Russelliana sp. 6

Material examined. 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.
