I am not 100% sure, but it seems to be an Heterostylodes sp. (Anthomyiidae)

The shape of the ovipositior in the second image suggests
Phorbia, but I realise the pv apical seta on the hind tibia is not visible in these images.

I've never seen Heteostylodes, but the key says it should have the mouth edge protruding beyond the parafrontal angle (rather like Egle). Phorbia seems a better fit here on that count too.

And if it is Phorbia, from the features I can see (crossed interfrontals, orbital and frontal bristles not in a straight line, t2 with 1av+1ad+2pd, dorsal margin of cerci not straight in distal half, genal setae not uniserial),
Ph. fumigata would seem to fit best.

Assuming there are no similar species in Italy that lack from your key. :P

Thanks a lot for your attention, here the list from the Italian fauna about Phorbia genus:
Phorbia Robineau-Desvoidy, 1830
Phorbia curvicauda (Zetterstedt, 1845) (N) (*)
Phorbia fumigata (Meigen, 1826) (S)
Phorbia italica Ackland & Michelsen, 1987 (N)
Phorbia juncorum Ringdahl, 1959 (N)
I add another image, with the Phorbia upside-down:D, I hope it can help in some way.
Best regards
Claudio

Good point :D Of the four Italian species listed, only fumigata and juncorum are covered in the British key. We will have to wait for an expert to see if this one is identifiable.
