The specimens resemble R. nana and queirozae in a pale yellow body colour and in an oblongoval paramere bearing an apico-anterior process on a pedicel, situated interiorly to an apico-posterior lobe. They differ from the two species in the absence of genal processes, and a shape of the process and a lobe of the paramere.
