Interestingly, the reference that Mandy mentions, in SONA, indicates that there should be 4 North American species. I had to do some digging to find the fourth species: H. semiflavus, which you can apparently find in the Yukon.

The frontal view of the head (males only?) seems somewhat exaggerated, but I suppose one has to view the specimen directly from in front and close-up (under the microscope).

Yes, Hypselistes seems like a good possibility, and the image of a male specimen that I have from the Biodiversity Institute of Ontario (Hypselistes florens), strongly resembles your male, Charley, including cephalic lobes.

I agree that this one matches all the Hypselistes currently in the guide. SONA says that this genus is supposed to have an hourglass shaped cephalic lobe, though. Maybe it's just so slight that it's not visible in yours or the other photos? Not sure. If you have a copy of SONA, check out pg. 141, top of the page. Based on that diagram, it seems like we should be able to see more of that hourglass shape in all the photos, but I'm just speculating. We should see what the others say. ([edit] Oops, nevermind! It's only the males that have the hourglass-shaped cephalic lobe.)
