A Steatoda(?) caught Scutigera centipede in my basement

[Jabberjay]

A little spider I've been watching in my basement caught a Scutigera centipede in the early morning; it wasn't there last night. My best guess is a female Steatoda triangulosa, but I'm unsure. I'm also sharing because I'm really impressed at the size difference. I live in the Chicagoland area in case that helps with identification. Some of the photos are higher resolution, so check all of them.

The spider looks like Parasteatoda tepidariorum
