You can see the radial cell is not expanded and oval, but rather trapezoidal. Combined with the node halfway along the wing firmly places this in Okanagana. Veination is the best way to separate these genera aside from song.

Moved from Tettigadinae.

Moved from Okanagana.

ADDENDUM: As Dr. Hamilton mentions, there are other Genera which strongly resemble Okanagana, further complicating identification (esp. with regards to images).

Although I cannot myself make out the wing character in this particular image to which Dr. Hamilton refers - thickened crossvein at the tip of the clavus, this trait would indicate that this cicada is indeed Clidophleps....However, when I first reviewed this image, the margin of the pronotum looked to be strongly flanged & less constricted, esp. as visible along the right side between the eye and mesonotum, thus leading me to conclude this was an Okanagana.

Please refer to the following:
Genus Clidophleps
Genus Okanagana
Genus Okanagodes

You can barely make out the thickened crossvein at the tip of the clavus (halfway down the midline of the wings) that is characteristic of this genus; but the parallel-sided prothorax that seems to be squeezing the thorax in the middle is obvious.

Sorry, I don't know this species. It isn't the common C. vagans, which is boldly striped in black and yellow. Possibly C. distanti, which has obscure pale markings.

Moved from ID Request.

Sorry, I'm not so well acquainted with the western fauna, especially the Okanagana species (and allies). There are a number of these in the western US and many are very similar in appearance.
