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.

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.
