I wouldn't like to say which
Tachina spp. it is - the base colour is either very dark or the photo has too much contrast perhaps?

No, is the colour of the fly.

Anybody knows the difference between these species?

In simple terms the 2 species are split using the colour of the fore tarsus and the frons/eye ratio. The problem is that these are very hard to tell from the photo but the fore tarsus does look very dark, which *might* suggest
magnicornis. BUT (and this is a big but!) you are assuming this is either
fera or
magnicornis, but I think in southern Europe there are other species.

Oh, sorry. I supposed that there are only these two species with these coloration, but clearly can be any other species. I'm completely new in Dipterans, excuse my big error!

No problem :) The Central European key (Tschorsnig & Herting, 1994) is a good starting point with tachinids but it is only accurate in north/central Europe. In Spain you might have to consult local literature and perhaps discuss this with Spanish dipterists to get a more complete picture :)
