Description. ( Figs 1–3 View FIGURES 1 – 10 ). Wingspan 7.0– 9.8 mm. Head with dense tuft of dirty-white scales, neck brown, laterally with several brown scales on base of scape. Labial palpus moderately long, straight, segment two nearly as long as segment three, creamy with long brown scales on apex and brush of shorter whitish scales beneath, segment 3 brown with dirty-white top, inner surface white. Antenna slightly longer than forewing, greyish-brown, not ringed, scape slightly darker than flagellum. Thorax and tegulae dirty white to light grey, mottled with brown anteriorly. Forewing relatively long and narrow, costal margin weakly curved. Ground colour dirty white to creamy with three transverse light brown fasciae: the first one (sometimes strongly reduced) just on base weakly narrowed towards dorsal margin, 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 mottled with brown. Cilia grey, irregularly mottled with brown. Hindwing dark grey. Cilia grey. Abdomen brown, last segments light grey.

Male genitalia ( Fig. 11 View FIGURES 11 – 14 ). Uncus with paired comparatively long thorn-shaped projections, medial incision broad, deep, sub-rectangular. Tegumen about as long as broad on base, sub-trapezoid, posterolaterally with several rare setae. Gnathos arms moderately narrow, medial portion small, sub-triangular, anterior margin with deep triangular incision, anterolateral lobes long, branchial-shaped. Subscaphium weakly sclerotized. Vinculum broad. Saccus broad, about 2/3 length of valva, sub-rectangular, apex rounded, without thorn. Valva rather long and narrow, sub-rectangular, apically obliquely truncated, with tuft of strong pointed setae before middle. Phallus weakly curved at 1/4, narrowed towards pointed apex, 1.4–1.6 times longer than the length of valva, without cornuti.

Female genitalia ( Fig. 15 View FIGURES 15 – 18 ). Ovipositor rather long and narrow. Papilla analis moderately large, narrowed apically, covered with long rare setae. Apophyses posteriores narrow, weakly dilated apically, about 4.5 times longer than segment VIII. Segment VIII sub-trapezoid, smooth, weakly wrinkled above ostium. Apophyses anteriores weakly curved, more than three times shorter and nearly three times broader than apophyses posteriores, connected with band-shaped sclerotization on base. Ostium opening semi-ovate, at posterior margin of antevaginal plate. Antrum weakly sclerotized, goblet-shaped. Proximal portion of ductus bursae narrow, caudal sclerotized portion of ductus bursae about 3/4 length of ductus bursae, distinctly longer than apophyses anteriores. Corpus bursae small, rounded. Signa forming a single cluster of small thorns.

Diagnosis. E. glaseri resembles externally E. saxatilis sp. n., but it is distinctly larger and the antennae are not ringed. The male genitalia differ from those of the last species in the longer and narrower uncus projections, distinctly longer saccus, larger and stronger tuft of setae on valva and distinctly longer and narrower phallus. The female genitalia are similar to those of E. ignorata sp. n. and E. armatum , but differ from the former in the narrower and longer antrum and presence of wrinkles above the ostium bursae. For the differences of the female genitalia of E. glaseri to similar female genitalia of E. armatum , see the diagnosis and the description of female genitalia of the latter species.

Distribution. North-East Spain ( Petersen 1967) and South-West France ( Nel & Varenne 2004).

Remarks. E. glaseri was described from four males (including holotype) and two females collected in North- East Spain (Catalonia, Gerona, Port Bou) and five females from continental Greece (Peloponnese, Zachlorou, Kalavryta) ( Petersen 1967). The examination of the type series shows, that the female paratypes from Greece are not conspecific with the females from Spain.

The examination of male specimens from the series from Greece (Peloponnese, Zachlorou, Kalavryta, leg. J. Klimesch) shows that the entire series belongs to Eudarcia armatum , hitherto known only as a male holotype from Greece (Lakonia). The detailed examination of additional specimens from some Greece islands and from Turkey, previously also determined as glaseri , shows that these specimens belong to an undescribed species. Its description under the name ignorata sp. n. is given below.

Here below we list the records with references, in which specimens were erroneously identified as glaseri .

The females (part of paratypes) from Kalavryta ( Petersen 1967: 359, Fig. 2 View FIGURES 1 – 10 ), the female from the same location ( Zagulajev 1979: 381, Fig. 321), the female from Kalavryta and Laconia ( Petersen & Gaedike 1983: 285), and the illustrations on plate 3: Fig. 105b (adult) and Fig. 105 (female genitalia) in Gaedike (2015) belong to the hitherto unknown females of E. armatum .

The records ( Petersen & Gaedike 1983: 285; Gaedike 1997: 100 [female instead of male]; 2015: 107) from Crete (male and female) and from Turkey (female) belongs to E. ignorata sp. n.

The record from Crimea ( Gaedike 2015: 107) belongs to E. saxatilis sp. n.

The record from Georgia (Abkhazia) ( Petersen & Gaedike 1983: 285; Gaedike 2015: 107) belongs to E. abchasicum .

Biology. The adults have been collected in late May and from mid-June to early July in Spain ( Petersen 1967; Gaedike 2015); in mid July at an altitude of 470 m near the sea coast in France ( Nel &Varenne 2004).
