Male genitalia (Fig. 3). Tergite VIII brown, with lighter areas around alveoli; setation abundant; spinose area approximately rectangular in dorsal view; flanked by membraneous, less sclerotized areas. Segment IX in lateral view ventrally slightly concave distally; in caudal view wider dorsally than ventrally; with long, round, wedge-shaped protrusion in dorsal half (best seen in ventral view). Superior appendages in lateral view suboval, curved obtusely caudad in proximal fifth, proximally dorsal somewhat protuberant, tips slightly curved dorsad, longest in anterioposterior axis: approximately 2 times longer than high; in dorsal view medially concave, tips converging; medial transverse section lateroventrally curviconvex suboval. Intermediate appendages in lateral, dorsal and caudal views dorsally with 2 distinct tips, the proximal tip rounded, rough, the distal tip pointed, smooth; in caudal view approximately an isoceles trapezium. Inferior appendages in lateral view roughly triangular, proximally constricted, ventrocaudally slightly concave; in dorsal and ventral views tips converging; in ventral view with longitudinal groove delimiting medial lobe. Parameres simple, rodlike, medially and distally somewhat bulbous.
