8473973736EA556EAEA8684644E0AE2A.taxon	diagnosis	Diagnosis. The morphology of the genitalia of E. copaquillaensis sp. nov. (Figs 3 - 6) closely resembles that of E. atacama (Vojnits, 1985) (Figs 8 - 11), with type locality near Freirina village in the Huasco Province of northern Chile, also recorded in a few localities of the Coquimbo Province (Vojnits 1985). E. atacama was originally described in Heteropithecia Vojnits, 1985, a monotypic genus synonymized with Eupithecia by Rindge (1987). This synonymy has been followed in subsequent studies (Rindge 1991; Parsons et al. 1999), including the redefinition of Eupithecia by Mironov and Galsworthy (2012). The males of E. copaquillaensis sp. nov. and E. atacama have two cornuti on the vesica, the larger of which is a narrow horseshoe-like piece with asymmetrical arms. However, the smaller cornutus is sub-cylindrical and curved on the distal half in E. copaquillaensis sp. nov., while it is depressed, squat and concave in E. atacama. The females of the two species have a mainly membranous corpus bursae with small teeth-like signa. However, the signa are grouped in a dense semicircular patch in E. copaquillaensis sp. nov., while those of E. atacamae are arranged in longitudinal stripes.	en	Vargas, Hector A.
