Moved
Hard to say due to the angle and resolution. Cannot tell if the scutellum is really raised or it's an illusion due to angle and lighting. My guess is it's A livens or A. mellillus. Getting species names on Aeolus is very hard from images were multiple species occur due to nuances (pronotal shape, scutellum shape, number of carinae on hind angles, etc.)

Moved from ID Request.

Aeolus
A click beetle in the Genus Aeolus, compare with Aeolus scutellatus or Aeolus mellillus .

Perhaps A livens?
What about Aeolus livens?

Scutellum
The image is not quite clear, but the scutellum seems to be raised and reflecting light, so I would vote against A. livens.
I am not an expert though, Blaine will eventually chime in.
