It could be, although it looks like it could be a false widow.

I agree that it may be a false widow, Steatoda grossa. They have multiple dimples on the brown abdomen and a gold arc in the “shoulder” area. These kill black widows. I don’t think it is a black widow, the markings are much more like the false widow.
