Caryocolum cassella (Walker, 1864) ( Fig. 2 )

Records. BIDZILYA (2009).

Material examined. RUSSIA: ALTAI REPUBLIC: Teletskoe lake,Artybash Biol. St., 18.–22.viii.1982, 1, Mikkola leg. ( FMNH); Katun valley, 15 km S of Katanda, 1200 m a.s.l., taiga, 2.–25.vii.1983, 13 2 ♀♀, K. Mikkola, H. Hippa & J. Jalava leg. ( FMNH); Ust’-Sema district, Kamlak env., 6.vii.2001, 1 ♀, at light, O. Bidzilya leg. ( ZMKU); Aktash vill., 50°19′12″N, 87°36′00″E, 1400 m a.s.l., grassy steppe, rocks, 11.vii.2014, 1, J. Šumpich leg. ( NMPC); Belyashi env. (56 km SE), 49°39′45″N,

region of the first cluster is 0.06% (maximum 0.17%), and 0.32% (maximum 0.48%) of the second one. The average divergence between these clusters is 1.77%.

Distribution. From Europe to Japan, Korea and China ( HUEMER & KARSHOLT 2010).

88°14′28″E, Dzhazator valley, mountain meadows near Tara river, 2300 m, 25.–26.vii.2017, 6 3 ♀♀ (Barcode NMPC-LEP-0371, Barcode NMPC-LEP-0379), J. Šumpich leg. (NMPC); 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, 4 1 ♀ (Barcode NMPC-LEP-0372, NMPC-LEP-0380), J. Šumpich leg. (NMPC).

Molecular data. BIN BOLD: ACX4318 (n = 49, 34 public, 4 from the Altai), AAM7959 (n = 26, 26 public, 0 from the Altai). The average intraspecific divergence of the barcode region of the first cluster is 0.43% (maximum 1.16%), and 0.41% (maximum 0.81%) of the second one. Whereas the second cluster (BIN AAM7959) comprises exclusively records from Canada, in the first cluster (BIN ACX4318) records from Canada and the whole Palaearctic are merged. The average distance between these clusters is 1.37%.

Distribution. Holarctic. In Europe as well as in Russia predominantly in the mountains ( BIDZILYA 2002, 2009; HUEMER & KARSHOLT 2010).

Remark. Large material from the Holarctic Region was examined, and no distinct differences in habitus or genitalia were found ( HUEMER 1988, HUEMER & KARSHOLT 2010, NA- ZARI & LANDRY 2012).We therefore consider both genetic clusters conspecific.
