Esperia oliviella is a species of gelechioid moth from Europe and the Near East. In its superfamily, it is placed in the genus Esperia within the subfamily Oecophorinae of the concealer moth family (Oecophoridae). Some authors, in particular those that follow a "splitting" approach to gelechioidea systematics and taxonomy, recognize Dasycera as an independent genus. The present species is thus not infrequently listed as Dasycera oliviella; indeed, it is (under its junior synonym Tinea aemulella) the type species of Dasycera.
