Aedes (Aedes) rossicus Dolbeskin, Gorickaja et Mitrofanova, 1930 *

Northernmost records (Fig. 2c). 58°31 ′ 37 ″ N, 31°15 ′ 2.36 ″ E, NP, Velikiy Novgorod * (Kunkova & Fedorova, 2003); 61°49 ′ 29.68 ″ N, 56°49 ′ 15.96 ″ E, Komi, Troitsko-Pechorsk Distr., Yaksha * (Panyukova & Ostroushko, 2017) .

Distribution. NWR: Komi*, NP*. Adjacent countries: Norway, Sweden, Finland, Belarus. Europe (ranging northward to France, Germany and Poland), European Russia (Chuvash Republic, Perm Territory, Orenburg Province, North Caucasus), South Siberia.

Note. Aedes rossicus has been recorded within NWR from the Komi Republic (two localities; Panyukova & Ostroushko, 2017) and the Novgorod Province (two localities; Kunkova & Fedorova, 2003). The West-European part of the distribution range of Ae. rossicus is still insufficiently known (Becker et al., 2010). This species is difficult for identification and can be reliably determined only by the male genitalia. Adult females of Ae. rossicus are externally similar to Ae. cinereus, differing from the latter in the lighter coloration of scales on the scutum and abdomen. We did not collect Ae. rossicus in NWR; the specimens of Ae. rossicus from NWR are absent from the ZIN collection. Probably, the records of Ae. rossicus from the Komi Republic and the Novgorod Province result from misidentifications.
