This is is a northern black widow, Latrodectus variolus, a different species from our southern variety, Latrodectus mactans. Here is what Bugguide says about it:
"For the northern black widow, the hourglass is distinct, but is broken(1) (whereas the southern black widow's hourglass is complete) and typically there is a row of red spots down the middle of the back and possibly some diagonal whitish bands on each side; the bands are typically observed on the younger, more juvenile widows."

Eventually I was out voted in releasing them and they stayed sealed up for a year to ensure they were neutralized. I felt better knowing that a female will have 9 to 15 eggs sacs with 100-900 eggs apiece over her lifetime so she probably didn't miss these.
