I have a North Carolina specimen (no photo available, sorry) that keys out to a female C. fimbriolatus with the exception that there is no yellow margin anywhere. Comments or suggestions gratefully accepted.

Sometimes the yellow is more or less prominent (more like a thin brown line than yellow) although I personally haven't seen one completely lacking in some form of contrast between the margin and dorsal sides of the elytra. I'm not particularly aware of these other than as pests though, it's always possible that I have overlooked a particular morph. It is the only species in that genus in our area I believe, you're sure it's not Dytiscus? Very similar, don't know if there is a completely dark species in the SE US or not. Nasty little buggers, always on the look out when I'm working in my ponds.
