The specimen resembles R. adela , bicolorata , intermedia and xantha , in long genal processes and long antennae. It differs from the four species in very dense surface spinules on the forewing membrane, present in all cells and leaving no spinule-free stripes along the veins, and from R. adela , intermedia and xantha in a shape of the forewing which is broadest in its middle.
