Zygiella is what we
would have suggested

 
Zygiella atrica
I'll match that and raise you: Zygiella atrica

In Steve's great close-up one can easily see that the palpal tibia is much longer than the cymbium (the broadened shell-like tarsus of the pedipalp that supports the palpal bulb -- the back part of the "boxing glove") and this then keys out to Z. atrica (Dondale et al, 2003).

One can also faintly see the shape of the paracymbium in the image, and the dorsal view also matches well (as does the north-east seaboard location).

Oops!
I think the individual in the lateral views are of a different individual than those showing the dorsal views. The abdominal patterns don't seem to match. Umm, and I'm not even sure they're the same gender. It looks like I shot three individuals in the span of about ten minutes that night. The third one, I posted I posted last Spring here.

Should I unlink them and put the dorsal views back into Zygiella? Are the dorsal views in fact of a female? Sorry for the mess.

 
Yes, I see what you mean. The
Yes, I see what you mean. The dorsal views do appear to be of a female; the view of the carapace shows one in the process of having lunch. In any event, they are all clearly Zygiella and the dorsal pattern fits Z. atrica. You might want to split them up here so as to get the gender straight, but otherwise I see no reason to not leave them all in Z. atrica (specimens have been placed here on far less).

Done
The images of the male are now here:
