Color morphs in Phidippus regius

Back in time there were three established morphs in Florida alone, with substantial color and size variations,

Quoting @xenesthis, at the end of an old thread in 2009:
http://arachnoboards.com/threads/huge-p-audax.168205/

'P. regius has three distinct color morphs. The black morph is in North FL. The gray morph is in central FL and the orange morph is in south FL. In central FL, all three can be found, but the gray morph represented the most.'

However Phidippus regius has a wide distribution and can be found beyong North America, well across the Caribean and most of West Indies, including Cuba, with very colorful morphs there indeed. For instance the "Soroa" variant, has a vivid orange and black abdomen in females. Do you know any other morphs?

How do you tell the difference between P. audax and P. regius black morphs?

*Now I see, regius has coloration under the primary set of eyes and audax has significantly less hair on the carapace.

It is both interesting, and unfortunate, to see the lack of genetic analyses on Phidippus. All data seems relatively old and based on morphometric studies (although there is nothing inherently wrong with these works). I have a background in mammalian studies, so it does seem rather stark in comparison. If only people knew the complexity of jumping spider behavior!

I will be watching this thread, as I wonder if we are dealing with subspecies, cryptic species and/or large superspecies, but perhaps more fine-tuned than the Phidippus otiosus group designation. It would be great for some genetic studies on one of the Phidippus groups to determine the genetic distance between members of these "groups" based on morphometrics.

Here’s a weird case~ Phidippus octopuctatis is not normally found in Washington, but there were sitings of a mysterious “WA P. octopuctatus”

Not sure if this is significant but the majority of the time, the iridescence of my male is blue. If I recall, most of P. regius males display an iridescent green, with blue hints. I also tried a UV light to see if there was additional patterning augmented or made .

Found a more recent revision on Phidippus genus, with distribution maps included. By Edwards, 2004

P. regius and otiosus share roughly the same areas in Florida, but NOT in Caribean Bahamas and Cuba.
In fact the Cuban / Bahamas phidippus does not normally yield fertile eggsacks with the mainland (References breeders here in UK). So one wonders if in fact the caribean morphs represent in fact different subspecies, rather than simply locality.

The next closest to P.regius is P.diantus according to cladistics, end of the paper

Salticid phylogenetics with relation to demographics dates a common ancestor between american, european and asian radiations to 47-57 my. Young?

The salticid genus Sassacus (Dendryphantinae) is the closest to Phidippus, according to very recent phylogenetic revision, extending from Panama to Canada, with a high representation in Mexico, Brazil and US (S. cyaneus, S. papenhoei). Maybe giving clues about the origins of this branch of salticids.

Could you tell me where you got this info? What coloration under the eyes are you talking about?


Great thread, I would love to see more studies on morphs / subspecies / species of Phiddipus too...

That's a great question... what the heck was I talking about?! I was making poor observations and drawing even worse conclusions on a subject that I’m still learning about. Please ignore my ignorance and thank you for bringing it to my attention.

I wasn't actually pointing out the mistake, but trying to learn how to differentiate them :) So what you said is not true?

Not true at all. I was confusing myself and you as well apparently, sorry about that. I still can't tell the difference :rofl:. Now I have to wonder, are the pictures out there even correct?

*I've never actually seen a black morph P. regius with my own eyes, so there's that variable to.

I think audax has more “texture” to the abdomen than regius. When you look at an audax female, that abdomen is not completely uniformly black. You can see there’s a reflective iridescent area and a black velvety marking. I think that is what distinguishes audax from black regius. regius also has those “lashes” which I forgot what is the scientific word form them called.
