Described from Lenkoran, Azerbaijan ( Puthz 1971 : 100), Stenus claritarsis is distributed from eastern Europe (Austria, northern Balkans, Ukraine, South Russia) across Caucasia and Iran eastwards to Central Asia. In Iran, the species is widespread in the South Caspian mountains, where we collected it as far east as 51°29'E in western Mazandaran and in the Zagros Mountains southwards to 28°45'N in southeastern Fars. It was also found in the plain of Khuzestan (Fig. 21 ). Biogeographical characterization. Puthz (2012a : 312) proposed a Ponto-Mediterranean distribution for Stenus claritarsis , which is unlikely in view of the lack of records in all of the eastern Mediterranean. The distribution across Transcausasia and the South Caspian mountains points to an expansive Caspian faunal element.
