Could these be related?

It's very possible they are the same genus, but I don't know if they are the same species.

Thank you

Sorry I can't be more specific. These spiders are difficult to identify, even to genus, without checking minor details on their anatomies (for instance, to know whether your spider belongs in the genus Clubiona, one thing I'd want to check is whether it has only one, and not two, prolateral spines on Femur I - unfortunately, I can't see enough detail in your pictures to tell either way.)

Going by general appearance alone isn't reliable, because spiders from separate families often resemble each other. For example, here's a spider that resembles the Clubiona canadensis (Clubionidae) shown above, and is even found in a similar habitat; yet, it is in a completely different family Orodrassus canadensis (Gnaphosidae):

I'm begining to understand what next springs images need to contain. Thanks again.
