The only Hemipenthes that look similar to H. maura are H. villeneuvi (Pyrenees and Alps) y H. vockerothi (Spanish endemism). Those two are told apart from maura due to the absence of fenestrae in the dark areas of the wings. So it cannot be any of those. There is a species from southern Russia that I don't know anything about: H. eversmanni. Unless it is that one, no other chance than maura. Because one thing is certain: those two specimens are Hemipenthes ;)
