Another Dytiscid - Berosus ordinatus
Elkland, Missouri, Dallas County, Missouri, USA
July 17, 2010
Size: 5.4 mm
Looking at the 1st abdominal segment - it looks divided. Must be another Dytiscidae, not Hydrophilidae. I apparantly have several species from my pond. Came to lights this summer.

Moved from ID Request.

Nice, sharp images made ID to the species level possible. Cannot quite confirm, as I cannot see the elytral apices direct, but what I can see, in combination with other features, are c/w this species.

Hydrophilidae
And I thought the 1st abdominal segment was divided . . .
Thanks!
I still have several Dytiscids vs Hydrophilids to sort out from this summer's lights.
