Thread-waisted Wasp Segmented (ventral) - Prionyx - male

Thread-waisted Wasp Segmented (ventral) - Prionyx - Male
Tonopah Desert, Maricopa County, Arizona, USA
May 10, 2015
Size: 22mm
These are images of a Thread-waisted Wasp, that I believe is a male Prionyx atratus or Prionyx subatratus. I'm not sure that you can tell them apart without a DNA test.

Characters:
1) - The wing's submarginal cells are difficult to trace on these wasps and yet sometimes they can be used to verify a genus level ID.
2) - He has a globular shaped abdomen, with 7 segments.
3) - One key feature that I have noticed on several images in this genus (only) is a brown stripe along the inner-ventral margin of the hind tibia.
4) - There are thin, reddish stripes of lightened pigmentation on his foreleg femur's mid-ventral and even thinner stripes on the forward or basal side of his mid & hind coxa & trochanters.
5) - The clypeus has a semicircular depression on the mid-ventral edge & a matching suture line above that. Also some slightly reddish coloration can be seen on his hairy face.
I have posted the female that I filmed later on. Her images can be found here: ♀

Would agree if from the eastern USA
But in AZ it may be another species. What about subatratus?

 
FYI - from CAS website
Here is the CAS info for that species, for my own reference or anyone else:
Copied from here: (page 28) CAS Website Catalog of Sphecidae - genus Prionyx

"49. subatratus (R. Bohart)

Not sure yet
I cannot rule it out and I need more information.
The CAS website has a listing for a Holotype of Priononyx subatrata. I'm not sure if they spelled it wrong and didn't notice. Here is the link: CAS listing for Priononyx subatrata (Holotype) That is a specimen that I would like to see.
