About 8 mm long found under cow pat seven days old.
No interactions present.
It is fimetarius sens. lat. Unfortunately it was split in 2001. Opinions differ on how easy they are to separate. Originally, it required dissection and injection of acetyl choline, but others think you can separate them just on colour. There is also a head character. I either can't tell the difference, or all my specimens are one segregate. I can send you a paper on it if you let me have your e-mail.

Having checked the angle between temples and clypeus around the eyes(162 degrees), this specimen conforms to that recorded for A. fimetarius rather than an angle of about 138 degrees for A. pedellus.
The disc of the pronotum is sparsely punctured, also pointing toward A. fimitarius.
