Russelliana sp. 10

Material examined. Chile: 1 ♀, I Region, Province Parinacota, Misituni, 25.xi.1965 (I. Loksa) (MHNG, on slide).

Comments. The specimen resembles R. nana and queirozae in 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. They differ from the two species in the presence of a brown stripe on the forewing membrane stretching from a base of the vein Rs, along the vein Cu1b, to its apex. The specimen differs from R. nana in a shape of the forewing which is broadest in its middle and bears large surface spinules, and from R. queirozae in a longer cell m1 of the forewing.
