Keroplatidae
Actually a keroplatid, a family once considered part of Mycetophilidae.

Thanks
for fixing this. Would you please look at the other image and see if it is correct? Also, can you explain how to tell the difference between the two?

Wing veins
Yes this looks like the same family but the wing veins near the base of the wing are hard too make out. In Keroplatidae the base of vein M is missing or weak. I know that this won't help you a lot. Without a detailed wing image it is hard to explain.

Spurs
On my previous image of a fungus gnat Eric R. Eaton remarked "Long spurs at tips of the tibial segments are diagnostic." I'm not sure if these spurs count as long.

Spurs
The spurs were the feature that made me think of the fungus gnats, and it matches the image in the 1st thumb pretty well.

Maybe
Thanks for the tip. I thought all fungus gnats had dark patches on the wings and didn't look there, but browsing the family now I see otherwise.
