Scrobipalpa cinerosella Bidzilya 2009: 9.
Type material examined. Holotype of S. cinerosella ♂, Russia, Altai, Ongudai distr., Bolshoi Yaloman, 700 m, 2.viii.2001, svet, A. Bidzilya (gen. slide 194/08, OB) (ZMKU). Paratypes: 1 ♂, Altai, Ongudai distr., Tchuya river bank in 15 from Iodro vill., 6.viii.2000 (Bidzilya) (gen. prep.); 1 ♂, Altai, Kosh-Agatch distr., Dzhazator env., 1500 m, 28.vii.2001, at light (Bidzilya); 1 ♂, Tuva, 15 km S of Kyzyl, 14–15.vi.2001, 1000 m, steppe (Ustjuzhanin) (gen. slide 195/08, OB) (all ZMKU).
Other material examined. 2 ♂, 1 ♀, Russia, Altai Republic, Belyashi (Dzhazator) env. (25 km NW), confluence of Argut and Karagem rivers, 49°51′56″N, 87°10′22″E, rocky steppe, 1400 m, 27–28.vii.2017 (Šumpich) (gen. slides 240/ 20♀, 298/ 21♂, OB) (Barcode NMPC-LEP-0400) (NMPC).
Diagnosis. The species is characterised superficially by the forewing indistinctly divided into a grey costal part and light brown dorsal part. Scrobipalpa inexplictata sp. nov. is similar, but the grey pattern is more distinct on the dorsal part. Scrobipalpa perfecta (Povolný, 1996) has a broader grey costal pattrern that extends to the fold; S. superba (Povolný, 1996) comb. nov. has a narrower forewing. The male genitalia are distinguished by the elongate cucullus and tegumen, short sacculus and straight vincular process. Scrobipalpa cinerea (Povolný, 1996) comb. nov. is very similar but the sacculus is narrower than the adjacent portion of the cucullus (broader in S. cinerosella, Fig. 98), and the vincular process is broader in S. cinerosella. The smooth subgenital plate with a sclerotised pattern along the medial margins and the broad ductus bursae are characteristic of the female genitalia. Scrobipalpa zaitzevi is similar, but differs in the broader lobes of the ventromedial depression and sternum VIII with a weakly sclerotised anterior edge (strongly sclerotised in S. cinerosella).
Female genitalia (Fig. 145). Papillae anales subovate, sparsely covered with short setae; apophyses posteriores about 4 times as long as apophyses anteriores; segment VIII nearly as long as broad, sternum VIII with deep rounded posteromedial emargination, anterior margin distinctly sclerotised, subgenital plates 1/3 width of segment VIII, smooth, weakly sclerotised in lateral part and with distinct sclerotised pattern in medial part, anteromedially strongly edged, ventromedial depression covered with fine microtrichia in anterior part, lobes of ventromedial depression slender, separated anteriorly with large, deep triangular incision with distinctly edged margins, not extending beyond anterior margin of sternum VIII; apophyses anteriores distinctly longer than segment VIII, straight; colliculum narrow, ring-shaped; ductus bursae gradually broadened towards corpus bursae, corpus bursae small, rounded, signum at right side of ductus bursae before entrance to corpus bursae, basal plate of signum stout, distal hook slender, short, with several basal teeth, gradually curved.
Biology. Adults have been collected in a rocky steppe biotope in late July at an altitude of 1400 m.
Molecular data. BIN: BOLD:ADR6357. Intraspecific DNA barcode variation unknown. The minimum distance to the nearest neighbour, S. marmorella (BIN: BOLD:AEK6015), is 3.86%.
Distribution. Russia: Altai, Tuva.
Remark 1. Scrobipalpa cinerosella is very similar externally and in the male genitalia to S. cinerea (see above under Diagnosis), but the females are quite different. We hesitate to synonymize these species until more extensive material of both species becomes available, and DNA study confirms the current association of the male sex to the corresponding female.
Remark 2. The female genitalia of S. cinerosella are described here for the first time.
