Description. Male terminalia: Epandrium broadened on posterior margins, wider than 3/5 high, pointedly protruded ventrally ( Fig. 7 ). Cercus lacking pubescence ( Fig. 7 ). Surstylus with 8 prensisetae submedially ( Fig. 8 ). Tenth sternite sclerotized and furcated basally ( Fig. 9 ). Paramere with ca. 4–6 sensilla ( Figs 10, 11 ). Aedeagal opening narrow, aperture-like in ventral view ( Figs 10, 11 ). Gonopods slightly roundly protruded, with oval, strong projection dorsomedially ( Fig. 13 ). FIGURES 7–13.
