Maoershan, 25°54’N 110°27’E , alt. 1,550–1,750 m 24.vii.2012 , Hu & Song leg. (SNUC). Comment. The original description is based on a single male with a probably slightly damaged aedeagus (Peng et al. 2012). The species is most likely endemic to the Maoer Shan ( Fig. 1 ). For illustrations of the habitus and the male sexual characters see Fig. 3 and Peng et al. (2012). The aedeagus and the previously unknown female sexual characters are as follows: aedeagus as in Figs 3G, 3H; ventral process asymmetric and distinctly angled subapically (lateral view); dorsal plate sclerotized and long; internal sac without sclerotized structures; posterior margin of female tergite VIII (Fig. 3A) moderately pointed at middle; female sternite VIII (Fig. 3B) longer than tergite VIII, apical margin broadly convex; female tergite IX (Fig. 3C) with short antero-median portion and with slender postero-lateral processes, median portion with median suture; female tergite X approximately five times as long as antero-median portion of female tergite IX (Fig. 3C).
