Hedychrum rutilans rutilans: Rosa & Soon 2012 .

Distribution. Denmark, Estonia, Finland, Latvia, Lithuania.—Transpalearctic: Europe, North Africa, Turkey, Southwest Russia, Siberia ( Linsenmaier 1959, 1997, Kimsey & Bohart 1991).

Remarks. The species was reported from Sweden and Finland by Trautmann (1927: 74), Benno (1950: 33) and Haupt (1957: 54, as H. intermedium ). Additionally, Balthasar (1954: 126) reported the species from Finland and Trautmann (1930: 496) from Scandinavia. All these records are doubtful as we have not seen any Scandinavian specimens or Finnish specimens collected before the late 1950s in collections. As far as we know, the first record of H. rutilans in Finland was made in 1959 near the southeastern border, after which the species has been expanding its distribution towards the west, following its host Philanthus triangulum .
