One thing you can be 100% sure of is that that is not
malvae! Identifying
Pyrgus from the upperside alone is often possible but there are several species you really need an underside of too. In my opinion this is most likely a very weakly marked large grizzled skipper,
alveus. The only other serious contenders are carline skipper,
carlinae, which usually has a much better defined 'c' on the forewings and olive skipper,
serratulae, which is instantly identifiable from the underside but extremely variable on the upperside. A real outsider would be Warren's skipper,
warrenensis, which flies in principle at high altitudes in that general region but is much more local and scarce than the other species I mentioned. I think it is over earlier too and only mention it for completeness. It looks like a very small, weakly marked
alveus.
Here are some pictures of the species I mentioned:

alveus)

(weakly marked female

warrenensis)
I go for
alveus!
