Comments. The specimens resemble R. adela , bicolorata , intermedia and xantha , in long genal processes and long antennae. They differ from the four species in very sparse surface spinules in the apical part of the forewing membrane and their absence in the cell c+sc, and a different shape of the paramere bearing an apico-anterior process on a long pedicel. The specimens differ from R. adela in a yellow forewing membrane and a female proctiger with a dorsal margin bent downwards, and from R. bicolorata in an evenly yellow body colour and a shape of the forewing which is broadest in its apical third.
