Hello,
I compared this fly with Nikita's pictures
( http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=1670 ) and mine doesn't seem to have this dark parts on the femora (Nikita's nailed fly has neither).
Is that of any importance or could it be the same species ?
I saw the animal a week ago, near Heerlen.

Another
Clusiodes. I will get on to it tonight or tomorrow morning.

I cannot get further than subgenus
Clusiaria with any certainty. Possibly
C. (Clusiaria) apicalis or
C. (Clusiaria) geomyzina (of which only the first was recorded from the Netherlands) but a dorsal view is necessary (for example for the amount of clouding on the wing) but I cannot even rule out
C. (Clusiaria) ruficollis, as the thorax is not as deep black as in the specimens depicted
HERE.

Hi Ben and Paul,
It looks like the dorsal suface of the thorax is partly "rusty brown". This would indicate that we are not dealing with
apicalis/
geomyzina, but with
ruficollis, which both should have the thorax black (appart from white stripe in front of the wing base). I have to admit though that in comparison with the specimens of
ruficollis that I have seen, it is extremely dark.
I suppose you didn't collect the specimen, Ben?

Hello Jan Willem and Paul,
I didn't collect the fly but I can offer a more or less dorsal view that shows the, according to you both, for Clusiodes ruficollis typical brown coloured thorax.
I saw the 3 mm-fly on a dead tree trunk near a little stream (Eyserbeek).
Many thanks to you both,
Ben

That settles it:
C. ruficollis.
