Staphylinus dimidiaticornis: scutellum colour?

As soon as I'd clicked, I remembered S. erythropterus. There's difference in pubescence which I doubt would show on the photograph, but it has the scutellum white with pubesence, whereas the scutellum of S. dimidiaticornis and S. caesarea is black. I don't think the scutellum of yours is pale, is it?

Like the other

Like the other 'dimidiaticornis' at this is erythropterus, and for the same reason.

Yes, I believe so but I have not shifted Likely.
It's not an easy call for someone way outside their comfort Zone (I am) but I am quite happy with what I see.
A decent photo and some good interactive Comments.
Where are the entomologists?
