Confidence: I'm as sure as I can be.
Notes: Dark pronotum, brown elytra. There's a hint of a dark central/sutural patch on the elytra but not enough to be definitely A. vittatus, and this does occur in A. haemorrhoidalis, plus the patterns/colours overlap for these species. They can be separated by features on antennae, punctures etc, but the focus isn't good enough here. A. haemorrhoidalis is generally larger.
