The "bryantae form" is term that G.B. Edwards used in an e-mail to me about the one that I had collected in TN. The biology of these spiders, the palpal organs especially, is the same as other "southern" audax. The term "form" refers to the pattern of colored scales on the abdomen. Also, the bryantaes that I have seen have all had the carapace markings as well. However the question has been raised on creating sub-species for "northern" and "southern" audax, since the palpal organs of those found in the two regions of N. America have slight differences. Entire books can be written on this subject, so I'll stop there.
As far as being able to identify them to form, it's very easy to see why those who studied this species in the past misidentified them so often. I really have no easy answer for you except that by looking at the photos that have been and will be posted, you can see all of the variation in this species. Jeff Hollenbeck has some great literature on "unusual audax of Florida". There really hasn't been much work done on these spiders other than those papers.

for a while. We do have about 75 images that have been placed on the audax page and were just wondering if something could be done to make them more informative. Maybe Jeff will chime in with his thoughts.
