of E. tarapaca was until a few years ago the only specimen reported in the scientific literature from above 3000 m in the northernmost part of Chile (Vojnits 1985, 1992, 1994; Rindge 1987, 1991). In accordance with recent additions to other genera of Geometridae (Palacios et al. 2020; Vargas et al. 2020; Vargas 2021), the discovery of E. copaquillaensis sp. nov. confirms the need for further studies to characterize better the overlooked fauna of geometrid moths harbored by the high elevation environments of central Andes.
