Some sort of Agyneta. Do you have closer photos of the epigyne?

Are you sure? The scapus looks rather narrow (rurestris doesn't vary very much). Why not affinis? Of course, I have no experience with affinis and dark palps do indeed point towards rurestris.

I see your point and this is indeed the other option. And yes, the epigyne seems rather elongated for A. rurestris. However, i do not see a retrolateral spine on Tibia I and II which A. affinis should have, while A. rurestris does not.

But this might have been obsured on the photographs. So maybe the original poster could check this character, should be able to bring this one to a definitive Id.

Thanks. I didn't know about this character. It doesn't seem to have such spines but the tibiae aren't well shown either.
