As compared to the general description of the species group, the fore wing is overlaid with seven spots at basal part, and with a single short black stria running parallel with costa. Hind wing black, yellow at base, with strong costal brushes; cilia yellow. In the male genitalia (Fig. 10) the labis is broad and short. Valva wide, bean-shaped, distal edge strongly curved, cucullus with short, strong, acute, curved process; sacculus wide with a less prominent weakly sclerotized field. Female genitalia (Fig. 11) the apophyses anteriores are cuneiform, not as acute as in the other species.
