Chorology.

The nominotypical subspecies of Stenus providus is widespread in the West Palaearctic as far east as Kazakhstan ( Kastcheev and Puthz 2011: 450). The first record for Iran in this work is missing in the current Catalogue of Palaearctic Coleoptera ( Schülke and Smetana 2015: 837). In Iran, Stenus providus providus is distributed in the South Caspian mountains and the very north of the Zagros Mountains (Fig. 8 ). In the Hyrcanian zone, the species is replaced by its close, allopatric relative Stenus caspius , but in high elevations of the northern slopes of the Elburz Mountains there is a narrow zone of sympatry.

Biogeographical characterization.

Judging from the distribution in all of the arboreal Mediterranean, Stenus providus is to be attributed to the Holomediterranean distribution type. Kastcheev and Puthz (2011: 454) already described it as a Mediterranean species.
