( TLMF); 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, 1 (Barcode KLM Lep 06375), C.Wieser leg. ( LMK); Belyashi env. (56 km SE), 49°39′45″N, 88°14′28″E, Dzhazator valley, mountain meadows near Tara river, 2300 m, 25.–26.vii.2017, 17 (Barcode NMPC-LEP-0370), J. Šumpich leg.

Molecular data. BIN BOLD: AAE9479 (n = 10, 5 public, 5 from the Altai). The average intraspecific divergence of the barcode region is 0.6% (maximum 1.31%). The nearest neighbour is C. schleichi (Christoph, 1872) with 2.25% p-distance.

Distribution. Europe: southern Scandinavia, the Baltic countries, Macedonia, Mongolia, Russia: the Altai Republic, Zabaikalskiy krai, Middle Amur ( HUEMER & KARSHOLT 2010, PONOMARENKO 2016, HUEMER et al. 2017).

Remark. Until recently, Caryocolum arenariella was treated as a subspecies of C. schleichi (Christoph, 1872) . Based on a recent study it was re-elevated to the species level ( AARVIK et al. 2017).
