Resumen

The syntypes of Thecla coronata Hewitson, 1865 and holotype of Thecla watkinsi Lathy, 1926 were examined and their identity is discussed. A lectotype is designated for Thecla coronata Hewitson, 1865 in order to stabilise the nomenclature. A new Andean species, Evenus felix sp. nov., is described. Distribution data indicate extensive sympatry of both species in the eastern Andes. We present diagnostic characters for the new species including differences in wing pattern, male modified wing scale patches and genitalic brush organs, and mitochondrial COI DNA “barcode” sequences. A discussion and natural history notes follow for both species. We document adults and their genitalia, and distribution data and maps are provided.
