Adela orientella Staudinger, 1870 sp. rev. (figs. 7, 8) Adela orientella Staudinger 1870, n° 723, pl. III, fig. 6. Adela getica Mann, 1871. Material examined. 1♂, Grecia, Kreta, Melampes 1, 1 km NNE, 35°08'14"N 24°39'20"E, 275 m: 28.IV.2022, leg. Huemer P.: prep. mic. 2162 TG, RCPH; 1♀, idem, DNA barcode TMLF Lep 34745: prep. mic. 2161TG, RCPH. Supplementary material: 1 specimen, Grecia, Peloponneso, Arkadia, Dara, 21.V.1977, D. Gianasso leg. det. W. Sauter, GBRC. Adult (n 3); head with dark labial palps with long black hair-like scales above and below, head covered with long black and yellow hair-like scales in variable percentages; black antennae with white distal tip, about twice the length of the forewings, in the female slightly longer than the forewings; brown thorax with bronze and golden reflections; legs covered with black and white scales, tarsal formula 0-2-4; forewing length 4.4–5.5 mm, brown background color with golden bronze and purple reflections, white median band orthogonal to the costa, straight, a small white spot on the costa between the median band and the tip of the wing, dark brown fringes; hindwings brown with purple reflections, brown fringes. Genitalia ♂ (pl. I f, g, l); uncus extremity with double hump, broad and flat; tegumen well sclerotised; vinculum rounded and broad posteriorly; valves subtriangular, with rounded distal end; sclerotized transtilla with median protrusion, lateral arms approximately equal; aedeagus with truncated base, sinuous, with horns at the distal end for ¼ of the total length; juxta approximately ½ length of the aedeagus with a sagittate end pointed. Genitalia ♀ (pl. I h, i): ovipositor with acuminate end in lateral view, bursa with signa, VII tergite and VII sternite slightly sclerotized sub-triangular. Biology: adults are in flight in April and prefer white flowers of Leucanthemum, Bellis and Anthemis (Bryner, 2020). Habitat: Mediterranean maquis. Distribution: Greece incl. islands, Cyprus, Romania. Diagnostic Characters: Adela paludicolella is distinguished from Adela orientella by the forewings, which have a white median band curved towards the end of the wing (fig. 3, 4, 5, 6), by the shape of the valves of the uncus and transtilla (pl. I a, b, f, l), and in the female by the absence of signa in the corpus bursa (pl. I d, h). Finally, both species clearly differ in the DNA barcodes (Fig. 11).
