Kaliningrad Region: Gur. (Juditten, Königsberg, Metgethen, Wilkie), Zel. (Georgenshöhe, Rauschen, Warnicken).

Comments: Formerly widespread at least in western parts of the Region. Widespread in the Baltic States and Fennoscandia (Silfverberg 2010), known in Lithuania (Bercio & Folwaczny 1979; Tamutis et al. 2011), Belarus (Alexandovitch & Pisanenko 1991) and north-western Poland (Byk 2012). The presence of the species in the regional fauna needs actual confirmation.
