Caryocolum pullatella (Tengstrom, 1848) Records. HUEMER et al. (2017). Material examined. RUSSIA: ALTAI REPUBLIC: Teletskoe lake,Artybash biol. St, 18.–22.viii.1982, 7 3 ♀♀, Mikkola leg. (FMNH); Kuragan valley, 15 km S Katanda, 1200 m a.s.l., taiga, 23–25.vii.1983, 1 (GU 94/481, P.Huemer),Mikkola,Hippe & Jalava leg. (FMNH); Katun valley, 700 m a.s.l., near Ust-Sema village, 51°40′N 85°45′E, 23.vi.2000, 3 1♀♀ (gen. slide 249/ 19 ♀, O. Bidzilya), T. & K. Nupponen leg.(NUPP); Ulagan district, 11 km NNW of Aktash, 1.900 m a.s.l., 50°24′49.22″N, 87°34′21.42″E, 28.–30.vii.2016, 2, (Barcode TLMF Lep 20249, TLMF Lep 20250), P. Huemer & B. Wiesmair leg. (TLMF); 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, 1 (Barcode NMPC-LEP-0374), J. Šumpich leg. (NMPC); Ust-Kan env. (6 km E), 50°56′05″N, 84°51′17″, grassy steppe, meadow, 1100 m a.s.l., 12.vii.2014, 3 (gen. slide 195/18, O. Bidzilya), J. Šumpich leg. (NMPC). Molecular data. BIN BOLD:AAC1599 (n = 37, 33 public, 3 from the Altai). The average intraspecific divergence of the barcode region is 0.25% (maximum 0.72%). However, several other BINs were assigned to the species C. pullatella: AAC1598 (southern and central Europe), AAC1597 (Canada), AAH6281 (Canada), AAH4284 (Canada, USA), ACI5465 (USA), which can indicate cryptic diversity there. The Altai specimens are clustered together with North-European records (Norway, Finland). Distribution. Holarctic according to the current concept. In Russia it was recorded from the European part to Zabaikalskiy krai in the east (PONOMARENKO 2008). Remark. Caryocolum pullatella was described from Finland (cf. HUEMER 1988). Based on the barcode data, the Altai specimens belong to true C. pullatella, with a distribution possibly restricted from northern Europe to southern Siberia, whereas other populations probably represent cryptic species which should be revised (see also NAZARI & LANDRY 2012).
