Male genitalia ( Figs 3–12 ). Anal tube nearly twice as long as wide in dorsal view; lateral margins not turned down in lateral view; apex with weak concavity ( Figs 11, 12 ). Anal column (paraproct) short. Pygofer with strongly angularly convex hind margins (hmp) in its middle (in lateral view) ( Fig. 8 ). Phallobase horseshoe shaped in lateral view, with weak median carina ventrally and with two large lateral folds basally ( Figs 3, 4 ). Processes of inner walls of dorsolateral lobes of phallobase (piph) (or earlike processes in Gnezdilov 2017a) large, each with semicircular lobe. Projections of ventral margins of dorsolateral lobes of phallobase covering aedeagal hooks (pvm) (or subapical lobes of phallobase in Gnezdilov 2017a) large, nearly square. Ventral phallobase lobe long, wide, nearly as long as dorso-lateral lobes, convex apically, with two lateral processes (lp) ( Fig. 1 ). Aedeagus horseshoe shaped in lateral view. Apical aedeagal processes long and wide in lateral view, weakly narrowing to rounded apices, slightly surpassing upper phallobase margin, each with short and rounded subapical projection (sap) ( Figs 5, 6 ). Ventral aedeagal hooks (vh) 0.3 times as long as aedeagus, slightly curved, acuminate apically and directed downwards ( Figs 3–6 ). Connective with elongate cup-like apodeme ( Fig. 4 ). Style with nearly straight hind margin (hms) and rounded caudo-dorsal angle (cda) ( Fig. 9 ). Capitulum of style on wide neck (ns) (in lateral view), wide and not narrowing apically (in dorsal view), with wide lateral tooth (lt) ( Fig. 10 ).

Female genitalia ( Figs 13–15 ). Sternum VII with deeply concave hind margin ( Fig. 13 ). Anal tube nearly twice as long as wide (in dorsal view) ( Fig. 15 ). Anal column (paraproct) short. Each gonocoxa VIII with large rounded lobe (gnl) ( Fig. 14 ).
