Prioninae? - Archodontes melanopus Prioninae? - Archodontes melanopus

Moved from Macrotomini.

Moved from Longhorned Beetles to Macrotomini, the common denominator for the two IDs Ted proposed below. Let me know if this would be better placed at subfamily level, or somewhere else...

After looking at it again...
...I can't see how it could be anything other than Archodontes melanopus serrulatus. It's holding the mandibles more horizontally than I would expect for this species but otherwise has the general appearance of that species, with the pronotal shape matching subspecies serrulatus (known from the southern U.S. west of the Mississippi River west to Arizona). The short 3rd antennomere excludes Strongylaspis (which is restricted in the U.S. to southern Florida), and the lack of carinae on top of the mandibles and obtuse antennal tubercles exclude the widespread Mallodon dasystomus, Nothopleurus (west Texas to Arizona and southern California), Neomallodon (Arizona), and Stenodontes (southern Florida). Utah is an interesting distributional record - to my knowledge none of the Macrotomini have been recorded from the state. I don't suppose you have the specimen?

Thanks for the ID & explanation--
I didn't see your comments till now. If you edit a preexisting comment, it doesn't trigger an email notification. I assume that's what happened here. Or else I just missed the email somehow.

Afraid I don't have the specimen. I don't generally collect insects unless I have a specific purpose.

Too bad...
...In this case, the specific purpose would have been a new state record :)

Oh well, now we know it's there - hopefully someone will run into it again.

I didn't edit anything.

My beetle I found recently th
My beetle I found recently that is identical to that one is 5.3cm in length. I was just researching this beetle I found in my tree bark and well this one matches it perfectly.

In the photo you added, the mandibles don't look nearly so carinate on top as in this photo, and the antennal tubercles don't look so acute. That would suggest Archodontes melanopus, although that species usually holds its mandibles more vertically.

I suggest leaving it here for a bit and see if anyone else chimes in.

Looks like...
...Mallodon dasystomus (horizontal mandibles, not retracted basally), but Utah seems an odd distributional record.

I've added
a detail from the only other shot I have of this individual, although I don't imagine it gives you any new information.

Would these images best be placed at species, genus, or subfamily level?

Moved from Beetles.
