Chrysis interjecta Buysson 1895: 541. Syntypes ♂♂, ♀♀; France: Provence (MNHN) (examined) (Chrysis aestiva group). Chrysis rosina Balthasar 1949: 2. Syntypes ♂, ♀; Czechoslovakia (JNMP).
Remarks. Tumšs & Maršakovs (1970: 94) reported a single female specimen from Latvia (Riga 2.6.1968) as Chrysis rosina. Subsequently also Soon (2004: 46) and Rosa & Soon (2012, as Chrysis interjecta interjecta) reported the species from Latvia, based on Tumšs’ & Maršakovs’ record. The Latvian specimen has not been found from the collection of the Natural History Museum of Riga. As C. interjecta is generally a southern European species, the existence of a distant isolated population in northern Europe is unlikely, and the record from Latvia is doubtful.
