C. thalia? - Castianeira athena - female

C. thalia? - Castianeira athena - Female
Stulsaft Park, Redwood City, San Mateo County, California, USA
June 20, 2010
Size: 5-6 mm
I sifted this female corinnid from live oak leaf litter. This one is an adult female with a mature epigynum, I think - perhaps C. thalia. I'll try to work more with the Reskind paper on this one.

Does seem to fit description, etc. and definitely not C. thalia, but Reiskind characterizes this as a "Nearctic desert species".

I think you are right, but I would be curious to know what Darrel has to say, and whether he already has other specimens from the area?

Yes, would love to hear from others on this genus.
Lynette and we are going over them repeatedly and trying to make sense of the images here on BugGuide. Would love to have a more recent reference than 1969. Wouldn't worry about a couple hundred miles. Reiskind has crucigera from Arkansas and Virginia or something. Our BugGuide images are from Florida. He has descripta going as far northwest as Iowa and Wisconsin. John Sloan posted one from Alberta! A couple hundred miles off from a 1969 reference doesn't seem to be a problem.

It's not the miles, but the climate -- southern California inland valley and desert vs. the central California coast.

It's not that I think C. athena is wrong, but the significance: either the CA Academy of Sciences already has discovered this for themselves (a confirmation then for us and most likely, I think) or it would be something new that they (Darrell Ubick) might be interested in hearing about.

So, a win-win for us in any case. I'll wait to hear from Ken (being in Germany I can almost 'watch' y'all roll out of bed by time zone) or I"ll drop him a note if Ken doesn't want to.

 
Hi Kevin and J&J -
thanks for working on this spider a bit more - I probably won't get a chance to email Darrell for some time - Kevin, feel free to email him if you'd like. Best wishes.

Moved from Castianeira.

This looks like athena to us
here and Reiskind fig 275

 
Looks -
pretty good to me, FWIW - it would be a bit of a range extension from the Reiskind paper (a couple hundred miles north of their northernmost specimen, I think), but I suppose that's not unreasonable?
