Sweetheart Spider

I found this minute spider on my sweetheart rose when I was photographing it. I hadn't seen the spider until then! It's a pretty little spider and I think is a jumping spider, called Trite Mustilini. I'm open to any correction though!

Thanks for the help with identifying yesterday's flower. I think it's a 
Nuttalanthas canadensis or blue toadflax. Such a pretty little flower.
