Most similar to A. strigatus and A. spretulus, but the lack of posterior femoral lines and significantly shallower punctures of the pronotum will quickly distinguish this species. (Stebnicka & Lago 2005)
Biological notes recorded for A. cognatus by Hoffman (1935) almost certainly refer to A. strigatus or A. spretulus.
