Diagnosis. Crown and pronotum red; forewings dark. Male: dorsal margin of pygofer, in lateral view, posteriorly elevated; aedeagus thin and elongated, curved dorsally, with a pair of fine apical processes.

Female terminalia. Abdominal sternite VII, in ventral view (Fig. 8), with lateral margins slightly parallel, lateroposterior margins broadly rounded, and posterior margin with a short median triangular projection, and occasionally with a lateral small projection on each side; surface with scattered microsetae. Pygofer, in lateral view, produced posteriorly; surface with scattered microsetae and macrosetae on ventral and posterior regions. First valvifers, in lateral view, ovoid; with small spiniform processes on ventral region. First ovipositor valvulae, in lateral view, slightly broadened beyond basal curvature; dorsal and ventral sculptured areas formed mostly by linear processes; apex acute and slightly curved upward (Fig. 20), with denticles on dorsal margin. Second valvulae, in lateral view, broadened beyond basal curvature; dorsal margin of blade bearing 24 to 26 different teeth: proximal region with subtriangular teeth, without denticles, and distal region of valvulae with teeth rectangular, with denticles on dorsal margin (Fig. 32); ducts not reach the teeth; apex narrowly rounded (Fig. 44), with denticles on dorsal and ventral margins; preapical ventral prominence conspicuous.
