Moved
Moved from Crabronidae.

ID to genus level by Dr. Matthias Buck.

"It is a Belomicrus, noting modified metanotum and tubercles behind eyes."
The modified metanotum looks like it is part of her wings in these images. It's hard to see in between the wings. (white with a semitransparent rim) See another example of it here.

Moved from ID Request.

I sent a message to some of our experts. Let's hope that they can tell us more about her.

Female
Tarsal-rake spines on fore-legs = ♀
6 abdominal segments = ♀
Can you count the antennae segments?
I'm pretty sure that this is a female, but I have never seen such an old-ball, with those two (large) tubercles on the back of the head.
Please tell us how you found her, because that information may be important.

She was caught in a white pan
She was caught in a white pan trap with some linalool scent added. Common flowering plants in the area were California Buckwheat (Eriogonum fasciculatum) and San Diego Wirelettuce (Stephanomeria diegensis). I also thought those large tubercles were quite strange and may help with ID.

OK
If you are collecting specimens in California, I suggest that you contact Dr. Douglas Yanega. I'm sure that he would love to help you with some of your identifications. (like this one) Alternatively, you could send your specimens to BOLD for a DNA test.
