Identification were made on another image that I incorrectly linked to this image here.

From Kevin Pfeiffer's comment:

"...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)."
