A nice day,
perhaps someone is able to determine beyond genus.
Today in mixed wood on light, Lower Austria at round 550m.
Many thanks in advance and best regards
Johann

It might be
Diamesa (long r-m crossvein, swollen fourth tarsomeres, found in the cool season).
Some other Diamesinae and a very few Orthocladiinae have similarly shaped fourth tarsomeres.
