Dr. Carroll,
we have unidentified Metepeira in several locations in the guide. Can you see if you can identify any of the images? The three guide pages that need help are here:
one
two
and three.
Thanks in advance for any help you can offer.

 
Not with authority
It's necessary to look at the epigynum. I don't have enough experience with this genus to guess by the appearance.

I used

Levi, H. W. (1977b). The orb-weaver genera Metepeira, Kaira and Aculepeira in America north of Mexico (Araneae, Araneidae). Bull. Mus. comp. Zool. Harv. 148: 185-238.

Which is downloadable for free from

http://www.biodiversitylibrary.org/item/25433#79

Be advised it's a very large file, as it includes several other long articles.

I may be able to make some guesses using the illustrations in the paper.

 
Piel's Neotropical Metepeira
with many of the same species is also available Vol 157, No. 1, June 2001
