Chorology.

The Holarctic Stenus comma is widespread across the temperate and northern Palaearctic as far east as Russian Far East, China, and Japan. In Iran, the northern species seems to be confined to the temperate northwest. Our find in West Azarbaijan constitutes the first country record of Stenus comma comma for Iran (Fig. 9 ).

Biogeographical characterization.

The wide distribution of this species cannot be explained by the Pleistocene refuge theory.
