Remarks. This species develops on Sphaerophysa salsula (Pall.) DC. ( Lukjanovich and Ter-Minassian 1957) . We collected it from this plant (fig. 3) growing on the shore of a salt lake.

Distribution. Asia minor ( Iran), Turkmenistan, Kyrgyzstan, Kazakhstan, Russia, China (Xinjiang), Mongolia (Bayankhongor and Ömnögovi prov.) (fig. 4). This species is listed in the general distribution for Russia, South Africa, Turkey ( Li et al. 2014), but we think that this is an erroneous records.
