This pretty little bug with pink eyes in on the leaf of a Brown-eyed Evening Primrose (Camissonia claviformis--Onagraceae). We saw it in sandy Coachwhip Canyon, but the same bug is on the same plant at other similar locales.

I looked up the On-line Systematic Catalog of Plant Bugs, American Museum of Natural History, for host plant. It came up with Pseudopsallus puberus, which occurs in our area and which eats several Eveningprimroses and other desert plants that grow in our area.

Two Pseudopsallus have been identified,#251774, P. anograe, also on Eveningprimroses (but our species is not mentioned) and #245349, P. angularis, on Yerba Santa.

The key in the revision could indicate P. puberus, based on the "Pronotum, at least on posterior half, with brown or orange brown cast." (But claws and male tergal processes are also considered in the key, (link given in the Pseudopsallus guide)).

However, I don't know how to identify it to genus Pseudopsallus. It has the greenish coloration, short first antennal segment and possibly the mixed dorsal vestiture of long, pale, simple setae and recumbent silvery white setae and a common host plant family all listed in the revision. But I don't know the alternatives. Any help will be much appreciated.
