Chorology.

Stenus callidus exists in the Balkans, Caucasia, and the Middle East. According to Puthz (2008: 157), the record for Kyrgyzstan in Smetana (2004: 555), which was adopted by Schülke and Smetana (2015: 810), is based on a misidentification and probably refers to Stenus cephallenicus . Stenus callidus is the second widespread species of the genus (Fig. 15 ) in Iran. It was recorded in all of the northwest, in the northern Qohrud Range, and in the Elburz as far east as 53°38'E in eastern Mazandaran. Most frequently, however, it was collected in the Zagros Mountains. The records from southeastern Iran at about 56°E in the provinces of Hormozgan and Kerman considerably extend the range of this species towards east.

Biogeographical characterization.

Due to its vast distribution in the eastern Mediterranean, Anatolia ( Puthz 2008: 153), and Iran, Stenus callidus can be considered as an expansive Pontomediterranean species.
