Could you post some of my midge photos and notes on your mystery midge
page?

My best guess for the first 3 photos is Paraphaenocladius, though it's
hard to be certain as the drawings in Wiederholm don't capture all the
details of the actual specimens:

"paraphaenocladius?1_whole.jpg":

"paraphaenocladius?2_whole.jpg":

"paraphaenocladius?3_ment.jpg":

I have 2 specimen types that I've lumped under
'limnophyes/paralimnophyes', though they seem to be consistently
distinguishable and I'm guessing that I might have both limnophyes and
paralimnophyes though I'm not too certain about which is which:

"limnophyes?1_whole.jpg":

"paralimnophyes?3_whole.jpg":

"paralimnophyes?4_whole.jpg":

And the final pair - are these pseudosmittia?

"pseudosmittia_VP.jpg"

A couple more midge photos.

Looks Diamesinae-like, but not quite like other Diamesa that I've seen.
The median tooth (teeth?) looks pretty distinctive as seen in the photo, 8
pairs of laterals, and a bit of a ventromental plate bulge showing. I have
a handful of these in a long core.

"diamesinae_vp.jpg":

Any corrections, confirmations would be appreciated.
