Difficult. There seem to be only 2 post IA on thorax, that should be a big clue (favouring Acemyiini, I guess).
Any chance of a pic showing lateral view, o matter how bad ?

No, sorry :-( the camera could'nt get into the wall, to take a shot more ventrally.
There are clearly 2 post sutural intra-alar setae. If I add two postsutural intra-alar setae separated by a distance equal at most to distance between the first seta and the suture, then it is also left Acemya
I add another dorsolateral view.

The first flagellomere of Acemya
is pointed at the upper tip, not rounded as usual in Tachinidae.

Thanks, John, then it's not Acemyia

Even if the view of the flagellomere is not good, Acemyia
looks quite different.

Well, it could be a female Stomina, but I am not totally sure.
