Dianous coerulescens , widely distributed in the temperate West Palaearctic, is recorded as far east as Kazakhstan ( Kastcheev and Puthz 2011 : 438) and western Siberia ( Schuelke and Smetana 2015 : 799). Judging from the distribution in the Caucasus and Turkey ( Schuelke and Smetana 2015 : 799), the occurrence in northern Iran was expected. One male of Dianous coerulescens , which was collected in moss at a small waterfall in the northern slope of Mount Sabalan, represents the first record of both the genus and the species in Iran (Fig. 2 ). This southernmost finding of the polytypical species at 38°19'N belongs to Dianous coerulescens korgei Puthz, 2002, which was hitherto known only from the type locality near Trabzon, Northeast Turkey. Biogeographical characterization. Dianous coerulescens cannot be assigned to any of de Lattin's (1951 , 1957 , 1967 ) southern Palaearctic glacial refuges.
