Hi Heiner!
I have found Proterebia afra this year in Ukraine.
In Crimea there are two subspecies of this genus - in rest of Ukraina and in steppe part of Crimea - P. afra afra (Fabricius, 1787) and in the mountains part in Crimea on the mountains meadows (PL - polonina, Tatar language - yayla) - P. afra krymaea Sheljuzhko, 1929. Someone not accept this second taxon...
