Yesterday I found a most curious Staph which I can't place.  It's too small to photograph (in fact I thought it was a mite, it got pooted by accident!) so I'm going to have to describe it.

It's about 1.4 mm long and looks rather Tachyporine-like.  I'm assuming it's a tachyporine although I could be totally wrong.  Head, pronotum and proximal abdominal segments are very dark brown and shiny. Terminal abdominal segments are a little paler brown.  It's sparsely covered with short fine setae, although there are no longer setae as you would find in Tachinus or Tachyporus.   All appendages are dark brown, antennae a little paler.

The curious thing about this beetle is that it's notably hunchbacked.  It was running round like a tiny armadillo with virtually no protruding abdominal segments.  If you imagine how an Agathidium rolls itself into a ball when you disturb it, then add a very short tapered Tachyporine tail, then it looks something like that.  The protruding abdominal segments were shorter than the pronotum and elytra combined.

The only beetle I can find that looks anything like it is Coproporus but this isn't a UK species.  Of course I'm not helped by the fact that most ID guides show a dorsal view and you lose most sense of how "high" the insect is.

Any ideas?
