Not sure where to place this. My guess is Eumeninae.

Pterocheilus sp. - female (Eumeninae)
Large tegulae, without a notch in front of the parategulae, are a hallmark for this genus. Also diagnostic are the "feathery", often three -segmented, labial palps: the hairs of the right one are visible, behind the right mandible, on the thrid picture, the one showing the insect's face.
There are many species of this genus in the arid South West. Some authors recognize several genera, like Hemipterochilus or Cephalochilus.

Pterocheilus, Eumeninae
Thanks, Richard, also for pointing out the diagnostic characters visible in the images. Pterocheilus - 'winged lip'; I wonder what this name refers to. I noticed the hairs on the right mandible and included that photo in case it might be helpful.
The tegulae (forgive my basic question) must be the yellow, scalelike coverings at the base of the wings?
Richard, I just submitted a photo of a similar looking wasp. What do you think, same genus? (See here: 1)

And thank you
For your excellent photography and wealth of information. You probably are more qualified to be an editor than I, maybe you ought to talk to the web master.
