Chorology.

Stenus mongolicus is widely distributed in Asia and the Middle East from China, Mongolia, and East Siberia as far south as Indian Kashmir, Pakistan, Afghanistan, and Iran and westwards to Anatolia and Caucasia. In Iran, the species is restricted to the Elburz and Turkmeno-Khorasanian Mountains in the northeast and recorded as far south as 35°42'N in Razavi Khorasan (Fig. 3 ). Recent records from the lowlands of Ivanaky, Semnan Province ( Hadian et al. 2011: 4), and from rice fields and grassland in Lahijan, Gilan ( Ghahari et al. 2009c: 661) need confirmation.

Biogeographical characterization.

Kastcheev and Puthz (2011: 454) consider Stenus mongolicus as a Kazakhstan-Turanian species. Judging from its Central Asian distribution centre, Stenus mongolicus can be regarded as a Turkestanian faunal element, which expanded westward.
