Labial palpus dark grey, its length equal to the eye’s diameter. Head, thorax, patagium, and tegula dark grey. Legs grey, outer side of tibia and tarsus creamy grey. Forewing upperside grey, with four wavy lines running from costal margin to anal margin; antemedial stripe dark grey. Outer margin toothed. Marginal area from R4 to Cu1 dark grey. Forewing underside light grey with wavy postmedial and submarginal lines. Marginal area from R4 to Cu1 dark grey. Hindwing upperside grey with two wavy postmedial lines; marginal area from Rs to Cu1 dark grey. Outer margin with a strong ledge in the area of Rs and M1 veins. Hindwing underside repeats the pattern of the upperside; marginal area from Sc+R1 to Cu1 dark grey. Abdomen grey. Male genitalia: Tegumen broad; uncus and gnathos form a typical “bird- beak” structure; valva slightly elongated, rounded apically. Saccular process of valva typical for the genus.
