Hello all,
I could not identify this individual of Nematocera. It was caught in an emergence trap in moist Typha vegetation in The Netherlands.
Does anybody know what I'm looking at?
Thanks, Jan Kuper

What's the length? Is it possible to make venation visible?

Scatopsidae

Isn't the costa too long for Scatopsidae? I have no better suggestion by the way.

Cecidomyiidae, Lestremiinae?

Yes, taking another look at the wing veins it could be somewhere close to
Lestremia.

Thanks for your replies! I must ask my colleague to provide a better picture for the venation. That will be later. In the mean time I can tell that the venation does not look at all of what I've seen from Cecidomyiidae, there's no gap in the costa at the top of the wing, it has five tarsal segments (of which the first is not very small). Following the table of Oosterbroek, Scatopsidae would indeed be my best guess, but it doesn't look like one (?)

Subfamily Lestremiinae has five tarsomeres, first longer than second.
