Pterocheilus

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.

What species do you refer to?

your link does not not lead to anything specific!

Corrected link: https://www.inaturalist.org/observations/5075399

Also to clarify the species hasn't been identified on BG or iNat yet, so I just mean it's likely the same species to be identified. Which may require accessing museum specimens (if there are any for this species) in addition to using the keys.

this does not lead anywhere either-

but I'm quite aware how to get this identified. Have Bohart's keys to the three subgenera, but feel I need an actual specimen rather than a photo. Not a priority right now.

Okay, just to clarify:

My link does show what's presumed by identifiers including Marco Selis to be one morphospecies, based on distinctive color. That info. does lead somewhere, despite not being the final answer, and experts commonly share presumptive morphospecies info. If I'd meant I was sharing a species name I would've stated the name. This genus is difficult so species ID is often unattainable even using Bohart's keys. Those keys are good, but would be further informative if they noted in more detail which species have distinctive coloration. As you imply, the best chance of species ID will be using the keys in addition to examining museum specimens. Even then it's not certain that species ID will be readily attainable, although I believe this one should be possible to ID if labelled specimens exist. I'll stay tuned, and will also update if iNat identifiers learn the species ID later.

What you provided as link only leads to

the statement that "Your search - https://inaturalist.org/observations/5075399 - did not match any documents."
Just perusing the iNaturalist website for photos of Pterocheilus I did find a post from Kern County, CA, that looks like possibly the same species, whatever that may turn out to be.

For me it opens if entered in the url bar, even when logged out.

Oh, I used copy and paste to paste it in the url bar too. It would have been faster to use a hyperlink, so I see why you said it didn't work. Anyway it's just a similar picture. I look forward to finding out what species this is.

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)

Thanks, Beatriz,

for your friendly help.

… Hartmut Wisch, 21 May, 2006 - 8:30pm

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.

… Beatriz Moisset, 22 May, 2006 - 6:23am

Just trying

to learn the language in order to read the 'book'.
Who is web-mastering now?

… Hartmut Wisch, 22 May, 2006 - 2:59pm

The new web master

John K. VanDyk of Iowa State University.
