Description. Male. Forewing length 18–19 mm. Forewing relatively wide with rounded apex. Wing upperside dark-brown with thin (about 0.5 mm) and bright fringes. The entire area of wings covered by suffusion of light scales. Eyespots on wings’ underside are very small, on the forewing they are slightly centered by white color; on hindwing underside these eyespots are mostly reduced. Wings’ underside with well visible suffusion of light scales. Central part of hindwing underside with fuzzy yellow pattern of wide strokes between veins, which are highlighted by wide dull white strokes. Female. Forewing length 17–18 mm, wings white or whiteyellowish, the wings pattern is same as in the male.

Diagnosis. It differs from T. nervosa nervosa , the closely related subspecies, by the following features: postdiscal spots are almost always visible (though much reduced); cubital spots on the forewing underside are slightly larger than the other spots, in females the spots are not visible on the upper surface; white edging on the wings’ upperside is very narrow; white veins on the underside are expressed very well, but the drawing is not mottled; on both wings’ surfaces a strong suffusion of light scales is expressed.

Etymology. New subspecies named after V. Brinikh, a well known Russian ecologist.
