Abstract
Argyrotaenia socoromaensissp. nov. (Lepidoptera, Tortricidae, Tortricinae, Archipini) from the arid Andes of northern Chile is described and illustrated. Adults are sexually dimorphic, with differences in wing size, shape and pattern. The larvae feed on Stevia philippiana Hieron. (Asteraceae) and Lupinus oreophilus Phil. (Fabaceae). Genetic distance between DNA barcodes of male and female adults reared from larvae collected on the two hosts was 0–0.2% (K2P). The discovery of A. socoromaensissp. nov. represents the first record of the genus Argyrotaenia Stephens, 1852 and the tribe Archipini for the Chilean fauna of Tortricidae.
