Description. ( Figs 6, 7 ). Wingspan 8.0– 8.5 mm. Head with dense tuft of yellowish-orange scales, neck brown. Labial palpus drooping, segment two grey, covered with moderately long grey scales beneath and with long brown scales on apex, segment three brown, inner surface dirty white. Antenna about as long as the length of forewing, scape brown, flagellum dark brown indistinctly ringed. Thorax and tegulae greyish-brown with dark brown scales on anterior margin. Forewing relatively long and narrow, costal margin weakly curved. Ground colour dirty white with three broad transverse light brown fasciae: the first one the narrowest, diffuse, just on base, the second one before middle with uneven outer margin, and the third one at 2/3–3/4 length. Several brown scales between fasciae at mid width. Apex distinctly mottled with brown. Cilia grey irregularly mottled with brown. Hindwing and cilia dark grey. Abdomen greyish-brown, apical segments light grey.

Male genitalia ( Figs 14–14 a). Uncus with paired short triangular projections, medial incision short, triangular. Tegumen somewhat longer than basal breadth, sub-trapezoid, weakly narrowed apically, posteriorly with sparse setae. Gnathos arms small, weakly sclerotized, medial portion small, triangular, anterior margin with broad triangular incision, anterolateral lobes long, serrated anteriorly. Subscaphium well sclerotized, broad. Vinculum a moderately broad ring. Saccus broad and long, weakly constricted before middle, about as long or slightly longer than valva, sub-rectangular, apex rounded, without thorn. Valva broad and short to moderately elongate, subrectangular, apically truncated or narrowed, short weak setae before middle not grouped in clusters. Phallus weakly curved on base, in distal 1/3 narrowed towards pointed apex, two times as long as the length of valva, without cornuti.

Female genitalia ( Figs 17–17 a). Ovipositor rather long and narrow. Papilla analis moderately large, narrowed apically, covered with long sparse setae. Apophyses posteriores narrow, weakly dilated apically, about 4.5 times as long as segment VIII. Segment VIII sub-trapezoid, smooth, weakly wrinkled in distal half. Apophyses anteriores distinctly curved on basal 1/4, about three times shorter and nearly three times broader than apophyses posteriores, connected with band-shaped sclerotization on base. Ostium opening sub-trapezoid, at posterior margin of antevaginal plate. Antrum well sclerotized, rather broad, goblet-shaped. Proximal portion of ductus bursae weakly narrowed, caudal sclerotized portion of ductus bursae 2/3–3/4 length of ductus bursae, distinctly longer than apophyses anteriores. Corpus bursae sub-ovate. Signa forming a large paired nearly connected cluster of long rows of small thorns.

Diagnosis. E. ignorata is characterised externally by a well developed and more black forewing pattern compared to the other species of this group. The male genitalia are characterized by the short uncus projections separated by a short medial incision, the absence of clusters or rows of strong setae before middle of valva and the very long phallus. The female genitalia are recognized by long apophyses anteriores in combination with long sclerotized portion of the ductus bursae, and signa forming large clusters of long rows of small thorns.

Distribution. Greece: Islands Samos and Crete, Turkey (Djanik).

Ecology. Adults were observed from late May to early July up to 920 m altitude.

Etymology. The specific name is derived from Latin “ignoratus” —overlooked, and refers to confusion of this species with other species of E. glaseri -group.
