( Figs. 13, 14 View FIGURES 13 – 18 , 23 View FIGURES 19 – 25 , 46–49 View FIGURES 46 – 49 , 59 View FIGURE 59 C, D)

Holotype, ď: Turkey: Anatolia, Konya, salt steppe, 8.IX. 1967 M.& W. Glaser leg. (L. Kaila prep. 4870, SMNK). Paratypes: 14 ď with the same collecting data as in the holotype (L. Kaila prep. 4871, 4872, E. Traugott-Olsen 6501, 6502, Wing prep. nr. 6503 ď, E. Traugott-Olsen, SMNK, MZH, ZMUC).

Diagnosis. Elachista dorinda   is a white species with characteristic ochreous markings as in Figs. 13, 14 View FIGURES 13 – 18 . The male genitalia are characterised by the juxta lobes that are almost as short as in E. antonia   ( Figs. 48, 49 View FIGURES 46 – 49 ). Unlike E. antonia   , the phallus of E. dorinda   contains a large cornutus which most resembles that of E. slivenica   . The cornuti of these species differ by their shape: the cornutus of E. slivenica   is rounded with a very small tooth, that of E. dorinda   is triangular with a larger tooth (cf. Figs. 59 View FIGURE 59 A –D). The juxta lobes of E. slivenica   are much longer and slenderer than in E. dorinda   .

Description. Forewing length 3.7–4.5 mm. Length of labial palpus 1.1–1.2 times diameter of head, white above, ochreous below. Head, neck tuft, scape and pedicel of antenna white, flagellum grey, weakly annulated with paler rings. Scales of tegula and thorax white. Foreleg leaden grey, tibia and tarsal articles distally white, mid- and hindleg pale ochreous, tibia and tarsal articles slightly darker greyish with pale distal rings. Forewing costa basally narrowly dark grey; ground colour white with ochreous markings: broad elongate spot from base to 1 / 4 of wing along fold, irregular triangular spot from dorsal margin to fold, a smaller spot opposite to it in costal side of fold, and narrow zigzagging transverse stripe near apex; fringe scales white, shorter fringe scales distally ochreous grey forming fringe line. Underside of forewing grey, fringe scales white. Hindwing pale grey above and below, with concolorous fringe scales.

Male genitalia. Uncus lobes oval-shaped, 1.5 times longer than broad, distally rounded, with a few setae distolaterally, separated by narrow deep incision. Gnathos elongate oval, broadest medially, twice longer than wide, tapered towards pointed apex. Valva 3.5 – 4 times longer than wide at its widest point in the middle; costa evenly convex medially, distinctly emarginated in distal third; sacculus slightly emarginated at about 1 / 3 length, distally slightly bent, with narrow sclerotised reinforcement, joining cucullus at a right angle; distal margin of cucullus somewhat curved, cucullus a little bent towards costa. Digitate process small, basally narrow, distally blunt and setose. Juxta lobes mesally produced as tongue-shaped, bent lobe with a few setae distally, 1.5 times longer than diameter of median plate of juxta, laterally produced to form sclerotised triangular keel that is joined to valval process. Vinculum small, broad. Phallus slightly over half the length of valva, weakly bent at basal third, tapered towards apex; caecum short, rounded; apex with eversible lobe, shaped as in Figs. 59 View FIGURE 59 C, D; cornutus large triangular sclerotised plate with blunt tooth.

Distribution. Only known from Turkey: Konya.
