Comments. The specimen resembles R. adunca and caunda in a colourless forewing membrane bearing faint surface spinules. The specimen differs from the two species in longer genal processes and a shape of the paramere bearing an apico-posterior lobe which is strongly bulged posteriorly. The latter resembles a condition in R. disparilis but the specimen differs from R. disparilis in the presence of surface spinules on the forewing membrane which are absent in R. disparilis.
