Lovely!

Hesperiidae, Pyrginae. "Tough" one. Immediately clear it must be a Quadrus sp. (looking at the "c" on the forewing), and it is either Quadrus cerialis or Quadrus lugubris. Comparing the 2 it is none of them. Look like a mixture of the two. However, looking even more carefully it is clear that it only can be Quadrus lugubris. My arguments: The markings in yours are not so strong than in usually seen Lugubris. The main criteria are the 2 little spots at the apex of the forewing, mostly the "shape" or direction. Looking at the left forewing: In Cerialis it is a clear ">" shaped order, whereas in Lugubris it is the other way round, so "<" shaped, like in yours.
Here are some more pictures to compare (as usual ;-)...):

Note the ">" shaped order of the 3 tiny spots.
