discussion
Remarks. Hedychridium caputaureum has often been confused with H. roseum in the Nordic and Baltic countries and its distribution is still not well known. It has possibly been overlooked in Denmark and Norway. Compared to H. roseum, it is less common and strictly confined to areas with populations of its crabronid host Astata minor. It has been classified as vulnerable in Finland (Paukkunen 2010) and Sweden (Cederberg et al. 2010). Arens (2010) considered caputaureum to be a subspecies of H. chloropygum, while Linsenmaier (1959) had earlier classified it as a subspecies of H. roseum. According to Arens, H. chloropygum consists of two subspecies in Europe: ssp. chloropygum (distributed from the Iberian peninsula to Hungary) and ssp. caputaureum (from central, southeastern and northern Europe). A third subspecies, ssp. ottomanum, is found in Asia Minor. The taxa spatium and densum of Linsenmaier (1959) were synonymized with ssp. caputaureum by Arens. We consider chloropygum and caputaureum to be separate species, as they are both well characterized and have partially overlapping distribution areas. Also e. g. Niehuis (2001) and Rosa (2006) treated H. caputaureum as a distinct species.
