Woodland Dor Beetle Anoplotrupes stercorosus

I think I must have used Mike Hackston's key to identify this, though I don't recall for sure. Looking back at my two records of this species I am pretty sure I got one of them wrong, but this one looks good I think. It was one of six dor beetles found during a moth-trapping session with the Norfolk Moth Survey group (only this one being retained for ID, but I imagine that they were all the same).
