H. hiemalis
Yeah, under the scope the epigynum is a good match for H. hiemalis.

Pretty spider.

Joe, thanks for all the help. Haplodrassus hiemalis looks to be what this girl is.

Joe, the UNH website lists H. bicornis, hiemalis and signifer.

Maybe it is H. hiemalis after all. Look how similar the ventral epigynum is to this photo:

It doesn't match any of those well. Strangely, your ventral photo of the epigynum is almost a perfect match for the **dorsal** drawing of the H. hiemalis epigynum.

Haplodrassus cf eunis
I spent some time trying to key this out using just the epigynum. I'm convinced that it is Haplodryssus (Gnaphosidae). It is probably Haplodrassus eunis. The text of the key in Platnick Shadab 1975b (SONA) takes me straight to H. eunis. However, the only illustrations I can find for the epigynum aren't a perfect match. Two illustrations are available, but one appears to be a redrawing of the other. They certainly don't look like two different specimens to me, so I don't think the drawings represent the variety well.

I'd have pretty high confidence with H. eunis then, if it weren't for the fact that H. eunis (in these revisions) is only reported for the western states and central and western canada, not for the northeastern U.S., where this specimen was found. I haven't attempted to pull up recent checklists for the region, though.
