Most likely ...
Tigrosa annexa.

 
Thanks
so much for your help. I didn't realize there were different color appearances of Tigrosa annexa. But then… I am so uneducated when it comes to spiders. And, I would guess that the digestive juices of a cane toad and alcohol distort the original spider colors.

This is quite a project I'm working on as a volunteer at the Conservancy of SW Florida. The science staff have collected several hundred cane toads and I'm analyzing stomach contents. So far, I've examined 30 stomachs and found several species of spiders, at least 2 species of millipedes, 1 species of centipede, 2 species of snails, 1 species of cockroach, 1 species of earwig, 2 species of fly maggots, 1 species of giant water bug, 1 species of leaf-footed bug, 1 species of burrowing bug, 4 species of ants, 1 species of ichneumon wasp, 2 species of caterpillars, 4 species of ground beetles, 1 species of leaf beetle, 1 species of snout beetle, 1 species of predaceous diving beetle, 3 species of click beetles, 3 species of scarab beetles, 1 species of rove beetle, 1 species of darkling beetle, 7 beetle species yet to be identified, an earthworm species, a mole cricket species, 1 species of lizard, 1 partially digested frog species, and 1 unknown species of mammal (fur only). These toads are extremely invasive in yards and golf courses in Florida, and poisonous to dogs.

Again, Laura, thank you so much for your willingness to offer your expertise.


 
You’re welcome ...
being half digested makes these challenging. And yes, I think the color is off because it was half digested. The color fades when they’ve been in alcohol for a while too.
