Moved to genus page
Keyed down to genus Tropisternus using the key from "Nevada Hydrophilidae (Coleoptera)" [American Midland Naturalist, Vol. 52 No. 1 (Jul., 1954), pp. 164-174]
The journal doesn't cover most eastern species, so genus is as far as I'll get until I get my hands on a key for eastern/NA species.

Tropisternus?
Reminds me most of the genus Tropisternus, but moving to family page for now.

Yes, Tropisternus is possible...
though I'm still somewhat unsure. Of all the beetles that I found in that small puddle by the gorge, this individual was the only Hydrophilid that I found.
