On the Italian Entomologist Forum (FEI) recently Matteo Magnani posted the following photos.
Could this be a
Trixa?

Yes, looks like
Trixa conspersa but all of the species keying features are slightly obscured or out of focus ;)

Trixa caerulescens var. alpina
the status of this taxon is unclear.

Thanks a lot Chris and Theo for your answers. Yes, I agree about the the poor visibility of the keying features, but this happens almost always in photos of living insects.
T. coerulescens was my guess too; in my opinion legs are much darker in
T. conspersa, but maybe this is not a diagnostic character.
Matteo's guess was
T. alpina, but I read on Cerretti's thesis about the uncertain status of
alpina, Theo's statement seems the perfect balance.
