Found this one on Jan 02; approximate KL = 8mm. It was in an orb web not high above the ground. I found the white band rather striking. Not sure if it is normal, because I also saw a specimen without it (but I don't have pictures of the other one).

Hi Frits,

it seems, that this kind of color variation is not uncommon among spider of the genus Acanthepeira, for example, A. stellata. This is only my guess of course, no determination attempt.

Greetings, Uli

The genus should be right, the eye formation fits well to the diagnosis of the genus by Levi (1976). However, I think even with a genital examination it could be hard to determine the species, since Levi mentioned some interbreeding in the Southeastern States. The male genitalia seem also to be pretty similar. Would be an interesting task for a genetic investigation.

Thanks Ulrich and Tobias. I'm happy to get to genus level.
