Identification
Adult: forewing dull yellowish to brown with dark AM and PM lines; AM line almost straight, slightly curved near inner margin; PM line convoluted, situated fairly close to outer margin, with convex multi-toothed lobe in upper half and concave single-toothed lobe in lower half; dark rectangular reniform spot touches or almost touches concave portion of PM line; light brownish shading in subterminal area is diffuse and does not form a distinct subterminal line; hindwing similar to forewing in color and markings but lacks AM line and is paler toward base
Range
