I found this spider in a web above my window. Looking at pics of Steatoda grossa, it seems to be a match. But I am asking a pro, to satisfy my own curiosity.

Cobweb Spider

Hi Tim,
We believe this is one of the Cobweb Spiders in the family Theridiidae, but we cannot confirm that is is the False Widow,
Steatoda grossa, which is pictured on BugGuide.  The family also contains the notorious Widow Spiders in the genus Lactrodectus, but we feel confident that we can exclude them from the possibilities for your individual’s identity.  We believe the strongest contenders are the members of the genus Theridion, also well represented on BugGuide.  Perhaps one of our readers more skilled in spider identification will be able to provide something more definitive.

    Sort of looks like Steatoda triangulosa. I see a lot of those in Texas.

    I agree with melvisrules–it looks exactly like Steadota triangulosa.
