A review of the Argyrogrammana fauna of the eastern Andes (Lepidoptera: Riodinidae: Symmachiini)

Abstract

The montane Argyrogrammana Strand, 1932, fauna (Riodinidae: Symmachiini) of the eastern Andes is reviewed. There are five described species from the region, and an additional three species are described here from Ecuador and Peru: A. janiceae Ahrenholz & Hall, n. sp., A. aurora Hall & Willmott, n. sp. (both occidentalis group), and A. cosnipata Hall, n. sp. (amalfreda group). A ninth species, known from only a single Peruvian female, is figured but not described. These nine east Andean endemics range in elevation from 550 to 2200 m.
