Bolivia : 1 ♀ , Department Oruro , Province Cercado , 2 km W Leque Palca , 17°38.2'S 66°58.4'W , 3950 m , 23.iii.2001 ( A. Freidberg ) ( NHMB , dry) ; 1 ♀ , Department La Paz , Province Pedro Domingo Murillo , 6 km NE La Paz , 16°25.7'S 68°04.3'W , 4130 m , 19.iii.2001 ( A. Freidberg ) ( NHMB , dry) ; 1 ♀ , same but 14 km S El Alto , 16°40.1'S 68°11'W , 3900 m , 20.iii.2001 ( A. Freidberg ) ( NHMB , dry). Comments. The specimens resemble R. fabianae and viscosae in a short antenna, in a yellow forewing membrane, in a female proctiger with a convex, subapically strongly indented dorsal margin, and a subglobular subgenital plate. They differ from the two species in longer genal processes, and from R. viscosae in the presence of very dense surface spinules in all cells of the forewing membrane, leaving no spinule-free stripes along the veins.
