Small black spider with white dots?

I live in San Diego and work at the zoo. We have to watch out for black widows, and I was afraid these might be juveniles. The same places we occasionally find widows, we often find these much smaller, smooth, black spiders with white dots. I have heard that if they're fuzzy, they're jumping spiders, but these are not fuzzy at all. These look like black widows that are smaller, lighter in color, with white dots. Maybe I should ask our entomology dept.!

Update:

Well, it looks most like the photo of the male widow. It could be that, but the dots are more like small, precise polka dots, rather than streaks, dots, and hourglass. So, idk.
