Aedeagus. Median lobe ( Figs. 7 F–G) narrowly ovate and widest in basal fourth, apical process constricted basally and convergent at apex in ventral aspect; internal sac elongate. Apical lobe of paramerites ( Fig. 7 H) with four setae; a-seta longest, c- and d-setae shorter than b-seta, close together and positioned apically. Spermatheca. Bursa globular apically, with small umbilicus; duct simply coiled ( Fig. 7 I).
