Crab Spider (Mecaphesa, Thomisidae)

I'm pretty sure this is another Crab Spider (Thomisidae) in the genus Mecaphesa. The yellow color is unusual but not unheard of - see this photo. I believe these spiders are color-shifters, but it's interesting that I found this one on leaves of Eastwood Manzanita (Arctostaphylos glandulosa ssp. mollis, Ericaceae) with nothing yellow in sight. Go figure. (San Marcos Pass, 27 February 2018)
