Description. Adult male ( Fig. 12 View Figure 12 ): Length of forewing 9.0– 9.5 mm, wingspan 18–19 mm. Head pale yellow-grey, labial palpi ascending, yellow-grey, second segment with brown patch on outer side, basal segment with long scales on ventral side, terminal segment acute; antenna dark brown, with short cilia ventrally, much shorter in females, scaled dorsally in basal third. Proboscis long and broad, basally scaled. Thorax grey, tegulae and patagia without black spots; mesonotum with five black spots. Legs grey. Forewings grey, with characteristic position of three black spots, two in fold, one at end of cell ( Fig. 12 View Figure 12 ); wing margin without spots; hindwings pale grey, without hair pencil, underside of wings uniformly pale brown, one (♂) or three (♀) brown frenular bristles. Abdomen light brown, without spots, tuft of scales on segment VIII yellow-grey.

short, phallic apparatus with spiral base, manica tubular, enclosing apical tubular phallic apparatus, vesica without cornuti.

Female genitalia ( Fig. 16 View Figure 16 ): Papillae anales long, close together basally, apophyses posteriores short, barely half the length of papillae anales. Segment VIII without apophyses, sterigma with circular lamella antevaginalis and three parallel concave sclerites as lamella postvaginalis. Ostium bursae membranous, antrum weakly sclerotised. Ductus bursae long and thin, coiled. Bursa copulatrix dumbbell-like, without appendix bursae. Signum large, with large and small teeth on inner side.

Male genitalia ( Figs 13–15 View Figure 13 View Figure 14 View Figure 15 ): Tegumen short and broad. Uncus a rounded plate with weak emarginations on lateral margins. Caudal part of gnathos plate-like, distally protruding and slightly upcurved, without thorns; oral part with two e longate lobes each with bundle of long, apical spines. Vinculum short, as a thin half-ring. Labis short, triangular, fused with transtilla. Valva elongate, basal process on inner side lobe-like, membranous, costa thin, cucullus elongate, bent dorso-mediad, apex acute. Juxta Remarks: Within the wursteri group, the new species resembles in the male genitalia E. wursteri Amsel, 1956 described from Jordan and E. infelix Meyrick, 1914 described from “ Mesopotamia ” (= Iraq). The latter species has many spines on the margins of the oral part of the gnathos, whereas these are reduced to an apical bundle in E. stadieana sp. nov. In the female genitalia, the papillae anales are not fused basally as in E. wursteri . Externally, the new species differs from other members of the group by the uniform grey colour of the forewings and by the absence of apical spots at the termen of forewings.

Etymology: The species is named in honour of Dirk Stadie (Eisleben) who collected the type series of the new species.
