This one i am not sure about, I feel like I can't properly key it to family even.. I also have tried it in Calliphoridae, Rhinophoridae, Sarcophagidae, Tachinidae and Muscidae, without finding a match.. I think most likely Sarcophagidae tho.

The short-petiolate cell r5 and rounded bend in vein M point to Tachinidae.

---

Thank you, it does not have a very obvious postscutellum. I also forgot to mention the size which is about 4mm.

---

The calypters look too large for Rhinophoridae.

To my knowledge Sarcophagidae always have a sharper bend in vein M, and your fly's arista is bare.

Calliphoridae normally have a plumose arista. There are exceptions in subfamily Melanomyinae, which may also have a gentle bend in vein M. To my knowledge, no Melanomyinae have petiolate cell r5.

Muscidae never have petiolate cell r5.

To run through the Central European key you need the arrangement of the postsutural intra-alars.

Thank you! So I actually have two males from the same locality at the same day, and the one in the original post have mostly broken bristles. So I checked the other specimen as well. To me it looks like there is only one postsutural ia

---

it is not a Sarc and my gut feeling is Rhinophoridae.
Can you check the lappets of posterior spiracle ?

Theo

---

Thank you, its difficult to get a proper picture of the posterior spiracle, but it looks like the lappets stand straight out

---

Here is a picture showing the postscutellum.

---

Yeap, I’d say that is a Rhinophoidae, thanks.

my guess is one of those rare Phyto ‘s ?

can you tell whether the first supra-alar bristle is strong or small .
what about sternites, visible or covered by tergites ?


Theo

---

Thank you! 1st supra-alar is slightly weaker than the notopleurals.

---

Sternits are visible

---

I am starting to think Loewia (Tachinidae ) ?


Theo

---

Thank you! I think you are right with Tachinidae, I believe after going trough the key several times it should be Microsoma exiguum

---

The wing venation is indeed very similar. Nine out if ten, I see females, males are (apparently) not present in my active memory :)


Theo

Yeah, I have only seen females before too.
