Chorology.

The Middle Eastern Stenus asiaticus is recorded for Georgia, Turkey, Syria, Iraq, Iran, and Turkmenistan. In Iran, it is the most widespread member of the Stenus comma species group and distributed in the South Caspian mountains and the northern Zagros Mountains (Fig. 9 ).

Biogeographical characterization.

It is difficult, to assign Stenus asiaticus to a particular distribution type judging from the total distribution. In view of the high abundance of records in the Hyrcanian zone in the northern slopes of the Elburz Mountains and the distribution in Transcaucasia, the regions which constitute the Caspian refuge, we consider Stenus asiaticus to be an expansive Caspian faunal element.
