I think this is a mix of A. brunnipennis and A. hirsutus (= now A. explanatus). In the first image, the top two are A. hirsutus and the bottom one is A. brunnipennis. Second image is A. brunnipennis; third and fourth A. hirsutus. A brunnipennis does not have the white setae on the pronotum and face. I've seen both species together twice myself now in aggregations.
