength; with about 4 macrosetae near lateral margin and numerous microsetae on distal disc, marginal microsetae extended from near base to apex except in area of constriction. Style (Figs 3 g, i) sharply curved dorsad apically, apical part long, preapical lobe distinct. Connective (Figs. 3 h, i) with lateral arms relatively long. Aedeagal shaft (Figs 3 h, i) compressed, apical processes slightly asymmetrical, directed ventrad; branch of upper atrial appendage long, lamellate; ventral process broad, expanded subbasally in ventral view, surpasses midlength of shaft, apex concave.
