Xysticus cristatus fem. ?

Well, I would agree with Xysticus sp.

But, like so many uncooperative spiders, the colouration is variable and there are several similar species. X. kochi for example.

In some ways your specimen resembles X. erraticus although the central darker coloured triangle on the carapace ends with a well defined dark line which is typical of X. cristatus, etc.

So I wouldn't put any money on any of them, although details of the habitat may alter the odds slightly.
