Figs. 3i–p , 6a , 13 , 27 .

Description. Male. Forewing length 15–16 mm. Wings dark with white fringes and wide light border along the marginal and costal (fore wing) borders. Central cell with white veins. Underside with greatly reduced postdiscal spots. Female. Forewing length 15–16 mm. Upperside white. Underside with strongly reduced eyespots. Forewing underside in its angle with expressed lighting.

Diagnosis. This new subspecies (as far as kobdoensis) is an intermediate taxon between the groups glacialis and biocellata . Specimen are very small, males with wide white bordering on the wing upperside (the bordering often extends to the costal area), in the central cell white veins are visible (as in the previous subspecies, which is larger and with larger postdiscal eyespots). Postdiscal eyespots on the underside are reduced, but the quite large cubital spots on the forewings can remain; they are always without white centers. Underside always with contrasting bright veins. Female has brightening on the forewing underside in the anal angle.

Etymology. New subspecies named after Artur Yakovlev, son of the third author, who helped to collect a part of the type series.
