This fly joined me to share a drink. Literally, it landed on the lid of my bottle of Gatorade. Here it is drinking my sweat.

New Hampshire, USA, near tree line in the White Mountains, July 3 2010.

Size 7 mm. Looks like Rhamphomyia. Is a more specific ID possible?

Proboscis is about half body length.

Sorry, it is Rhamphomyia but proper literature for most Nearctic Rhamphomyia is wanting.

Is there a more modern guide to American subgenera than Melander 1928 (Genera Insectorum 185)?

I read that the loss of separate R4 has occurred several times in Empidini, so I assume that the genus Rhamphomyia will sooner or later be restricted to a much smaller group and most other subgenera promoted to genus.

That is correct and as far as I am aware there is little more inclusive on the subgenera subject in the Nearctic than Melander's work. I can do some further checking, though.
