Unfortunately, I have no experience in identifying flies on their "inner values" and for me the genitals of your fly look like those from "Blowflies" by Olga Sivell. Also, there are many images at:

I'm rather confident, that your fly is P. falcozi!

And: I've made a stupid mistake: I wrote av-bristle, but it should be the pv bristle!! Sorry for that!
1 pv: P. falcozi
2 pv: the other Protocalliphora
