So is this just in P.audax or P.regius as well?

I can only speak for audax as they are what I raise.So is this just in P.audax or P.regius as well?
Thanks. I think regius can be sexed on the chelicerae then.I can only speak for audax as they are what I raise.
P. regius are far easier to sex because of obvious sexual dimorphism and able to sex much younger than audax. But like I've said, I've seen some friends have atypical individuals! Of course, that's the exception rather than the rule. I'd just prefer to look for the goods. It's easier for me. Good talking with you all.Thanks. I think regius can be sexed on the chelicerae then.
Thank you for the information.
If she was wild-caught in Colorado, she is likely not Phidippus regius, as they are primarily found in the southeast.I've been doing some research this morning, and I'm now second guessing if she was an audax or a regius. Unfortunately, I have no pictures clear enough that I think would help you identify. What are the main difference between the two? Judging by pics on the Web, they both look very similar.
Wow thank you for that explanation, that was very helpful and exactly what I needed!If she was wild-caught in Colorado, she is likely not Phidippus regius, as they are primarily found in the southeast.
A formal description of how to distinguish between the two species.
One quick method is to look for iridescent scales and matte (without gloss) black patches on the abdomen. This feature is present in P. audax (left) but not P. regius (right):

It could have lost a palp (or a leg) as a result of a bad molt or an attack by a predator.Ever heard of one of these guys missing a pedipalp? Because I never noticed it before but it appears he's missing one.
Yeah it was interesting. All the legs were there, just no palp.It could have lost a palp (or a leg) as a result of a bad molt or an attack by a predator.
Males of some spider species may also lose a palp during mating!Yeah it was interesting. All the legs were there, just no palp.
I wouldn't have guessed that, very interesting! Love learning little tid bis like that.Males of some spider species may also lose a palp during mating!
Kind of, but it's just not that simple. Female regius very often have purple/pink where as males have green/blue/teal. However, there have been regius females documented with green and there have been (as I posted a pic on this thread somewhere back,) female audax with purple. The question wasn't differentiating between audax and regius. What the whole question was was identifying sex by the color of the chelicerae in the op's Phidippus audax. In audax it's certainly not an identifier and in regius, well, I just don't feel it's as reliable as checking gender the good ol' fashioned way. That being said, I don't think I've ever seen a male regius with pink jaws, but have seen females with green- so that's enough for me say I wouldn't sex on jaws alone. Just my personal opinion.Correct me if I'm wrong but isn't regius bigger than audax? And doesn't regius have purple iridescence whereas audax has a more green/blue iridescence?
