Thanks for taking a look at these. If you look up top at the placement, I think you'll find that it currently is placed in Noteridae vs. Dytiscid. The title under photo which states "Dytiscid" is from my original posting. I typically never update these titles (feels like erasing the evidence of my past mistakes), but I'll do so for this one to prevent further confusion. And I'll move it back to the genus level. Again, thanks for your time and expertise on these.

to update the titles to reflect corrections in ID, and to do this for all images of a specimen (which hasn't yet been done in this case). This will avoid confusion and/or unnecessary "corrections" by other people in the future.

To avoid "erasing the evidence of past mistakes" you could add a note to the body of the message saying something like "originally IDed as such-and-such" which would also benefit anyone who might have made the same mistake. It would also be helpful to add this kind of info to the appropriate Guide page(s) for future reference.

On a different topic, what does "Midlantic" mean on this page?

hopefully no one is confused anymore.

"Midlantic" is an unofficial fast-type of "Mid-Atlantic", one of the nine or so geographic regions of the US. I've updated that one also.
