Swedish sources: Mycetophila thoracica: Zetterstedt 1838:864 [LY]; Zetterstedt 1852:4177 [ÖG, UP, Swedish Lapland]; Dynatosoma thoracicum: Wahlgren 1921:192 [ÖG]; Wahlgren 1921:192 [Swedish Lapland]; Hackman et al. 1988:264 [LY]; Kallweit 1990:163 [LY], Chandler (2005) [Sweden]. Dynatosoma norwegiense: Kurina et al. 2005:480 [SM, ÖG, VG]; Dynatosoma thoracicum: Kjærandsen et al. 2007:78 [Boreal–boreonemoral — •SM•ÖG•VG•SÖ•UP•VB•LY•]; Jakovlev, Kjærandsen & Viklund 2008:39 [SÖ].
World distribution: Palaearctic; widely distributed in Europe.
Remarks: Kallweit (1990) synonymized this species with D. rufithorax Strobl, 1895 after examination of both holotypes. Our re-examination of the holotype of D. thoracicum clearly shows that D. norwegiense is a junior synonym, and that D. thoracicum sensu Zaitzev (1986, 2003) belongs to another, most likely undescribed species that will be presented elsewhere.
