Definitely in this genus, but I don't believe this species has a red abdomen or occurs in CA. Check out this link for a literature-based listing of jumping spiders in CA:

Thanks kueda's for your help. I always want to try to get down to the species if possible. I've come up with 3 species : arizonesis,clarus,or johnsoni but I can't find any photos yet ?

BugGuide has photos of all three:

but as with all tiny arthropods, and especially with spiders, it may simply be impossible to get to species based on what you can see in this photo.

I would go with the P. johnsoni primarily because it looks very similar and its the most commonly encountered jumping spider in the area. I love these spider's eyes which I'm pretty sure they have situated all around their head so that they can make their precise bounds. You can almost see them calculating their moves before they leap.

I lean towards P.johnsoni also. But the photo quality isn't good enough.
