Cybister fimbriolatus (or not?) - Cybister explanatus

Fish Springs National Wildlife Refuge, Juab County, Utah, USA
July 18, 2016
Just a day earlier, I had been talking to one of the speakers from the Dragonfly Society of the Americas annual meeting, speculating on why insects with aquatic adults were so much less colorful than their terrestrial or aerial counterparts. Then, while on a stakeout for Giant Darner (Anax walsinghami), I saw what looked like a huge green seed or nut in the water. Turned out to be this dead diving beetle. My best guess is that it's an unusually bright Cybister fimbriolatus, but I'm open to alternative ideas....

Very cool! The key character is the acuminate point on the apicoventral margin on the metafemur. I've never caught this species so count me green with envy. Also, this may be an interesting range extension. I don't think the species has been taken in Utah before.

Woohoo!
First state record, awesome! Fish Springs seems like a likely place for aquatic invert range extensions, and first state records, it's by far the largest wetland complex in a landscape that's otherwise mostly dry for many miles around, and pretty close to the state line. And a new species for the Guide, too! Thanks for IDing it!

("green with envy", heh heh heh....)
