Identification
Ground colour varies from light to dark rust-brown, AM and PM line thin and well defined, median line diffuse. Most specimens have diffuse black spots in the forewing subterminal space (but may be without any black at all). Similar to E. madusaria, which has a smooth rather than serrate forewing edge. E. johnsonaria has evenly deep serrations on the hindwing edge, obtusaria has the third notch conspicuously deeper; hindwing discal spot absent or faint in johnsonaria, well-defined in obtusaria. (1)
