Dicaelus

is a safe and stronger placement for this beetle than subtribe Dicaelina. Image deserves further scrutiny but for this somewhat tricky one I'm not motivated without the specimen in hand.

Sent a query to Dr. Will Godwin

but haven't heard back yet...

not Dicaelus crenatus

in my opinion because elytra striae do not appear coarsely punctate as would be expected for that species. Is the image lying to me?

… Peter W. Messer, 26 March, 2015 - 7:06pm

elytral striae had me concerned as well...

there about 6 or so spmns in the UTIC...

See the holotype

here. Striae corasely punctate and intervals very convex to be sure. Maybe the other pinned specimens are misidentified?

… Peter W. Messer, 26 March, 2015 - 8:27pm

no spmns in the UTIC ID'ed to this sp...

I was just mentioning that there's a short series of spmns that appear to be this sp., what ever it is...

anonymous sourse suggested it mighe be D. ambiguus

which looks like a very good fit...

… Mike Quinn, 5 April, 2015 - 11:07pm

Relatively small body size better fits D. elongatus

(around 16 mm) whereas D. ambiguus starts no less than 19 mm. Lit: R mandible w lateral protuberance in ambiguus vs w/o protruberance in elongatus (as title image suggests). PWM: In comparing my reference specimens I note that elongatus has temple behind eye more abruptly curved and thus narrowed into a neck (as title image suggests) when compared to the long drawn out narrowing in ambiguus.
