Comments & ID Thoughts
My guess is that this species is (Latrodectus hasselti) or the Redback Spider. There is a red hour glass shape on the ventral abdomen and long red stripe down the dorsal part of the abdomen. This is my best guess and there is a serious complication with this identification as it is stated to be native to Australia and New Zealand. This spider and subsequent photo are found and taken in Idaho, United States. I would like to know why there is a red stripe down the back if it is not in fact, Latrodectus hasselti.
It was found in a cool and damp corner next to my daughter's window. It was found in a very tough and sticky web.
