Argentina : 1 ♂ , 2 ♀ , Province Mendoza , above Villa Vicencia , 50 km NW Mendoza , 1800 – 2200 m, 18.i.1997 , low scrub ( D. Burckhardt ) #15 ( NHMB , dry). Comments. The specimens resemble R. nana and queirozae in a pale yellow body colour, in an oblong-oval paramere bearing an apico-anterior process on a pedicel, situated interiorly to an apico-posterior lobe, a cuneate female proctiger with a dorsal margin conspicuously bent downwards in its apical third and bearing short thick bristles, and in a cuneate subgenital plate bearing a very long apical process. The male specimen differs from the two species in a shape of the process and a lobe of the paramere. The specimens differ from R. queirozae in long genal processes, a shape of the forewing which is broadest in its apical third, and a female subgenital plate bearing short thick bristles in the apical third.
