Paul,
a small, about 3mm black empis males. Hairs on abdomen black, halteres black , two bristles on scutellum. The penis is pretty typical, I think. Using Chvala I come to E. praevia, but the penis looks not the same! Yet looking in Collin's work it comes a quite a bit closer.
What is your opinion? Sorry for the just terrible photo.If it is praevia, it is at least not often recorded from the Netherlands, right?

Well, I see that the photo is indeed that miserable, that even the real specialists can't make anything out of it? ;-)

Indeed when comparing the drawings of Chvala and Collin it's hard to believe they are talking about the same species.

I think the drawing in Chvála's book is missing the apical, translucent part (also visible in the above picture) perhaps because it is rather variable in shape. In the picture above it is larger than in Collin's illustration; in the sketch I drew in Chvála's book (to remind me that it's aedeagus looked differently from Chvála's picture), it is yet smaller.
