Material examined. *Russian Fennoscandia: Ik: Metsäpirtti [= Zaporozhskoe], 26.VI.1920, 1 ♂ (W. Hellén); Ka: Penisaari [= Ostrov Malyy], 11.–14.VII.1932, 2 ♂♂ (W. Hellén).

Distribution. Finland, *Russian Fennoscandia.—Westpalearctic: not known outside eastern Fennoscandia.

Remarks. The species is very rare and only known from three coastal localities in Finland (N: Hanko, Om: Kokkola, Oba: Oulu) and two localities in Russian Fennoscandia. In Finland, it is classified as critically endangered ( Paukkunen 2010). The species was erroneously synonymized with H. fervida by Trautmann (1927) and Linsenmaier (1951, 1959). However, Linsenmaier (1987) later reinstated it as a valid species.

Dahlbom (1854) described the species as Hedychrum metallicum on the basis of one specimen collected by W. Nylander from Finland in 27.VII.1844. The holotype is a small male, and it is deposited in MZH in Helsinki ( Fig. 2 ). It has the original labels “Uleåborg” (= Oulu), “d. 27/7 44”, “ Coll. Nylander ”, “n. sp.?” and “256.”. Type labels have been added later, including the holotype label.
