Hoplitis? - Tachytes - male

Hoplitis? - Tachytes - Male
Lake Roosevelt, Ferry County, Washington, USA
August 17, 2007
Size: 5/8 in +-
This looked to me like a good match for an image of Hoplitis in my reference. This bee/wasp had been foraging in snow buckwheat, Eriogonum niveum, and tended to hide or fly away when approached.

Male
The spots on the thorax are not mites. That looks like sand grains. -- 11 flagellomeres = ♂

Crabronidae?
Tribe Larrini, perhaps something related to Tachysphex ? At least that's what this reminds me of.
However, I'd wait for more competent advice.

Larrini
I'm not sure of the genus

I suggest Tachytes
Because color pattern (and comound eye color too) is virtually identical to our two own species here in Western Alps. Moreover, 5/8 inch is a bit large for an "average" Tachysphex.

Tachytes
Sand loving wasp definitely fits the locale. Thanks much!

Larrini
I'll see if I can't find another angle. Abdomen is amazingly similar to that of a honey bee. Zooming in all the way on this photo, it appears this one is carrying mites.

Larrini
but I do not think it is a Tachysphex
