Remarks.

Hedychrum callosum Radoszkovsky, 1877 was considered a synonym of Hedychridium aheneum (Dahlbom, 1854) by Mocsáry (1887: 13; 1889: 146), Dalla Torre (1892: 20), and Bischoff (1913: 14). Trautmann (1927: 56) considered Hedychridium aheneum as a variety of Hedychridium incrassatum (Dahlbom, 1854), and therefore placed Hedychrum callosum in the synonymic list of Hedychridium incrassatum . The following authors (e.g. Linsenmaier 1951: 98; Kimsey and Bohart 1991: 196) re-evaluated Hedychridium aheneum , but Hedychrum callosum remained in synonym with Hedychridium incrassatum . Hedychridium incrassatum is found only in the western Mediterranean countries, while Hedychridium aheneum is spread in the eastern Mediterranean countries, Middle East and central Asia ( Linsenmaier 1959, 1968). In southern Italy both Hedychridium aheneum and Hedychridium incrassatum (described from Sicily) are present ( Strumia 1995).

Current status.

Hedychridium aheneum (Dahlbom, 1854) (synonymised by Mocsáry 1887).
