Definitely Steatoda sp
I think it's safe to move this to Steatoda. That is definitely the genus. It's probably either a borealis or a grossa, more likely the former. The 'collar' on the anterodorsal portion of a grossa abdomen is solid and straight...whereas this one has a 'spike' in the center of the collar. That makes me think more likely borealis. Those are just my observations, though. If you move it at all, only go to genus.

Theridiidae
Cobweb Weaver. Possibly something from Steatoda.
