Compare your pic and
Amaurobius fenestralis - Wildlife Photography with my recent post, and I think that you will see what I am thinking. Not a better man, but the L. Sclopetarius is so distinctive.
The biggest difference in the biology of the two is the type of silk produced, Amaurobius sp all produce sticky cribellate silk, also called hackle-band silk, but L. sclop. has an orb web, and spends most of it's time in that web, in the centre. Have a look if you have the time, and let me know what you think.
