Herschel is right: the pattern on macquarti is reversed: yellow basally, and black apically. You say this one is smaller: divisor is about half the size of macquarti. Early spring is the right time for divisor. I am looking at a specimen of a male divisor, and it looks pretty much like the male of your pair, includng the yellow hairs on the first two pairs of legs. What I don't know is, whether there is some similar appearing Florida species that divisor might be confused with.

Thanks. That explains a lot. Although I do not have specimens, these were smaller (and more common) than the other large macquarti-type specimen. I have other photos of these guys from March, April and May, but not as good ; )
