Diagnosis. The new species is characterised externally by the yellowish brown forewing with a distinct grey suffusion along the veins and costal margin, and diffuse pale angulate subapical fascia. The latter character separates S. krasnogorka sp. nov. from the externally similar S. inferna, S. altubura sp. nov. and S. mongolica. The slender elongate tegumen and uncus in combination with the long and broad vincular process, and short saccus are characteristic of the male genitalia. The female genitalia are distinguished by sternum VIII being entirely covered with foam sclerotisation, broad lobes of the ventromedial depression which far project anteriorly, the broad ductus bursae and slender signum. Scrobipalpa spumata has very similar male and female genitalia (Figs 106, 152), but differs in the broader, less narrowed apically vincular process in the male genitalia and less developed foam scales tipped with dark grey or brown, frons paler, light grey to white, labial palpus upcurved, white densely mixed with greyish black, without distinct dark rings, palpomere 2 with inner surface lighter, off-white, upperside with brush of modified scales, palpomere 3 about 1/2 length and width of palpomere 3, acute, white apex, scape brown with a few white scales, flagellomeres brown ringed with white. Forewing ground colour yellow to light brown, veins and costal margin with distinct grey irroration. Hindwing and cilia grey.
Variation. Specimens look darker or lighter depending on the extent of grey irroration; diffuse ochreous-brown spots in the cell are present in the female paratypes.
Male genitalia (Figs 104, 105). Uncus subrectangular, twice as long as broad, posterior margin straight; gnathos slender, weakly curved; culcitula elongate, well developed; tegumen slender, elongate, with indistinct transition to uncus, anteromedial emargination broad, extending to 1/3 length of tegumen; cucullus slender, weakly curved, slightly expanded apically, extending to top of uncus; sacculus 1/4–1/3 length of cucullus, of even width, weakly constricted before middle, inner margin straight, outer margin bent inwards at 2/3, tip inwardly turned; vinculum twice as broad as long, posterior margin with broad V-shaped emargination, vincular process stout, twice as broad at base as sacculus, narrowed posteriorly, with distinct pointed outwardly curved tip, not extending to top of sacculus; saccus slender, gradually narrowed apically, extending to or slightly extending beyond top of pedunculus; distal portion of phallus straight, of about even width, as long as strongly inflated caecum, apical arm narrow, placed at right angles to phallus.
Female genitalia (Fig. 151). Papillae anales subovate, covered with short setae; apophyses posteriores four times as long as apophyses anteriores; segment VIII slightly broader than long, posterior margin of sternum VIII as broad as long; subgenital plates parallel-sided, 1/3 width of sternum VIII, densely covered with foam sculpture from base of apophyses anteriores to 3/4 length; ventromedial depression covered with fine microtrichia, laterally broadly folded, lobes of ventromedial depression distinctly separated from subgenital plates, rounded and outwardly curved anteriorly, extending beyond anterior edge of sternum VIII, with triangular anteromedial gap, densely covered with foam sculpure; apophyses anteriores as long as segment VIII, straight; ductus bursae broad, of even width except for narrow posterior 1/6, colliculum short; corpus bursae clearly distinguished from ductus bursae, rounded, signum on right side near entrance of corpus bursae, basal plate of signum small, distal hook narrow, gradually curved, pointed, with three teeth at base.
Biology. Adults have been collected in late June in a rocky steppe biotope between 1400 to 1870 m elevation.
Molecular data. BIN: BOLD:AEK7325. The intraspecific average distance of the barcode region is 0.2% (n=6). The minimum distance to the nearest neighbour, S. griseofusella (Toll, 1947) (BIN: BOLD:AAW4673), is 6.17% (p-dist) (Fig. 6).
Distribution. Russia: Altai.
Etymology. The specific name is derived from type locality—Krasnaya Gorka in Kosh-Agatch district in the Altai Mountains of Russia.
