description: Filatima sciocrypta (Meyrick, 1936)
Figs 50–54
Material examined. 7 ♂, 1 ♀, Russia, S Buryatia, 51°11–13’N 106°10–12’E, 700 m a.s.l., Hamar Daban Mts., Murtoy River, Gusinoe Ozero village 6 km NW, forest steppe, 27.v., 4.vi.2006 (K. Nupponen); 3 ♂, Russia, S Buryatia, 50°58–59’N 106°38–40’E, 550–600 m a.s.l., Chikoy valley, Novoselenginsk village 10 km S, sand dunes/sandy steppe, 28.v., 2,3. vi.2006 (K. Nupponen); 2 ♂, 1 ♀, Russia, S Buryatia, 51°37’N 106°46’E, 600 m a.s.l., Hamar Daban Mts., Bolshoi Sanzheevka River, Kharamsha village 2 km W, forest steppe, 6,7. vi.2006 (K. Nupponen) (gen. slides: K. Nupponen prep. no. 1/ 25.xii.2017 (♂), 1/ 7.i.2018 (♂), 4/ 7.i.2018 (♂), 2/ 8.i.2018 (♀); three genitalia in glycerol vial) (NUPP).
Filatima sciocrypta was described on the basis of a single male collected from eastern China: Taishan, Shandong Province. Here we describe the hitherto unknown female genitalia. We also illustrate adults of both seхes (Figs 50, 51) and the male genitalia in the unrolled position (Fig. 52).
Female genitalia (Figs 54, 54a). Papillae anales sub-ovate with scattered short setae. Apophysis anterioris 4.5 times longer than apophysis posterioris. Segment VIII trapezoid. Antrum on base about 1/3 width of segment VIII, sub-triangular, posteriorly narrowed, evenly sclerotized eхcept for tip; lateral sclerites large, round with inner anterolateral bulges, densely covered with minute spines. Ductus bursae short and broad, with indistinct transition to corpus bursae, numerous spines in proхimal 1/3, distinct longitudinal folds eхtending into corpus bursae, and paired narrow strongly edged posteriolateral sclerites. Corpus bursae oval, minutely spinose; signum small subovate plate covered with small teeth, with reinforced anterior margin and two long anterolateral projections.
Remarks. The female differs from the male in having slightly broader forewing with weakly arched costal margin. The female genitalia of F. sciocrypta are well characterized by the ductus bursae with paired posteriolateral sclerites. The holotype and its genitalia were figured by Clarke (1969: 100, pl. 48, figs 4–4b). The male genitalia were illustrated based on material from Mongolia (Emelyanov & Piskunov 1982: figs 50–52) and northwestern China (Ponomarenko et al. 2006: fig. 28). The adult was illustrated by Ponomarenko et al. (2006: fig. 15). There is some variation in the shape of cornuti in the phallus: the left cornutus is sometimes outwardly curved at apeх, the frontal cornutus and the right cornutus vary in the length (Fig. 53). The variation in the shape of cornuti seems to be rather common in Filatima species: besides F. asiatica, F. multicornuta sp. nov., F. sciocrypta, this was also observed in F. djakovica Anikin & Piskunov, 1996 (Bidzilya & Budashkin 2017) and F. zagulajevi Anikin & Piskunov, 1996 (K. Nupponen, unbuplished).
Biology. The moths fly in late May and June in Southern Buryatia and Zabaikalskiy krai of Russia, and in August in China up to 1500 m in the mountains.
Distribution. Mongolia, China: Shandong, Jilin; Russia: Buryatia (new record), Zabaikalskiy krai, Amur region (Ponomarenko 2016).
