Comments & ID Thoughts

Believe to be a false black widow spider. Looking at existing pictures there seems to be large variation in the species, if all of the pictures are confirmed.

Yes this is a false black widow you can tell by the abdonomen that it is brown unlike the black widow which is full black and has a red mark on it belly

I wouldn’t rely on color alone, there can be exceptions. This is a False Widow regardless, the pale triangles down the abdomen point to Steatoda grossa.
