Not P. alleni, not the wild type either.
Of course it's not P. clarkii. Hmm...what could it be?
Pics would help, but not many people have pictures of uncommon crayfish.
No, there are two questions here: (1) the identity of the red male crayfish and (2) the identity of your blue female crayfish. Like I said, the answers to (1) and (2) aren't necessarily the same.
When I mentioned wild type, I was referring to the wild type
of P. alleni (as opposed to the selectively bred blue one) while considering possible answers for (1). It's possible that a reddish form of
P. alleni exists in the wild:
(Caveat: Chris is usually quite good about these things, but the poor image quality makes it difficult to confirm the ID)
At any rate, coloration and subjective "looks like" impressions aren't surefire indications of anything, taxonomy-wise. Many species are very variable (even when we don't consider occasional mutants like the blue female you caught).
Case in point -- here's yet another reddish cray,
P. acutus, that also happens to occur in Florida:
We could go on like this for days.
A much more accurate way of identifying crayfish from the eastern part of the U.S. (including FL) would be flipping them over and photographing the gonopods (male reproductive organs), which differ between most species in predictable ways. However, this still wouldn't give us the answer to question (2) since females lack gonopods.
Do you have any specific reasons why your blue female couldn't be a
P. alleni? Do the claws look different? Is it just that it's darker than most of the ones in the aquarium trade? If the second reason's why, you should remember that the
P. alleni sold as "electric blue lobsters" are a specific captive-bred strain that won't necessary look identical to wild individuals of the same species that display mutant coloration.
Anyways, I think I've seen blue
P. alleni that look quite similar to what you have (again, a subjective judgment):
Rare blues almost certainly show up in other kinds of Florida crays, so -- once more -- I can't say for sure based on the photos.
(Blue, white, and normally-colored
P. clarkii)
Might be a good idea to ask around on crayfish-specific boards like bluecrayfish.com. Getting direct overhead shots and giving the location in Florida where you found your crays might help narrow things down.
