I found two of these on a sandy road. They seem to be the same as

Moved

Moved from Melanaethus.

I was wrong on this one. In doing some searching, I found that an old world species has become established in North America, Aethus nigritus. First confirmed image for the guide, though I suspect many are already posted and not recognized.

Moved

Moved from Cydninae. Examing the specimen you sent, it is clearly Melanaethus. Will take some time later tonight or tomorrow to determine species.

Not sure

Looking thru the described ranges of this subfamily in (1), the only species whose range would include Maine is Pangaeus bilineatus, but it certainly doesn't look like that species.

I suspect this is probably Melanaethus robustus, as I've seen a specimen that Tom Murray collected in MA. I'll check in Foerster's revision to see if that might help clear it up.

Edit: Apparent lack of any northeastern records in Froeschner's monograph. I do see that UoNH records online lists Microporus obliquus in NH. I would say the (at least) two options for your area are rather difficult to separate from photos. Seeing a specimen would clear up the identity.
