spider sf bay area, under awning of house, nocturnal) - Steatoda nobilis

Moved

Moved from Cobweb Spiders. I think it looks just like S. nobilis, and with records already popping up in Orange, Ventura, and Monterey counties, I don't think Santa Clara would be much of a stretch. It seems to be a fast spreading species, even in other countries, and with its CA origin speculated to have been the naval base at Port Hueneme(1), maybe it could have had multiple points of entry?
I did go through the other species of Steatoda found in CA, though, just to make sure we don't have any look-alikes with the same abdominal pattern; couldn't find any, but S. palomara is somewhat similar (yet still different enough to tell apart).

Steatoda / Asagena ?

I looked through Gertsch 1960 and didn't see a visual match to any of the patterns provided. I looked through Levi 1962 and didn't see anything similar. I looked through Levi 1957 and didn't see a visual match. It's becoming an interesting spider to me and I'd like to see more images of it if possible.

Nice find. This is a cobweb weaver of some kind. It might be Asagena, but I'll have to do more research before I can guess further. It is not one of our medically significant spiders.

steodata nobilis?

I considered that. That species established in Ventura County, but Santa Clara Co. is pretty far North. I would need to look at my references before I could guess species with any certainty. I just don't have time to do that right now. Perhaps one of the other spider people will have time before me, but we will get to it eventually. =]
