Chorology.

Stenus biguttatus is widely distributed across the northern Palaearctic eastwards to Russian Far East and Japan ( Kastcheev and Puthz 2011: 440). In Iran, the species seems to be rare and restricted to the northwest, where we collected it just once (Fig. 9 ). The dubious records from Rasht and Fouman published by Samin et al. (2011a: 2, 2011c: 1238) were not adopted by Schülke and Smetana (2015: 808).

Biogeographical characterization.

The enormous area of distribution of Stenus biguttatus cannot be attributed to a particular Pleistocene refuge and distribution type, respectively.
