Diagnosis. E. parvula is a small species, with wingspan 5.0–6.5 mm. The forewing maculation is usually concentrated as plical and discal spots more clearly than in other species of the E. dispunctella complex. The male genitalia are characterized by the very long digitate process, its length twice that of the juxta lobes. See also E. moroccoensis below. The female genitalia of E. parvula have a very narrow ductus bursae, and the antrum and appendix bursae are absent.

Biology. Unknown.

Distribution. France, Greece, Italy, Morocco, Ukraine, Turkey.

Remarks. The holotype of E. parvula Parenti was not available for the present study. The specimens studied, including two paratype slides from Italy, Liguria, collected by J. Klimesch, are from the type locality and belong to the same samples from which the entire type series was designated. These specimens agree in all aspects with the original description of E. parvula. E. parvula is referred to as OTU 18 in Mutanen et al. (2015). The distribution record of E. parvula from Russia, Kola Peninsula, by Parenti (2002), referring to Kozlov and Jalava (1994), is a lapsus as such a record does not exist in that publication.

The aquarelle representing the habitus of the holotype – the only specimen known – of E. blancella by Traugott-Olsen (1992) has been painted to be unicolorous white. Since the specimen is extremely worn and nearly devoid of scales (cf. Fig. 19), this interpretation must be based on pure guesswork.
