Descriptive notes. Male ( Fig. 1D View FIGURE ). Aedeagus feebly swollen laterally near middle ( Fig. 5A, B View FIGURE 5 ); ventral processes of parameres abruptly thinned apically near bases, with apices narrowly rounded and bent to each other in ventral view ( Fig. 5A View FIGURE 5 ), rounded at apices, feebly inclined ventrally in lateral view ( Fig. 5C View FIGURE 5 ); conjoint dorsal plate nearly as long as ventral processes ( Fig. 5C View FIGURE 5 ), with apical margin arcuate and small-triangularly emarginate in middle, lateral margins diverging apically, latero-apical angles widely rounded in dorsal view, ( Fig. 5B View FIGURE 5 ), and moderately inclined ventrally in lateral view ( Fig. 5C View FIGURE 5 ); the emargination between conjoint dorsal plate and ventral process about 1/3 length of aedeagus ( Fig. 5C View FIGURE 5 )).

Female. Internal organ of reproductive system ( Fig. 3D View FIGURE 3 ): vagina stout and abruptly thinned at ventroapical portion into a short and stout tube, where diverticulum and spermathecal duct arising separately; diverticulum very short and spiral, evenly thin along the whole length; spermathecal duct about 1/3 shorter and thinner than apical tube of vagina; spermatheca provided with a spiral tube, progressively thinned apically and distinctly longer than diverticulum; accessory gland long, about twice longer than spermatheca.

Abdominal sternite VIII ( Fig. 4D View FIGURE 4 ) moderately narrowed apically, acute at latero-apical angles, widely emarginate on both sides and feebly emarginate in middle of posterior margin, with the portions between lateral and middle emarginations widely triangular at apices and not reaching apices of latero-apical angles.

Distribution ( Fig. 37 View FIGURE 37 ). China (Sichuan).
