Europe (ranging northward to the UK, Belgiumand Denmark). Ukraine, North Africa, Asia Minor.   Note.  Aedes rusticusis known within NWR according to several publications, i.e. from St Petersburg ( Fig. 3f; one locality; Fedorov, 1969), the Vologda Province (two localities; Sharkov, 1982) and the Kaliningrad Province (one locality; Bernotiene, 2012); it has been also recorded from Sweden, Latviaand Lithuania. On the other hand, we cannot confirm the occurrence of Ae.  rusticusin European Russiaby the material examined, i.e. the species is absent in our collections from the Leningrad Provinceand absent in the material of ZIN collection from NWR. Khalin & Gornostaeva (2008)did not list Ae.  rusticusfrom European Russia. The species is rare in the most part of its range ( Gutsevich et al., 1970). We consider that the correct northernmost record of Ae.  rusticusis that in the Kaliningrad Province. 4145056418 SPb 59.939095 1 30.315866 11 57 1 4145056341 VP 59.006485 Cherepovets Distr. 1 37.960308 11 57 1 4145056404 KP 55.155388 Zelenogradsk Distr. 1 20.850292 Rybachiy 11 57 1
