Today 29 Oct I found iin Soest (NL) a minute fly, which I think is Sciomyzid, possibly Pteromicra.

2 mm long
abdomen shining black, rest also black
2 facial setae
anal vein very short, almost absent

It doesn't really match any of the descriptions in the Dutch key of Revier & Van der Goot, however.
Who can help? Louis

No Louis, there is no costal break in Sciomyzidae.
I think it is Tony's department - Ephydridae.

Yes, it is an ephydrid - Limnellia quadrata. The wing pattern is characteristic, with a series of marks (the number varies) in the subcostal cell, and two darker spots attached to R4&5

Ah! Now I that took another look at it .. I see it does have that Ephydridae bristle on the antenna! Shock
Clearly a case of tunnel vision: the wing pattern seemed so sciomyzid to me !
Nikita and Tony: thanks!
