discussion
Remarks. The species has been recorded from all the Nordic and Baltic countries. It is not as common as H. ardens, but has a similar wide distribution. The northernmost records are from close to the Arctic circle in Finland. Dahlbom (1845: 3) described H. cupreum from female specimens collected in Sweden (“ H. cupreum nob. ♀ Svecia passim ”). As far as we know, only three specimens found in European museums have been determined as H. cupreum by Dahlbom as indicated by the original labels of the author. Two of these have been deposited in Spinola’s collection in Turin (MSNT), and the third one is preserved in Vienna (NMW). The specimen in Vienna is a female with the labels “ 41. “, “ H. cupreum Lund. Dhlb. “ (handwritten by Dahlbom?) and “ Dahlbom vidit 1850. “ (Fig. 3). Since this specimen was very likely collected in Lund by Dahlbom and later donated to the museum in Vienna, it probably belongs to the type series and therefore it is here designated as the lectotype, matching the current interpretation of the taxon. The specimen has two lectotype labels: one added by us here and an older one, added by P. Rosa in 2012. The older label is not valid, because a lectotype designation has not been published earlier. In Dahlbom’s collection in Lund (ZMUL) there is also one female specimen of H. cupreum, which has a lectotype label added by T. Peeters in 1996. This specimen, however, does not have type status either, because no lectotype designation has been published.
