"Adaleres humeralis Casey The locality fits too." [Dr. O'Brien]

Dr. O'Brien identified this weevil as Adaleres humeralis Casey.

This is a new species for BugGuide.
Could a new page be created for it ?

i've been wrong before, but am pretty sure it's in this tribe...

...that has any number of genera in California...
will ask Dr O'Brien

You have been right before many times, =V= !!

Thanks for your expert feedback & placement, and thanks for asking Dr. O'Brien !!
I look forward to solving this urban mystery.

I did some digging in the mean time and found 42 species in 9 genera in California.
The largest (# spp.) genus being Dyslobus, which doesn't seem to match.
A couple of genera have only one CA species and are in BugGuide, and ... don't match.
This leaves:
* Adaleres, which seems to resemble somewhat, has 3 CA spp., of which 2 in BG (that don't match).
* Crocidema californica
* Dirotognathus sordidus
* Miloderes, with 3 CA spp.
* Panscopus, with 9 CA spp., of which 2 in BG (that don't match).
* Paracimbocera, with 3 spp.
* or a new adventive sp. ...

If we can eliminate some of these genera/spp., I'll gladly dig deeper.
