Material
4 ♂, 1 ♀, Ukraine, Kiev reg., Mironovka distr., 4 km W Khodorov vill., at light, 24.v.2015, leg. O. Bidzilya. Genitalia slide: O. Bidzilya prep. no. 10/17♂; 11/17♀.
Description
Herewith we provide the description of the hitherto unknown female.
Female
(Fig. 11a). Wingspan 12.1 mm. Head dirty white, neck mottled with brown, segment 2 of labial palpus dirty-white, outer and lower surface light grey mixed with brown-tipped scales, base brown, segment 3 whitish-brown, scape brown with some rare whitish scales, flagellum brown white-ringed in basal half. Thorax, tegulae and forewing covered with grey brown-tipped scales, fold light brown with indistinct black dash on base, three very indistinct black spots surrounded with light brown in cell, cilia light grey black-tipped. Hindwing light grey in basal half and dark grey in distal half, cilia grey.
Female genitalia
(Fig. 12). Segment VIII trapezoidal, slightly narrowed distally; antrum narrow, tubular, of even width, the posterior margins strongly sclerotized, lateral sclerites large, rounded, densely covered with small spines; ductus bursae short and broad, covered with moderately long spines, with two elongated patches of lateral sclerotization; corpus bursae prolonged, signum a rounded plate with two basal short thorn-shaped processes.
Remarks
The sternum VIII of F. djakovica is most similar to that of F. textorella (Chrétien, 1908), but the lateral sclerites are larger. The antrum resembles that of F. incomptella (Herrich-Schäffer, 1854) but lateral sclerotization is poorly developed and the spines are larger. The signum is similar to that of F. tephriditella (Duponchel, 1844) but it is more weakly edged and its lateral process is longer.
Distribution
Romania (Rákosy et al. 2003[1]), Russia (Vladimir and Saratov regions) (Anikin and Piskunov 1996[2]; Piskunov and Uskov 2006[3]). In Ukraine it was known from Lugansk region only (Bidzilya and Budashkin 2004[4]).
Notes
The single female differs from males in more uniformly greyish forewing with poorly expressed spots and in smaller size: the wingspan is 12.1 mm whereas the four males have a wingspan 14.0–17.0 mm. The males are rather variable (Fig. 11b, c): the ground colour of the forewing varies from grey to brown, black spots in cell are usually hardly visible but can be well developed in some specimens. The male genitalia of our specimens (Figs 13, 14) match the holotype except for more weakly developed cornuti in the phallus. This variation has already been mentioned for specimens from the Vladimir region of Russia (Piskunov and Uskov 2006[3]).
