23. Hedychrum chalybaeum Dahlbom, 1854

Hedychrum chalybaeum Dahlbom 1854: 64 . Syntypes; Europe (ZMUL) (examined). Wengris 1962: 9, Tumšs 1976: 22 (as H. chalibaeum ), Soon 2004: 45, Orlovskytė et al. 2010: 146, Rosa & Soon 2012.

Distribution. Latvia, Lithuania.—Transpalearctic: from West Europe to Siberia, Mongolia and China ( Linsenmaier 1959).

Remarks. The species is very rare in the region. In Latvia it has been recorded in one locality (Krāslava) ( Tumšs 1976) and in Lithuania in three localities (Baltupiai, Karoliniškės, Leoniškės) ( Wengris 1962). We have checked the Latvian specimens, which are deposited in LMSZ in Riga. According to Orlovskytė et al. (2010), the Lithuanian specimens have not been found in collections. Buysson (1898: 548) reported “ H. lucidum var. Szaboi ” from St. Petersburg. Whether this record refers to H. chalybaeum is uncertain. The closest confirmed records outside Latvia and Lithuania are from the Pskov Oblast in Russia (23 km S of Sebezh, Krasikovo), Poland ( Banaszak 1980, Szczepko & Wiśniowski 2009), Belarus ( Shljachtenok 2006) and northern Germany ( Jakobs & Kornmilch 2007).
