Male abdomen: Tergites 1+2-6 well developed, lengths of 3-6 subequal; tergite 7 narrow; sternites 3, 4, 5 generally as rectangular plates, slightly wider than long, lateral margins shallowly arched; sternite 5 slightly wider subposteriorly; sternites 6, 7 lacking, neither segment forming an annulus. Male terminalia (Figs 72-75): Epandrium in lateral view (Fig. 73) broadly trapezoidal, higher than wide, narrowed dorsally, anterior margin nearly straight, posterior margin straight on dorsal 2/3 thereafter ventrally forming a robust truncate extension; surstylus almost as long as epandrium, extended from ventral margin of epandrium in nearly oblique alignment with it, in lateral view (Fig. 73) elongate, robustly developed, distinctly tapered, apex recurved, anterior margin very shallowly sinuous, posterior margin swollen medially, apical 1/4 tapered to moderately acute point, partially recurved, bearing medial, elongate setula from posteromedial extension; hypandrium in ventral view (Fig. 74) moderately robustly V-shaped, arms tapered toward attachment with epandrium, anterior portion robustly developed with lateral margins sinuous, anterior margin broadly pointed; pregonite roughly triangular, with anterior margin receded and slightly round corners (Fig. 74); postgonite in ventral view (Fig. 74) convoluted, with relatively small, narrow lobe bearing 6 marginal and apical setulae, in lateral view (Fig. 75) lobe bar-like, with 3 visible apical, short setulae; phallus in J-shaped, bearing apical hairs, in lateral view (Fig. 75) obscured by the postgonites; phallapodeme in lateral
