The wingspan of adults is 26mm . Antennae of females are filiform and males’ are unipectinate. It is very similar to the other species morphologically, the most significant difference being that it is smaller. The forewings are covered with light grey and black scales which are occasionally scattered and bear two transverse white bands in a zigzag pattern on the inner and outer parts. Rear wings are light-pearl grey and the fringes are dark-colored. Tympanal organ ( Figs. 3e , 4e ): Bulla tympani is closed and concave. The tympanum and conjunktivum are on the same plane. Tympanum has an oval shape and the spinula structure on top of it is prominent. The paraspinal line separating the tympanum and conjunktivum is not very prominent. There is a thorny rugae odontinae structure between the tympanum and fornix tympani. The conjunktivum has an oval shape. The fornix tympani is slightly thick. The pons tympani is shaped like two attached needles. The tergo-sternal sclerite is long and curved, the zona glabra tympani is wide. The processus spiniforme is curvy. The intersegmental thoraco abdominal membrane is shaped like “V”. Venula is either not prominent or absent.
