Tanytarsini from Massachusetts, USA, May 2009. Is genus ID possible?
Additional views:
Thorax,
Head,
Wing,
Genitalia 1,
Genitalia 2
I darkened this picture to make the midge more visible. It looked nearly transparent.
Wing length 1.6mm.

I think, its may be Stempelinella, have you some of them in you region?

There are several species of
Stempellinella in northeast North America. Note the long R4+5 here. I thought that ruled out
Stempellinella.

It is at most very small. I don't know the difference between small and absent.

So it isnt Stempellni sub-tribe, i cant see appendeges of genitalia, and pectens of t3 and t2, thats why a cant say anithing about genus/// And i dont know nothing about north americn fauna. Maybe you tried on listserver of Chirobomidae homepage http://insects.ummz.lsa.umich.edu/~ethanbr/chiro/internet_res.html
