Chorology.

Stenus morio is a Holarctic species with a trans-Palaearctic distribution. The first records for Iran (West and East Azarbaijan) were published only recently by Ghahari et al. (2009b: 1964). However, we were not given the opportunity to see the underlying specimens. Like other members of the Stenus melanarius group, Stenus morio seems to be rare in Iran and restricted to the northwest of the country, because we collected it in the northern Zagros (Hamedan Province) only (Fig. 17 ).

Biogeographical characterization.

The trans-Palaearctic distribution of Stenus morio can not be explained by particular Pleistocene refuges.
