Caryocolum petryi (Hofmann, 1899) ( Fig. 6 )

Records. HUEMER et al. (2017).

Material examined. RUSSIA: ALTAI REPUBLIC: Kosh-Agach district, 10 km NE of Kosh-Agach, Kurai Mountains Range, Tabozhok valley, 2.100 m a.s.l., 50°4′32.36″N, 88°43′41.83″E, 2.–4.viii.2016, 2 (Barcode KLM Lep 06372, KLM Lep 06379), C. Wieser leg. ( KLM); 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, 6 5 ♀♀ (Barcode NMPC-LEP-0363, NMPC-LEP-0364, NMPC-LEP-0365, NMPC-LEP-0366), J. Šumpich leg. ( NMPC).

Molecular data. BIN BOLD: AAM 0549 (n = 14, 8 public, 6 from Altai). The average intraspecific divergence of the barcode region is 0.15% (maximum 0.64%). The nearest neighbour is C. baischi Huemer & Karsholt, 2010 with 3.37% p-distance.

Distribution. Palaearctic. In Russia it is known only from the Altai Republic and Zabaikalskiy krai ( BIDZILYA 2005, HUEMER et al. 2017). Material published by POVOLNÝ (1973) from Mongolia as C. pr. repentellum (= C. repentis) actually belongs to C. petryi .

Remark. Material from the Altai Mts. resembles rather the nominotypical population from Germany (Thuringia) than the darker and smaller specimens from Sweden (Öland) that were described as the subspecies benanderi (Hering, 1933). Similar dark, but larger specimens also occur in the Baltic countries and SE Poland, and furthermore in higher regions of the Alps.
