Hmm, good eye. Looking at Platnick 1974, I think you might be right; I'll ask Lenny (I don't have much experience with these, either). I sometimes do check these before I post them, mainly to verify the name is current, etc, but I didn't double check the epigyne on this one (usually no need to with Lenny's stuff).
I did think the spider looked a bit different than the A. pacifica I'm used to seeing around here, actually, but thought it might have been a geographic variation in color.

My mistake! I even have a different specimen listed correctly in my guide (http://staffwww.fullcoll.edu/lvincent/spiderguide/D603.html). My image clearly matches fig. 67 in Levi 1974 so I must have associated it with pacifica which comes before the fig. numbers rather than californica which comes after the numbers. Thanks, Ken! Sorry, Mandy, more work for you.

I made the same mistake looking at the figures in that paper, too, actually! And it literally only takes a few seconds to move things here, so no extra work at all!

thanks for all your great spider images!
