none of the others..
no! Acrocerids are ENDOPARASITOIDS of spiders. (usually they parasite Lycosidae spiders). It is unique feature among Diptera.
Maybe an Acrocera' I cannot see wing venation so it turns out more hard.

I think I have a 99% trust in this ID :d
Acrocera sanguinea (before it was known as A. trigramma:), according Seguy if fits very well. ;)
The species is known for Spain. ;)

I agree with Jorge.
It is clearly Acrocera or Paracrocera, and given the colouration,
A. sanguinea is the first thing that comes in mind.

this species was confirmed by my friend Evert Schlinger today. :) It is A. sanguinea (for final confirmation, it would be wise to examine the genitalia)

Thanks Theo for confirmation too. ;)
