Moved
Even without confirmation of seeing the hypomeron, I am pretty sure this is what it is....

Moved from Danosoma.

 
Are there any western records?
I recently collected two 17 mm specimens with this same blotchy pattern off a cottonwood along the Jordan River in Salt Lake. The hypomeron has distinct tarsal grooves so they aren't Danosoma.

There are a few other Lacon not on the guide which I am not acquainted with.

If I upload photographs, they would show the dorsal surface between two sepperate photos.

 
Hi Jonathan
If you post the images on BG, please do nice, straight on dorsal and ventral shots. You are correct; if there are grooves on the hypomeron, it is not Danosoma. I would have to check the old Arnett review to see if there is anything missing. They could just be denuded specimens of something normally more scaly.

I live in Salt Lake City and as soon as my monograph on the Elateridae of the southeast gets published, I will be working on the clickers of AZ, UT, NM, and CO.

Please feel free to email me (email on my profile) if you want to chat more. When I start my work, I will want to examine your specimens for the data points!

 
I have lots on unsorted click
I have lots on unsorted clickers from Utah and se Arizona, not as many from Colorado or New Mexico. You are welcome to look through them when you need.

I'll see if I can take any photographs worth posting.

Can we see a shot of the underside...
I cannot confidently rule-out Lacon marmoratus from this pic.

 
No underside
I regretfully didn't take a look at the underside. Too bad...I'm seeing now how similar these two genuses are!
