Chorology.

The Holarctic Stenus canaliculatus is widely distributed across the temperate and northern Palaearctic as far east as Russian Far East and China. In Iran, the species is confined to the temperate north (West Azarbaijan, Ardabil, Mazandaran; Fig. 5 ). Thus, the record from Fars ( Samin et al. 2011a: 2, 2011c: 1238), far south of the confirmed distribution, is implausible.

Biogeographical characterization.

Stenus canaliculatus , a faunal element of the temperate Holarctic, cannot be assigned to any of de Lattin’s (1951, 1957, 1967) southern Palaearctic glacial refuges.
