D. oelandica fits better, but I wonder if it's big enough for oelandica (15-20 mm, the biggest of the Dioctria covered in my books of Netherlands, Belgium & Germany):
Wolff, Gebel, Geller-Grimm (2018): Die Raubfliegen Deutschlands
van den Broek, Schulten (2017):Fieldguide to the Robberflies of the Netherlands and Belgium
D. oelandica is a species of deciduous forests. Did you compare the female
D. cothurnata

Oh Yes!, D.cothurnata fits even better, plus it's apparently a wetland species, like the one in the photo. The problem is that both species have distributions restricted north of Pyrenees...

The proportions aren't right for D. oelandica. A D. cothurnata female is plausible, but it would be unusual to find that species in the center of Spain. So I suspect this is a related, Iberian species.

Thanks a lot Chris!
Then, the best option would be Dioctria spec.
