Size: ~5mm
Floating in a puddle (dead) near Soda Dam.

Moved tentatively; that's what i thought -- thanks much, Rick
who might know for sure? Stewart Peck? [he's traveling, tho]

Moved from Beetles.

very cool! looks like an agyrtid but i'm not sure yet
make sure not to post images to guide pages beyond the ID level you are fully comfortable with; whenever in doubt, place at order page.
there is no mechanism to weed out ID errors, and those tend to be perpetuated; we have enough misID'd pics as is...

Moved from Water Penny Beetles.

I did not expect that ID, I was way off! I'll try not post beyond what I think is correct again however, based on what I have read I may have done that already.

not sure but
This looks a lot like one I found in the Sandia Mountains, NM, which I have labeled as Agyrtidae: Apteroloma arizonicum. But I am pretty weak on this family and would want that checked.

pls take a look at...

I think this beetle's hind tarsi are countable as 5 in the picture, so I reject Myceto...

hmm... hind tarsi not visible there, except for the apices

By "this beetle" I mean Mark's beetle from the Jemez! It is not Myceto because it has 5 hind tarsi! Or maybe I misunderstood. Are you just asking me to think about that Mycetophagus specimen? In which case this is a strange place to put it.

oh... a misunderstanding, sorry
i was asking you to comment the Mycetophagus, and you answered that request, so i assumed 'this' to refer to the one on the thumbnail.
that request of mine was unrelated to the agyrtid

On the thumbnail Mycetophagus, I can't help. I have not found anything like that one here in NM. If it is distinctus, then it is quite a bit outside normal range but I've found a few PNW things in our mountains. pluripunctatus is quite variable but I doubt it would look like this. Sorry. I would need the antenna much clearer.

yes some PNW clickers pop up in the NM (and AZ) mountains; whether those are disjunct populations or they occur throughout the Rockies I am not yet sure.

Thanks Rick for your input
There was another slightly smaller one with it but, I lost it in the debris otherwise, UNM would have had one also. I'll keep my eyes open for one this summer/fall.
