On micromoths (Lepidoptera, Ypsolophidae) associated with shrubs (Fabaceae) in the arid western slope of the central Andes.

Latreille, 1796 (Lepidoptera, Ypsolophidae) is a genus comprised mostly of Holarctic micromoth species with a fairly broad range of larval hosts (e.g. Aceraceae, Rosaceae, and Fagaceae). The only previous record of herbivory on a representative of the South American genus DC. (Fabaceae) was based on the discovery of Vargas, 2018 larvae feeding on Meyen in the Andes of northern Chile. Further surveys revealed Phil. as another host for , and Meyen as the single host of sp. The genetic distance between DNA barcodes of the two micromoth species was 7.9-8.1% (K2P). These results suggest narrow host ranges for -feeding and highlight the need to further explore the taxonomic diversity of these micromoths in other South American environments.
