In 1979 Steve Johnson made a list of all spiders known from California. He had essentially unlimited literature resources as a graduate student of B. J. Kaston, and also benefited from the expert assistance of Wendell Icenogle. I began this website as by digitizing his list as reformatted by Donald Boe in 1989, with lab support form Rosemary Gillespie and coding assistance from Chris Seidel. As time permits I update the list using more recent publications and  personal communication from skilled collectors known to me.

HUZZAHS UNTO:  All those named above, Rick Vetter, Tom Prentice, Darrell Ubick, Joe Spagna, Pierre Paquin, Marshall Hedin, Blaine Hebert,

At the moment (Jan 4 2004), it's just a checklist annotated with county records and literature ref's.  Check back soon (or not so soon) for more recent collection records.  Check back later (or much later) and there may be images, maps, keys, who knows...

Please email me with any corrections or comments, but please do not email me about whether the spider laying eggs in your brain is poisonous until you've read the disclaimer at the bottom of the page.

If you've found a spider in your yard/bathtub/laying-eggs-in-your-brain and you want to know what it is, you may find this website less helpful than you were hoping it would be. Most people who email me get this friendly and informative prefab response. It is not meant to stifle your curiosity, and you should by all means contact me if it is unsatisfying.
