Distribution. Denmark, Estonia, Finland, Latvia, Lithuania, Norway, Sweden, Russian Fennoscandia.—Transpalearctic: Europe, North Africa, Middle East, Mongolia, Russian Far East (Kimsey & Bohart 1991, Linsenmaier 1997, Kurzenko & Lelej 2007).
Remarks. The species is common in all Nordic and Baltic countries. In Norway, many specimens have been erroneously placed under the genus Holopyga in collections, and therefore the species has been wrongly considered as rare in the country. The northernmost records are from southern Finnish Lapland (Obb: Rovaniemi).
Dahlbom (1829) reported the species from Sweden initially with the name Chrysis integra. Although he attributed the authorship of the species to Fabricius, his description differs significantly from that of Fabricius (1793: 241), and they cannot be regarded as referring to the same species. Fabricius, for example, stated that the species resembles C. ignita in its shape (" Statura et summa affinitas C. ignitae "), whereas according to Dahlbom it resembles C. aurata (= Pseudomalus auratus) in its shape (" Statura Chr. aurata at paullo minor "). Apparently, Dahlbom had seen only Fabricius’ later shorter description of the species, published in 1804, which does not include information on e.g. the body shape. Later (1831), Dahlbom treated C. integra as three varieties (a, b and c), of which var. a referred to his original description of the species, and var. b and var. c represented new forms. Var. b can be seen as a green form of H. ardens, while var. c corresponds with the current interpretation of H. cupreum.
In 1845 Dahlbom transferred C. integra to the genus Hedychrum (as H. integrum) and described var. c as a new species, H. cupreum. Additionally, he reported H. ardens as a distinct species, closely related to H. integrum and rare in Europe. In 1854, Dahlbom found out that his earlier interpretation of integrum was a synonym of H. minutum Lepeletier de Saint Fargeau (= H. ardens), but erroneously proposed the name integrum as a replacement name for cupreum, considering cupreum to be a homonym of cupratum Klug. Dahlbom also wrongly considered ardens to be a synonym of lucidulum Fabricius (= Hedychrum nobile). As Dahlbom’s description of C. integra (= Hedychrum integrum of 1845) is valid (nec Fabricius, 1793) and corresponds with the current interpretation of H. ardens, the nominal species Chrysis integra Dahlbom, 1829 should be considered a new synonym of H. ardens.
