This genitalia was dissected from a
Pollenia collected specimen (Spain: Girona: 25.viii.2012) in a liquid trap and it was in bad condition.
It looked as
Pollenia angustigena (Rugnes 1991b ) spite hasn't an outer posthumeral setae. I looked the rudis species group keys (Rugnes 1987b ) and tried to match it with
P.luteovillosa, a similar species without outer ph.
I have no experience dissecting brachycera genitalia and
Pollenia species genitalia look very similar to me.

The third picture with the distiphallus in water. Nomenclature as in Rognes 1987b.

Hello Rafael, I've checked with Sivell, 2021, and Rognes, 1991: I think,
rudis species-group is correct and it's Rognes' type I =
angustigena or
rudis. The difference between both is the central sclerotisation in hypophallus which is usually broader than clear surface in distal part in
angustigena and narrower in
rudis. Your fly's one is the narrower =
rudis?
See the space between the arrows in the attached image.

Great! I didn't know that difference in the width of the central sclerotisation on hypophallus, perhaps is in Sivell 2021. Thanks!
