Clubiona female? - Hesperocranum rothi - female

Clubiona female? - Hesperocranum rothi - Female
Lassen National Forest, Warner Creek Campground, Plumas County, California, USA
May 18, 2015
Size: 3.5 mm
I beat this little spider from a fallen pine cone. It seems to be a clubionid and Clubiona is the only genus in CA, but I'm having trouble finding a good match in Edwards 1958 or Dondale and Redner - have I screwed up the genus or even family?? :) If it is Clubiona, it looks like maybe an epigynum dissection or clove oil immersion might help...

Added photo -
of ventral tibia I that seems to show the features of Hesperocranum. I actually looked for this feature when I first keyed it out and missed it... Thanks Laura! I can see if Darrell is willing to confirm the ID later this week, but I think it's safe to move? I'd be happy to make the guide page, but I'll give you first dibs at the honor! :)

Thanks, I made the genus ...
you can make the species page when you're ready to move it. :)

You're better with ...
technical terminology than I am, take a look at Hesperocranum rothi. The diagram that I'm seeing for the epigynum on that one looks like it might be a possibility (Ubick & Platnick, 1991).

Wow -
nice find Laura - let me double-check and clear the epigynum (next day or two), but I'll bet you found it... :)

Nice find ...
to you too!

It's easy -
to collect spiders, but hard to identify them!! :) I'm somewhat mollified that this genus was thought to be in the Clubionidae by Roth initially - these families can be hard and have been rearranged a lot lately...
