Comments & ID Thoughts

What kind of spider is this? Doing a search it appeared as if it might be a False Black Widow but that appears to be a UK species only.

Hi, it looks like Steatoda nobilis, a Noble Widow. It is also called a Skull Spider, which is helpful for identifying the mark on the abdomen. It is part of the group commonly called False Widows. They are cobweavers in family Theridiidae. The one specifically called False Black Widow, Steatoda grossa is present in USA.
