Tachinid/Sarcophagid (?) specimen in search of id

Hello,

Recently, I collected this dead specimen of Muscoid fly from my garden and I am trying to properly identify it. I think that it may be something in Anthomyiidae rather than Muscidae, but I am not sure. Any help with the identification (at family, genus or even species level) is welcome!

The specimen was found and collected in my urban garden in Western Athens, Attica, Greece in 24/5/21. I still have it in the freezer, so if more photos of specific external characters are needed for proper identification, just tell me!

Unfortunately, the photos were too large for uploading in the thread, so you can find them here:https://www.inatu...s/80639012

Thanks!

Might be Tachinidae
(or maybe Sarcophagidae).

Change the title to attract the attention of Theo Zeegers

the lower calypter seems small, it might be Mimidexia (Rhinophoridae ) ?

*. heck postscutellum
* check posterior spiracle

Both virtually impossible to photograph Sad

Thanks for the possible id! Grin In that case, I will also check ''The world woodlouse flies (Diptera, Rhinophoridae) by Cerretti et al. 2020 (https://zookeys.pensoft.net/article/37775/) to see if the characters given for Tromodesia (synonymous with Mimodexia in the paper) match my specimen and also ''The Rhinophoridae (Diptera) of Israel'' by Kugler 1978, to see if the description of Tromodesia angustifrons (the only species known from Greece) matches.

On top of that, I will try to take photos of the postscutellum with my stereoscope, but isn't the posterior spiracle only visible in larvae and pupae?

Thanks!

Posterior spiracle = posterior breathing opening under wing base.
We need to see the lappets closing this opening “ operculum”

I managed to take photos of the postscutellum and the spircle (the latter isn't too good, but may be helpful?). I added them on the above-given link and below:

Excellent, great work. Definitely a Rhinophoridae, I’d say.
So I stick to Tromodesia / Mimodexia
