I believe this to be a ground spider. Is this so?

Moved from Antmimics and Ground Sac Spiders.
The genera Meriola and Trachelas were transferred to the new family Trachelidae.(1)(2)

Moved from ID Request. I think the family is right. We'll probably have to learn more to figure out species.

I would suggest family Corinnidae. Maybe Meriola? Steve Lew's list has M. californica and M. decepta. The banding on the legs look something like an image of M. californica we have in the guide:

The abdomen pattern is absent or very faint here.

Trachelas also looks similar, but Steve's list only has T. pacificus, and I can't find any images of that with banding.

Nice find, let's see what others think!

I just stumbled across a T. pacificus with banding but suspect it may be a misfiled Meriola, what do you think? Edit: Oh, I see that suggestion was from Rod Crawford. Don't know what to think now.

Good find. I would have guessed Meriola too, but if Rod thinks it's T. pacificus then separating the genuses could be tricky. I wonder what the distinctive features he saw in it were.

We have to keep in mind that
Rod bases his IDs on experience with spiders he knows from WA. He's told me many times that when it's a spider outside of WA we need to weigh his comments as a suggestion. I'd say more research is needed.

My first thought was Trachelas. There aren't many Meriolas for me to compare to, but the posturing and a subtle thing I noticed is that back legs look lighter than the front like they do in Trachelas and I don't notice that in the Meriolas we have. It's interesting whatever it is.

You could be right, though I think the back legs can be lighter in Meriola too:

It's a dead spider, but the front legs seem significantly darker red.

I just found an image of Meriola decepta:
the banding is much weaker, but the abdomen looks close...

OK, I see it on that one. Meriola decepta looks a lot like Trachelas.
