Molecular data. BIN BOLD: ABV4976 (n = 4, 1 public, 3 from the Altai). The average intraspecific divergence of the barcode region is 0.1% (maximum 0.15%). The nearest neighbour is C. alsinella (Zeller, 1868) with 3.53% p-distance.

Distribution. The Alps ( Switzerland, Austria), Mongolia ( POVOLNÝ 1973, as Caryocolum pr. amaurellum; HUEMER 1988; HUEMER & KARSHOLT 2010), Russia: the Altai Republic, South of Krasnoyarskiy krai, Zabaikalskiy krai ( BIDZILYA et al. 1998, BIDZILYA 2002).

Remark. Caryocolum oculatella was described from the vicinity of Martina in Graubünden in Switzerland where it rarely occurs ( LEPIFORUM 2019) whereas in the Altai mountains it belongs to the abundant species.
