Descriptive notes. Male ( Fig. 6B View FIGURE ). Aedeagus moderately swollen laterally near middle ( Fig. 5G, H View FIGURE 5 ); ventral processes of parameres abruptly thinned apically near bases, with apices widened and rounded, bent to each other in ventral view ( Fig. 5G View FIGURE 5 ), wide and almost straight in lateral view ( Fig. 5I View FIGURE 5 ); conjoint dorsal plate of parameres nearly as long as ventral processes ( Fig. 5I View FIGURE 5 ), with apical margin moderately deeply and roundly emarginate in middle, lateral margins feebly converging apically, latero-apical angles truncate in dorsal view ( Fig. 5H View FIGURE 5 ), and feebly inclined ventrally in lateral view ( Fig. 5I View FIGURE 5 ); the emargination between conjoint dorsal plate and ventral process about 1/3 length of aedeagus.

Female. Internal organ of reproductive system ( Fig. 7B View FIGURE 7 ): vagina stout and abruptly thinned at ventroapical portion into a long and thin tube, where diverticulum and spermathecal duct arising separately; diverticulum moderately long and spiral, evenly thin along the whole length; spermathecal duct very short and about 1/8 length of apical tube of vagina; spermatheca provided with a spiral tube, progressively thinned apically and longer than diverticulum; accessory gland long, about twice longer than spermatheca.

Abdominal sternite VIII ( Fig. 8B View FIGURE 8 ) strongly narrowed posteriorly, widely rounded at latero-apical angles, and trapezodinally protuberant in middle of posterior margin.

Destribution ( Fig. 39 View FIGURE 39 ). China (Xizang, Yunnan) .
