The beetle is reddish brown with antennae that gradually thicken into an indistinct club shape with four club segments (the Red Rust Flour Beetle has a prominent three segment club on the end of the antennae). There is a distinct ridge above each eye. The sides of the thorax of the Red Flour Beetle are curved whereas those of the Confused Flour Beetle are more parallel. somewhat straighter. The Confused Flour Beetle does not usually fly.
