Molecular data. BIN: BOLD:AEC7224. The intraspecific average distance of the barcode region is 0.16% (n=2). The minimum distance to the nearest neighbour, S. obsoletella (Fischer von Röslerstamm, 1841) (BIN: BOLD:AAF1200), is 5.45%. Female genitalia (Fig. 136). Papillae anales subtriangular, densely covered with short setae; apophyses posteriores four times as long as apophyses anteriores; segment VIII about as broad as long, posterior margin of sternum VIII with broad triangular medial emargination extending anteriorly to about half length of segment VIII, subgenital plates subrectangular, weakly sclerotised along outer margins, with foam sculpture along inner margins from base of apophyses anteriores to mid-length posteriorly, lobes of ventromedial depression subovate with weakly pointed anteromedial corners, with deep triangular anteromedial emargination, densely covered with foam sculpture, not extending beyond posterior margin of sternum VIII; apophyses anteriores straight, as long as length of segment VIII; colliculum narrow, ductus bursae long and narrow, corpus bursae egg-shaped, signum stout, weakly curved, inner margin serrate to half. Distribution. Russia : Buryatia (new record), Zabaikalskiy krai ( Povolný 2001: 197 ); China (new record). Remark 1. Euscrobipalpa tenebrata was described from a single male ( Fig. 27 ) collected in the vicinity of Chita, Zabaikalskiy krai of Russia . The studied specimens from Buryatia and Zabaikalskiy krai match superficially and in the male genitalia the holotype of S. tenebrata . All examined specimens show variations in the length of the uncus and width of the saccus ( Figs 84 –86). However, DNA barcodes clearly justify them as one species with an interspecific variation of 0.16%. Remark 2. Scrobipalpa tenebrata is probably conspecific with S. felixi Povolný, 1978 . The latter was described from a single male from Mongolia . However, we hesitate to establish this synonymy until the holotype of S. felixi is examined. The female genitalia of S. tenebrata are characterised by the subgenital plate membranous along the outer margin in combination with foamy sculptured lobes of the ventromedial depression and stout signum. Scrobipalpa zaitzevi Piskunov, 1990 has a somewhat similar segment VIII with a partially membranous subgenital plate, but differs in the narrower and weaker covered with foam sculpture lobes of the ventromedial depression, longer apophyses anteriores that exceed the length of segment VIII (not exceeded in S. tenebrata ), broader ductus bursae and smaller, rounded rather than egg-shaped corpus bursae as well as a shorter signum (Figs 137, 138). Remark 3. Here we describe the female genitalia of S. tenebrata for the first time.
