Description. Male. Forewing length 19–20 mm, wings are dark with light and bright wide border and fringes. On the hindwing upperside, the discal cell is highlighted on veins by thin light stripes. Forewing underside with cubital spots much larger than other postdiscal spots (very different size). Hindwing upperside has well pronounced spots of almost equal size. The light pattern on wings’ upperside is well developed. Female. Forewing length 20 mm, wings’ upperside light yellow, light pattern on the wings’ underside well developed, wings with “colourful” appearance.

Diagnosis. This subspecies is much larger than ssp. glacialis O.B.-H. and other related subspecies. White edging on the wings’ upperside is rather wide. Discal cell on hindwing highlighted by thin light stripes. Apical bordering of the central cell in the wings often delineated by bright color. Cubital eyespots on the forewing underside are much larger than the others, all postdiscal spots are without white centers. Light bordering of veins is very clear. Upperside pattern is very mottled.
