per H.R. Burke: probably Pseudanthonomus tomentosulus Dietz
...definitely not Anthonomnus rileyi Clark & Burke. As best I can tell from the photo it has a 6-segmented funicle as opposed to the 7-segemnted one of A. rileyi. Furthermore, the body form is different, for example, it has the sides of the prothorax fairly strongly rounded while those of A. rileyi are less so. These are the only characters that I can see from the dorsal view that definitely separate them. It is probably Pseudanthonomus tomentosulus Dietz but to be sure I would have to have a specimen in hand. P. tomentosulus is known to occur in the Chiricahuas as well as elsewhere in Arizona. The male median lobe of P. tomentosulus is distinctive, very different from any other in the genus (see Clark 1987. Coleopterists Bulletin 41(3):263-285). This is the best I can do without specimens. Cheers. Horace

was this spmn collected?
Graham, yours in a match for what I ID'ed as A. rileyi:

which shouldn't occur in AZ as evidence suggests it's host specific on Juniperus ashei which barely occurs w. of the Pecos...

No specimen, Mike!
I'll be on the lookout for it next time I'm in the area though. Cool weevil.
