Well... heres a side on anyway (not great quality I'm afraid).
I assume this is a female Pseudeuophrys lanigera (fore legs not dark), but would very much like a second (more knowledgeable) opinion.
Like I said (although the photo is at home at present), I do have a top down shot - looks like a scull on the back to my weird imagination - a very wobbly, faded skull.
Length no more than 4mm (excluding legs).
I'll try to upload the top down shot tomorrow if needed....
Thanks
Doug
