Vein 10 of the forewings arising independently of 9; arising out of 11 and anastomosing with 9 to form a simple areole. Hindwings exhibiting a tubular vein 5. Vein 5 of the hindwings arising from about the middle of the transverse vein, or arising from below the middle of the transverse vein (?). Vein 8 of the hindwings approximated to or anastomosed with the upper margin of the cell to the middle or beyond.

Posterior tibiae of males 4-spurred.
