This rather large (about 5mm) Cecidomyiidae with white tarsomere was laying eggs on a dead trunc. There were several of them including a male. We've collected a male and a female.
Does someone know the species or literature to key the species?

I think this is probably
Winnertzia, based on the venation. I understand the larvae feed on fungi.

Bases on wing venation and short first tarsomere plus biology it should be a Winnertziinae. From what I can find on the internet Winnertzia's are rather small. Maybe another genus from this subfamily?

The best starting point is
