Oeneis aktashi ona Korshunov, 1996

Specimens: 14\Sayanskiy Pass, 4♂, 4♀.

Remarks: Sayanskiy Pass is the type locality of this species, so the specimens collected were topotypes.

Observations: A strictly highland species which occurred only on screes on slopes above the pass, with average vegetation cover varying from ca 50% to zero. They flew very fast and for long distances but readily landed exclusively on flat shale stones of which those screes were composed. There they sat mostly in a vertical position, but when the sun hid behind a cloud they almost laid on one side ( Fig. 14 ), seemingly to be oriented perpendicular to the sun when it reappears. But if the sun did not reappear soon, they, keeping the same laying position, crawled towards a stone margin and hid between stones. A copulating pair was noticed on top of a local relief maximum.
