Hello,
This one was found a few days ago in an urban flat (on a window), near Paris. Length about 2,1 - 2,3 mm.
I suppose it is Cecidomyiidae, and using the key given in the
Manual of Nearctic Diptera (Tome I, pp. 261 and following) I get Lestremiini.
Do you agree with my ID ?
Is it possible to go further ? (I found one which seems very similar to mine on
this page and they call it
Lestremia, but I don't know if this can be trusted.)
The specimen died shortly after being captured for the soohting, and I still have it (dry). So if any one wants it, feel free to ask...

Based mostly on the same source, I also say Lestremiini cf.
Lestremia.
Allarete has pale forks of M, as your midge has. I think the antenna closeup rules out that genus.
I think my gallery shot is also
Lestremia:

Jaschhof's revisions have made Lestremiini and Lestremiinae synonymous. Other tribes have been moved to new subfamilies.

Thank you for your answer.
Trying to go further with the key (an comparing with your midge), I realise mine should be a female. Is it correct ?
If so, then following the key, the choice should be between
Anaretella,
Conarete and
Lestremia. The flagelomere's shape (figs 49 & 50, p 265) seems to fit better with
Lestremia than with
Anaretella (I saw noting for
Conarete female among the flagelomere's shemas). In counterpart we have shemas of
Conarete's fore tarsus (fig 65, p. 268) and they seem more robust than my specimen's tarsus. Moreover, the nine flagelomere's criteria is in favor of
Lestremia.
I don't know if this is enough to conclude it is
Lestremia ?
