Hi, I had to opportunity to take pictures at different angles from this fly, so many characters are visible (Spain: Tarragona province, 17.v.2025). Could it be Cylindromyia pusilla (female)?
Hind tibia with 1 - 2 pv-bristles
Apical scutellar bristles [EDIT] present.
Abdomen without discal bristles

First of all, it is a male, check the elongated pulvilli !

Secondly, there are basal scutellar bristles, so it is in the brassicaria group.
The other features you mentio are often difficult to assess from pics ... ther definitely should be apical scutellars !

Thanks Theo for the correction about sex.
But if Hind tibia with 1 - 2 pv-bristles it should not be brassicaria (using Cerretti 2010a), but interrupta, intermedia, auriceps or scapularis.
I have seen the apical scutellar bristles.
So it could be intermedia, auriceps or scapularis.
If Abdomen without discal bristles is less likely auriceps (=abdomen usually with discal bristles).
