Diagnosis. E. arenbergeri is a large species, white or pale yellow, often with ochreous dusting forming irregular, longitudinal stripes. The male genitalia are characteristic, with large, distolaterally pointed uncus lobes, as in species of the E. dispilella complex (cf. Traugott-Olsen 1990, Kaila et al. 2015). Unlike them, it has no cornuti. In addition, the corpus bursae contains no signum, and the ductus bursae is gradually widened anteriorly.

Biology. Unknown.

Distribution. Tunisia, Morocco.

Remarks. E. arenbergeri is referred to as OTU 6 in Mutanen et al. (2015).
