Scrobipalpa bidzilyai (Povolný, 2001) Figs 25, 26, 82, 83, 134, 135 Euscrobipalpa bidzilyai Povolný 2001: 184. Scrobipalpa bidzilyai (Povolný): Ponomarenko 2008: 4. Type material examined. Holotype of E. bidzilyai ♂, Zabaikalie, Nizhniy Tsasutchey env., sosnovyi bor, 1.vii.1997, at light (O. Bidzilya, I. Kostjuk, O. Kostjuk) (gen. slide Bdz. 45, D. Povolný, remounted by OB) (ZMKU). Material examined. 1 ♂, Russia, S-Buryatia, 51°11-13’N, 106°10-12’E, 700 m, Hamar-Daban Mts, Murtoi river, Gusinoe Ozero vill. 6 km NW, forest steppe, 22.vi.2002 (Nupponen) (gen. slide 196/19, OB) (Barcode TLMF Lep 28319); 1 ♀, same data as for preceding (gen. slide 197/19, OB) (Barcode TLMF Lep 28322); 1 ♀, Russia, SBuryatia, 51°11-13’N, 106°10-12’E, 700 m, Hamar-Daban Mts, Murtoi river, Gusinoe Ozero vill. 6 km NW, forest steppe, 19.vi.2002 (Nupponen) (gen. slide 143/21, OB) (all NUPP); 2 ♂, Russia, Buryatia, Selenga distr., Taiozhnyi vill., 28.vii.1994, at light (Ustjuzhanin) (gen. slide 200/15, OB); 1 ♂, Zabaikalie, Chita region, Kyra env., 14,16, 17. vii. 1997, 900 m, at light (O. Bidzilya, I. Kostjuk, O. Kostjuk) (gen. slide Bdz. 7, D. Povolný, remounted by OB; 193/07, OB) (all ZNKU). Diagnosis. Scrobipalpa chitensis (Figs 22–24) and S. bidzilyai (Figs 25, 26) are very similar to each other and cannot be separated unambiguously externally. However, S. bidzilyai is larger in wingspan (10.2–10.5 mm), whereas the wingspan of S. chitensis is 8.8–9.0 mm. The male genitalia are more diagnostic: in S. chitensis (Figs 80, and the vincular process is shorter, broader and weaker, curved outwardly; posteromedial emargination of vinculum without inner hump (with distinct hump in S. bidzilyai). Additionally, the genitalia capsule of S. bidzilyai is larger (Figs 82, 83). The female genitalia of S. bidzilyai are nearly indistinguishable from those of S. chitensis. However, we found a small difference in the length of the ductus bursae that is 3–4 times the length of the apophyses anteriores in S. bidzilyai and 2–2.5 times in S. chitensis. Additionally, the ventromedial depression in S. bidzilyai is broader, and the subgenital plate bears a medial fold that is absent in S. chitensis. The total length of the female genitalia of S. bidzilyai is 1.5–2 times longer than that of the female genitalia of S. chitensis. Female genitalia (Figs 134, 135). Papillae anales subovate, covered with short setae; apophyses posteriores 4 times as long as apophyses anteriores; segment VIII about as broad as long, sternum VIII densely covered with microspines, subgenital plates 1/4 width of sternum VIII, parallel-sided, with medial folds, lobes of ventromedial depression broad, rounded, separated by triangular incision anteromedially, not extending beyond anterior margin of sternum VIII; apophyses anteriores as long as segment VIII and 3–4 times length of ductus bursae; ductus bursae moderately broad, of even width except narrowed posterior portion; corpus bursae rounded, 1/3 length of ductus bursae; signum with large, subtriangular basal plate and straight or weakly curved acute process directed anteriorly. Molecular data. BIN: BOLD:AEC6545. The intraspecific average distance of the barcode region is 1.17 (n=2). The minimum distance to the nearest neighbour, S. reiprichi (BIN: BOLD:ACY6331), is 2.4 %. Distribution. Russia: Buryatia, Zabaikalskiy kraі (Povolný 2001: 184; Bidzilya 2009: 6); China: Hebei (Li & Bidzilya 2019: 128). Remark 1. Euscrobipalpa bidzilyai was described from one male and one female collected in the vicinity of Nizhniy Tsasutchei (holotype) and Kyra (paratype) villages of Zabaikalskiy krai in Russia. The female genitalia of S. bidzilya illustrated by Povolný (2002: 72, fig. 727) are in fact those of S. ferruginosa (Povolný, 2001). For the details see below under the latter species. Here we describe the female genitalia of S. bidzilyai for the first time. Remark 2. Scrobipalpa caryocoloides Povolný, 1977 was described from the holotype female collected in Japan (Hokkaido, Sapporo). The species looks indistinguishable superficially from S. bidzilyai and S. chitensis. The female genitalia of the holotype are very similar to those of S. bidzilyai. However, we prefer to treat S. bidzilyai and S. caryocoloides as separate species until more material from Japan including the unknown male becomes available.
