Hi, I think this is Asteiidae. I made some interesting videos of it, I'll show them (how to put a viewable Youtube link here?). They were on dead wood (freshly cut). Some 2 mms.

Could this one be Paranthomyza nitida (male)?

I think Asteiidae was correct, Leiomyza sp.

for example -- for the link http://www.youtube.com/watch?v=NieRx4HPLTs
you should take the last part NieRx4HPLTs , after you must select this code and click in the youtube button.
Yes, asteiid, no doubts. I agree with Stéphane.

These rows of veryvery short hairs are characteristic to this family, aren't they?

look at the wing venation. There are no transversal veins conspicuous (there are 2 very near/near the base of the wing - not visible in your photos). I only know this family to have this feature.
In your photos is not visible but the arista is peculiar -- it has an alternate pair of hairs along the arista.

Oh, I see now:|. When I saw the females of Paranthomyza nitida, I also photopraphed what I thought was a male of this anthomyzid species. Maybe it was Leiomyza sp. as well.

Here's the YouTube Video
It is in bigger resolution when you watch it on Youtube webpage (pls search for Leiomyza).

It looks as if it is difficult even for them to tell males and females apart...
I need to make a last confirmation but it looks like Leiomyza scathophagina with the yellow knobs on the halteres.

Hmm, dark knobs of the halteres after all: Leiomyza dudai Sabrosky, 1956 (dorsocentral setae about their length removed from the anterior margin of the scutellum).
