I can see why you went for intricarius, as this is a very hairy specimen of pertinax. Spring specimens are often quite hairy, though. intricarius has black legs with clear pale bases to the tibiae, and is more hairy than this one.

Many thanks. I can now see the quite subtle differences between this and a 'genuine' E intricarius I took last year. (Richard (Bugman) Jones of BBC Wildlife magazine ID'd the latter, and luckily introduced me to Ispot.)
