Cristatus or similar. Some details aren't well visible and there are several similar species. This said, this technique isn't useless, this particular spider is just dark.

Ah, I thought the apophyses could help.

Some details aren't well visible.

Which ones are they? I have other photos.

Sorry Simeon but I don't understand what you mean.

1. They do but not everything is visible

2. The small tooth (lower tegular apophysis) at the base of the shovel-like prolateral protrusion, the tip of embolus etc. Latter is microscope job.

3. I was referring to the way you make photos. I don't want you to think spiders cannot be identified this way even if the Leptorchestes and this Xysticus couldn't be recognised this way.

Could that be circled the small tooth (lower tegular apophysis)?


Photos deleted in shame. :-[


Last attempt, otherwise Xysticus sp.
