Antenna brown, scape darker. Mouth parts blackish brown. Thorax . Prothorax blackish brown. Mesonotum pale brown; anterior surface of scutum blackish brown; anterior margin of lateral lobe and postero-lateral margin of anterior lobe of scutum black, posterolateral margin of lateral lobe and posterior part of anterior lobe white; scutellum brown, anterior margin blackish brown; postnotum brown. Metanotum pale brown, anterior lobe of scutum brown with white longitudinal line medially; scutellum brown, anterior margin blackish brown. Meso- and metapleurites blackish brown, with white longitudinal band medially. Legs. Brown; fore leg except tarsus and hind tibia paler; all femora with pair of blackish brown spots ventrally; all tibiae with blackish brown band near distal end; middle femur with paler region medially. Forewing ( Fig. 36B ). Spots in cell a 1 apparent. Opposing spots in cell r large, almost touching each other. Proximal band broad, broadly interrupted just beyond fork of M + Cu, strongly constricted at anterior end in cell cua, including triangular pale spot. Median spots dense, some spots fused with each other, forming larger markings. Distal band apparent, broad in cell r 5 . Spot on roof of cell m 3 apparent and broad. Submarginal spots apparent; spot in cell r 1 and m 3 smaller than others. Marginal clouds apparent and dark. Hindwing. Hyaline with faint brown marking in cell cup; veins brown. Abdomen . Mostly black ventrally, each segment with blackish band dorsally and laterally. Terminalia . Clunial arm long and narrow, sickle-like in shape and forming free process apically. Epiproct ( Fig. 37E, F ) chair-shaped, postero-dorsal margin with strongly projected transversal ridge, its median part with square-shaped thin keel; epiproct lobe long and wide, broader than long, narrowing dorsally, posterior surface slightly swelling. Paraproct: ventro-lateral band short, triangular; distal process long, directed upward. Hypandrium ( Fig. 37G ): left process needlelike, almost straight, directed posteriorly; right process lamellate; median tongue small and short, length/width ª 2, nearly parallel sided and rounded apically, dorsal surface covered by weak denticles.
