Araneus pima=illaudatus, Araneus illaudatus=abigeatus

On page 137 of the bulletin titled "The Diadematus Group of the Orb-Weaver Genus North of Mexico" by Levi, there is an image of Araneus pima. I was struck by how similar it looks to A. gemmoides. Sure enough it appears to be the result of cross breeding between gemmoides and gemma. I looked through quite a few images in the guide mostly from CA, NM & AZ because I know it's been collected there. I found a few images that closely match the picture in the bulletin of A pima. See


In the bulletin the specimen has two white markings in front of the humps. These white markings are more straight across than diagonal. Brian has already named his Pima, which I can't disagree with. He also has a couple images labeled A. pima on the www.americanarachnology.org site.

Why is the american arachnology site still using pima? Should we moved these images to illaudatus? Levi says that pima and illaudatus have quite different epigynes and "However, owing to the great size difference and abdominal pattern difference, I remained stubbornly unconvinced that they could belong to the same species until spiderlings from an egg-sac raised by P. Witt grew up into female A. pima and male A. illaudatus. This persuaded me but raised some new questions, as the hand-reared males are larger, the females smaller, than in wild populations". Full text can be seen here.

This PDF article continues to name A. abigeatus as a new species which was previously called A. illaudatus. So let me try to get this straight. The old illaudatus is the new abigeatus. The old pima is the new illaudatus? So the 1971 descriptions of illaudatus are acutally abigeatus and the 1971 descriptions for pima are illaudatus? Do I have this straight?

Sort of...
This is from Platnick. Stare at it for awhile and see if it helps. That's my usual method :-).

mf abigeatus Levi, 1975....................USA [urn:lsid:amnh.org:spidersp:014654]
   A. illaudatus Levi, 1971a: 176, f. 233-237 (f, misidentified).
   A. a. Levi, 1975c: 269, f. 5-11 (Dmf).

mf illaudatus (Gertsch & Mulaik, 1936)....................USA [urn:lsid:amnh.org:spidersp:014943]
   Aranea illaudata Gertsch & Mulaik, 1936b: 19, f. 36-37 (Dm).
   Aranea illaudata Archer, 1951a: 36, f. 74 (m, not f, f. 67=A. nordmanni).
   A. pima Levi, 1971a: 176, f. 218-232 (Dmf).
   A. i. Levi, 1970: 108, f. 14-15, 18-19 (mf).
   A. i. Levi, 1971a: 176, f. 238-240 (m, not f, f. 233-237, =A. abigeatus).
   A. i. Levi, 1975c: 268, f. 3-4 (m, S).
   A. i. Roth, 1985: B6-5, f. 49 (f).


The description page number and image numbers listed might help to sort this mess out.

A. abigeatus and illaudatus are currently valid species, so I have no idea why A. pima would be in any current usage.

I couldn't find the Levi, 1970 article, but it's only four pages. The 1971a listed is the MCZ Bulletin, which I think you got from me, and 1975c is the Psyche article.

 
You're right Platnick does help
Images 218-232 in the 1971 bulletin are labeled pima, so I'll change those to illaudatus, and images 233-237 (female) are labeled illaudatus and I'll change those to abigeatus, but images 238-240 (male) remain illaudatus.
