False black widow ?
Yes, I think so. Of the Steatoda spiders, they’re quite robust ( hence “grossa”) and dark. She’s a mighty hunter. She can kill cockroaches, Black Widows, and many other bugs.
I don’t think you can rule out Steatoda bipunctata for this one….it has the line….the 4 divots on its back…and there is a bit of banding on its legs if you zoom in on them….they are an accidental import from Europe and bugguide lists New Brunswick as a location they have shown up in. It also says they tend to displace the native Steatoda borealis when they show up in a spot.

That might be it, Rabbit Hutch Spider
The “face” on the back looks matching
Definitely Steatoda genus. Hard to be certain of the species ID…they are all harmless though…the native Steatoda borialis is also very similar…but it does get out competed by the European import…
