Aedeagus moderately swollen laterally near middle ( Fig. 2G, H ); ventral processes of parameres abruptly thinned apically near bases, with apices acute and directing laterally in ventral view ( Fig. 2G ), pointed at apices, inclined ventrally in lateral view ( Fig. 2I ); conjoint dorsal plate of parameres feebly longer than ventral processes ( Fig. 2G–I ), with apical margin roundly and moderately emarginate in middle, lateral margins diverging apically, latero-apical angles rounded in dorsal view ( Fig. 2H ), and feebly bent ventrally in lateral view ( Fig. 2I ); the emargination between conjoint dorsal plate and ventral process about 1/4 length of aedeagus ( Fig. 2I ).

Rhagonycha albolimbata Pic, 1926 ; B. Rh. furcatiformis Wittmer, 1997 ; C. Rh. hubeiana Wittmer, 1997 ; D. Rh. limbatella Wittmer, 1997 . Scale bars: 1.0 mm. Female. Internal organ of reproductive system ( Fig. 3C ): vagina stout and abruptly thinned at ventroapical portion into a very short tube, where diverticulum and spermathecal duct arising separately; diverticulum short and spiral, evenly thin along the whole length; spermathecal duct very short and stout; spermatheca provided with a spiral tube, progressively thinned apically and longer than diverticulum; accessory gland extremely long, about three times longer than spermatheca. Abdominal sternite VIII ( Fig. 4C ) moderately narrowed apically, widely rounded at latero-apical angles, and feebly bilobed in middle of posterior margin. Distribution ( Fig. 36 ).
