Diagnosis. Male: pygofer processes, in ventral view, curved strongly mesally at base and subparallel apically; style truncate apically; aedeagus with a pair of elongated basal processes.

Female terminalia. Abdominal sternite VII, in ventral view (Fig. 9), with lateral margins slightly convergent posteriorly, lateroposterior margins subtriangular, and posterior margin with a median long shallow emargination; surface with scattered microsetae. Pygofer, in lateral view, not produced posteriorly; surface with scattered microsetae and a few macrosetae on posterior and ventral regions. First valvifers, in lateral view, subsquare; with small spiniform processes on ventral region. First ovipositor valvulae, in lateral view, rectilinear beyond basal curvature; dorsal sculptured area formed mostly by linear processes arranged in oblique lines; ventral sculptured area formed mostly by scale-like processes; apex acute (Fig. 21), with denticles on dorsal and ventral margins. Second valvulae, in lateral view, broadened beyond basal curvature; dorsal margin of blade bearing 28 to 30 continuous teeth, each tooth subtriangular with posterior side longer, with denticles on anterior and posterior margins (Fig. 33); ducts extending toward teeth; apex rounded (Fig. 45), with denticles on dorsal and ventral margins; preapical ventral prominence conspicuous. Gonoplacs, in lateral view, with spiniform processes on ventral margin; apex rounded.
