Wingspan of adults is 21mm . The antennae are filiform. The forewings are pinky-red and yellow while the rear wings are light brownish. The costal edge is usually brownish or whitish in color. Tympanal organ ( Figs. 3f , 4f ): Bulla tympani which resembles a pouch is closed and concave. Tympanum and conjunktivum are on the same plane and the paraspinal line separating them has a thorny structure. There is a consecutive thorny rugae odontinae structure between the tympanum and fornix tympani. Fornix tympani is thin. Pons tympani is shaped like two attached noodles. The tergo-sternal sclerite is long and curvy, and the processus spiniforme is also curved. Zona glabra tympani is on a wide area.
