Folding-Door Spider - Antrodiaetus pacificus - Male

This is spider is in genus Antrodiaetus, and i am guessing the species is pacificus, and that it is a male. Does anyone know for sure?

Since this is a male, and the first legs (which are
distinctive in male pugnax) are shown so clearly, I can pronounce it
pacificus.

Probably; Yes.
Nice find! They are actually quite common (especially males, especially at this time of year), but they are still seldom seen. Yes, it is a male, and probably A. pacificus, but there are at least two species up there if memory serves....When I lived in Portland I would visit the in-ground swimming pool in the middle of the apartment complex and find many of these had stumbled into the water.

Yes,
Rod Crawford from the Burke Museum agrees on genus. He says a microscope would need to be used to ID to species. He also mentioned that they are normally reported in September and October is late to find wandering males. I think that may be because we've had such a miserable and short summer here this year.
