Rhysodes sulcatus Fabricius, 1787

Distribution in Iran. Guilan ( Bodemeyer 1927).

General distribution. Bosnia Herzegovina, France, Germany, Hungary, Italy, Poland, Romania, Russia (South European Territory, West Siberia) , Sweden, Turkey, UK ( Bell 2003).

Comments. Bodemeyer (1927) reports this species as Rhysodes sp. from a river valley in the Elbruz Mountains. Only two species of this genus are distributed in Palaearctic region ( R. comes Lewis, 1888 which is restricted to Finland and Japan, and another R. sulcatus ). Regarding to their distribution we assumed strongly that the species collected from Guilan is the latter one.
