Hmm. Actually I researched some more and found that Lynette was most likely correct with her original Eriophora edax suggestion. I found that there is a color/pattern variation in edax that does match this spider. Also, it appears that E. edax really is the only Eriophora in Arizona according to all the papers I read through. Check out the #43 diagram for E. edax on page 297 of one of Levi's papers: http://www.bio-nica.info/Biblioteca/Levi1970Araneidae.pdf

Does anybody agree that this is in fact E. edax based on that paper/diagram?

 
Good find!
I read it and I totally agree.

 
Neat!
Since you agree, I'll just move it to edax I guess. I haven't been very active on Bug Guide lately, I know... and the last week or so, I've been trying to get caught up at the SpiderID site, which is actually what led me to the Eriophora section here. Someone had an atypical variation of a ravilla and I did some reading through Levi's papers to find out more. I ended up adding some info on the variations of ravilla on the info page here and just got a little caught up in trying to place all the other Eriophora to species. So that's the long story of how I wound up here! Haha. (I thought you might wonder why I hadn't even been around on the site lately and then out of the blue want to talk about some Eriophora.) :)

 
Me too,
That's kind of how I end up at certain images most of the time too. One thing leads to another. I'm glad you found that, it's a good reference. I already added it to the info page.

This specimen's color pattern, with the white narrow line, fits Levi's description of a variation of the females of Eriophora ravilla.

Eriophora edax?
I found one source that lists this sp. for AZ.

 
No
based on images found here, I don't know if this is edax.
