Diagnosis. E. dalmatiensis is similar to E. dispunctella and E. grandella. The phallus is longer in E. dispunctella as compared to E. dalmatiensis and E. grandella, with its length equal to the length of the valva. The phallus is shorter than the valva in both E. dalmatiensis and E. grandella. E. grandella, a poorly known species, is large, with a wingspan of 11–12 mm, as compared to E. dispunctella and E. dalmatiensis whose wingpans range from 7–9 mm, and its valva is broader than in E. dalmatiensis. The female is unknown.

Biology. Unknown.

Distribution. Bulgaria, Croatia, Greece, Turkey. Traugott-Olsen’s (1992) records from Austria require verification.

Remarks. The DNA barcode of E. dalmatiensis differs 10% from that of the closest haplotype of E. dispunctella. The closest match with DNA barcode is E. disemiella with 7% divergence. On the basis of the barcode divergence, in combination with the morpological differentiation (see diagnosis), E. dalmatiensis is here considered a valid species. See also remarks on E. grandella. E. dalmatiensis is referred to as OTU 11 in Mutanen et al. (2015).
