Chorology.

Unlike other members of the Stenus fornicatus species group which are endemic to the eastern parts of the Palaearctic, Stenus fornicatus is widely distributed in the West Palaearctic including the Mediterranean and reaches East Siberia. In Iran, the species is hitherto known from the Hyrcanian zone of the northern slopes of the South Caspian mountain ranges only (Fig. 11 ).

Biogeographical characterization.

Due to the wide distribution of this species in the Mediterranean, Puthz (2012a: 288) considered Stenus fornicatus to be a Holomediterranean species. Here we follow this interpretation.
