Found on steep, caliche slope. This beetle was very spastic; tumbling around at the slightest disturbance while being photographed.

Moved from Pubescent Pachys.


suspect P. haematodes Suffrian

let's keep it, in the hopes you'll find another one...
...and replace this series with sharper pics; might well be a nice one

Moved from ID Request.

Cryptocephalus sp.

looks more like a rather nice Pachybrachis to me
not much to work with here, alas

Ideally, what would you like to see?
Hey, maybe there will be a reshoot! First priority is a sharp dorsal shot, i.e. from above. What next, =v=? Antenna? Feet? End of abdomen?

just a sharper, higher-res habitus photo showing the head
head tends to look muffintoppy in Pachy~ vs fully retractable (flush) in Cryptocephalus (thence the name)

the dull appearance here speaks strongly towards Pachy~, too.
pls note though that this is an enormous genus with scores of undescribed spp. in the southwest --and Ron is of course right about dissection: more often than not, there's no way around (a few may be recognizable, but whatever the case, only an expert could narrow it downd past genus --and i'm afraid E.G. Riley is the only one who could help)
bottom line: collect, collect, collect.

Perfect! Thanks =v=

Wasn't the best
but I thought I'd take a shot getting some advice on where to start on ID. In the future I will likely just collect specimens as small as this to ID myself.

Anthony, feel free to submit anything, any time.
I wasn't commenting adversely on your images; I was trying to draw out more guidelines for you and me both. There have been times with beetles when feet were important, and that blew me away when I found out.

There is an article in Forums that gets into some of this. A link:

I was just getting at the fac
I was just getting at the fact that characters on tiny specimens are probably best viewed in hand, thanks for the link!

My pleasure, Anthony.
Some specimens have to be dissected and go under the microscope to be IDed. However, more and more insects that once "couldn't" be IDed from photos are now being identified.
