Spider ID please

Hi all. I posted this pic before but had no replies so am hoping someone may have missed it and can help. Approx 12mm, I found it on my back wall one night. Possible Drassodes?

Not an expert but........I think......
I had one a while ago, in the lounge for a few weeks, then it migrated behind a wardrobe.
It's the Mouse Spider - Scotophaeus blackwalli there are few in the Spider Gallery Message - Wildlife Photography including mine.

Ps On second thoughts and looking up (Drassodes) That looks more likely.

Well Drassodes was my guess but I can see similarities with S.blackwalli

The rather hairless legs does superficially look like Drassodes but Scotophaeus is more of a 'house spider'. Although I think you meant an outside wall.

Clubionidae sp. is also possible, and there are plenty of almost identical versions to choose from. They are also more at home outside and away from buildings, but we have had indoor sightings previously.

To be honest I discounted Clubiona due to the size, this specimen was around the size of a large Tegenaria when legspan is included in the measurements. I was on the understanding Clubiona were rather smaller?

Also I think we can narrow it down, as this does appear to be a six-eyed spider.

The Gnaphosidae family are eight eyed spiders. The only British species having six eyes are the Oonopidae, Dysderidae and Segestriidae families.
The posterior median eyes (rear middle pair) are good for Gnaphosidae (a pic from directly above should hopefully show the row of eyes being recurved) and rule out Scotophaeus, though a view directly from above, below and one of the spinnerets would have proven more decisive as to which of the family it was. Drassodes is a good possibility though.

My apologies all, I (for some unknown reason) thought Drassodes was a six-eyed spider genus?? Dont know why I thought that now.

I am happy to close the case as a more than likely Drassodes umless anyone can give a good argument against it. Many thanks all for your help, I am learning alot from the help given by you all

Sorry to reopen an old thread. But having studied these pics now, the eye arrangement appears to suggest Scotophaeus blackwalli even though the colour ation seems awfully light, and it does not seem as 'hairy'?

I can't increase magnification around the eyes on the other halfs pc, but the front 'corners' of the carapace appear to be indicative of Drassodes (Scotophaeus being marginally more rounded), as are the darkened chelicerae. The abdomen is also broader around the middle section of the length as opposed to a more streamline abdomen of Scotophaeus.
