So I have been doing some digging and have come to find out that the Kukulcania hibernalis is indeed much larger than the Kukulcania arizonica! The K. arizonica averages 13mm (excluding legs) for females and the K. hibernalis averages 19mm (excluding legs) for females. Also the K. hibernalis reaches a 2.5" legspan whereas the K. arizonica reaches only about 1.75" - 2" legspan for larger adults. Also, female K. hibernalis often has dusky patches on the carapace whereas K. arizonica does not and is uniform in color.
The only reason I have looked into this is because of my very large female has started to intrigue me even further and I have decided to delve into further research of the species.
That is about all I have come to find so far!
What
I believe(no proof in writing) that Kuks can also breed before their final molt or will continue to molt after maturity.

Thanks for posting this. I'd been wondering if mine was a arizonica or hibernalis. I now know that she's an arizonica. Again, thanks.
