Live footage

The adult beetle is a small, 2-3mm, very flattened and brown with the pronotum having characteristic "sawtoothed" outer margins, bearing six "teeth" on each side.


A closely related species, the merchant grain beetle, Oryzaephilus mercator (Fauvel), is very similar but its head capsule measurements differ as follows: the temple region just behind the eyes is shorter, less than the vertical diameter of the eye for the merchant grain beetle, being longer for the sawtoothed grain beetle.
