Moved
Moved from Dytiscus hybridus.

Very unlikely hybridus; coloration is more indicative of harrisii but not definitive

D. hybridus
Based on coloration of the legs and pronotum.

Thanks
Thanks for that! Convinced it's Dytiscus marginicollis now. Found more info at http://www.entomology.ualberta.ca/searching_species_print.php?b=Coleoptera&c=7&s=4253&sn=#

marginicollis very unlikely
8 Dytiscus spp. listed for your state, but D. marginicollis is not among them(1)

Yup
Oops, yeah, seems to be a lot of Dytiscinae that look similar. Could be hybridus or harrisii... good lesson for me to take a ventral photo next time.
