So, wait, I'm a bit lost in the taxonomy. Is the bottom line that
Ascoliocereus sanborni
=
Hypolithus barbatus
=
Cryptohypnus sanborni
(Horn)?

Hypolithus barbatus

This is the taxonomy reflected in both American Beetles and Stibick's 1976 revision of the tribe.

Old genus guide page says
"A single species in our area", so would this other image move here and the genus go away?

that may not be Hypolithus...
working on the problem now. The literature is muddy and the MCZ is out-of-date, many of those species now in Negastriinae.

Hypolithus barbatus
looks likely.

thanks, Don...
but the type of its allegedly synonymous
Cryptohypnus sanborni
Horn, 1871
looks nothing like our guy :-/
Hypothesis no. 3:
Margaiostus
cf.
grandicollis
(LeConte, 1863)

C'est la guerre.
1) the MCZ type looks pretty messed up/gummed up.
2) Our good series of identified specimens from the White Mountains and far northern New Hampshire look like Tom's photo, which is based on a specimen from Dixville (far north),
3) our specimens were identified by Dietrich, who did the Elateridae of New York.
One very clear thing in Tom's photo are the very prominent postero-lateral tubercles of the pronotum, which are shared with the type of C. sanborni, but not with M. grandicollis.
As a non-clicker specialist, this is as far as I go.

thanks a lot for a detailed argument
i surrender and will settle for
Hypnoidus rivularis
(Gyllenhal, 1827), of course: ref. collection shall prevail. Sorry I took so much of your time, Don :-/

I'm uncertain
if this is going to be called Hypnoidus rivularis, or Hypolithus barbatus.

i've completely lost my mind...
sorry, folks -- i meant, of course, the sp. suggested by Don ('barbatus'), which the
Checklist of the Beetles of Canada and Alaska
cites as
Ascoliocerus sanborni
(Horn) =
barbatus
(J.R.Sahlberg)
do whatever you want with all this taxonomy, i have no idea which system is being followed in the guide
…

I'll keep it simple
and go with Hypolithus barbatus, since that's in Neartica.com. If anyone else has a different opinion, and wants to do something different with the taxonomy, I'll leave that to them.

nah,
that was a crappy call of mine. it's embarrassing i can't delete it... i'm all over the place; now i suspect something like
Hypnoidus
rather and pray for someone with a ref. collection to take a look at it
