P. Regius vs P. Audax?

[JayDangerVL]

I was just curious if anyone hereabouts knew the differences between the Phidippus Regius jumper and the Phidippus Audax? I know they can appear very similar, so I'd love to know how to differentiate between them if anyone would be willing to share their wisdom. Thanks in advance!

As far as I'm aware, the Regius is most commonly found in Florida. The female regius also vary in color, and can be orange, grey or black, while the males are always black.

So then, the only similarities are between the Audax and Regius males? (Visually, I mean.)
