Descriptive notes. Male (Fig. 6A). Aedeagus feebly swollen laterally near middle (Fig. 5D, E); ventral processes of parameres abruptly thinned apically near bases, with apices widened and narrowly rounded, strongly bent to each other in ventral view (Fig. 5D), widened and rounded at apices, bent ventrally in lateral view (Fig. 5F); conjoint dorsal plate of parameres obviously longer than ventral processes, with apical margin arcuate and small-triangularly emarginate in middle, lateral margins diverging apically from middle, latero-apical angles widely rounded in dorsal view (Fig. 5E), and bent ventrally in lateral view (Fig. 5F); the emargination between conjoint dorsal plate and ventral process about half length of aedeagus (Fig. 5F).
Female. Internal organ of reproductive system (Fig. 7A): vagina stout and abruptly thinned at ventroapical portion into a very short and stout tube, where diverticulum and spermathecal duct arising separately; diverticulum very short and spiral, evenly thin along the whole length; spermathecal duct half shorter and thinner than apical tube of vagina; spermatheca provided with a spiral tube, progressively thinned apically and longer than diverticulum; accessory gland extremely long, almost three times longer than spermatheca.
Abdominal sternite VIII (Fig. 8A) moderately narrowed posteriorly, widely triangular at latero-apical angles, and widely emarginate on both sides and feebly emarginate in middle of posterior margin, with the portions between lateral and middle emarginations acute at apices and almost horizonital with apices of latero-apical angles.
