I found this strange fly on a young Citrus tree. Looks like Drosophilidae with very dark wing venation.

Ephydridae I think [maybe-ish] |t and if so possibly a
Philygria sp. as a guess [as usual]

Your guess is my certainty. :)
My first photos of a specimen belonging to this family. |t
Thanks, once again,
Roger!!!

I agree with Roger's guess - but I don't recognise the species.

Perfect, Tony! I can remove this 'possible'.
There are 8 species in Spain:
Philygria femorata
Philygria flavipes
Philygria interrupta
Philygria interstincta
Philygria obtecta
Philygria posticata
Philygria stictica
Philygria vittipennis
Thanks! |t

Could be
Philygria stictica, but the small appendix on vein M is unusual in my experience.

Thanks
Tony. Yes , this appendix is strange.
Are there more species with this appendix or could it be some genetic error?

In
Philygria punctatonervosa there are many short appendices on the veins, and "mistakes" can occur in other species. In
Parydra, quite a long appendix occurs on R2+3 in a wide range of species, though it can be absent in some individuals.

So theses appendices are of low value for their identification. |t
Thanks for the explanation!
