Surstylus with 6 prensisetae submedially (Fig. 22). Tenth sternite furcated basally (Fig. 23). Paramere with ca. 3 sensilla (Figs 24, 25). Aedeagal opening slightly infundibular in ventral view (Figs 24, 25). Gonopods acute apically, with broadened, medially depressed projection dorsomedially (Fig. 27).
