Erebia kefersteini Eversmann, 1851.

This species usually have black submarginal dots (corresponding to the ocelli in most Satyrids), as showh on the neighbouring picture, but individuals occur without them, as shown here. Interestingly, there is another very close species, Erebia kindermanni Staudinger, 1881 (also shown on this page) ranging in Central and SW Altai only where it (but in an intricate pattern of localities) replaces E. kefersteini, in which individuals without dots are more frequent than with dots. (Some butterly lovers in Russia believe the dot presence is a character of distinction between these species, that is not correct).
