[GRH]

There are a couple of genera with patches of gold hairs on the abdomen - Platydracus and Staphylinus (all lovely beasties!). I believe I can just see some gold hairs on the head (do you have a better head shot?), and this, along with the gold hairs on the pronotum, rounded hind-angles of the pronotum and size would make this Staphylinus species (20mm too big for Platydracus). However, S. erythropterus does not have gold hairs on the pronotum, which would make this Staphylinus caesareus, which isn't nearly as rare as some texts say it is! (Admittedly these texts are old, so it may just have increased over the years).
