Abstract
Culex torrentium and C. vagans are morphologically similar mosquito species for which the name C. exilis has been used in Russia for a long time. We have compared the male genitalia in these species and analyzed the genetic differences between them, using specimens from different parts of their ranges. The results show that C. vagans can be readily distinguished from C. torrentium by the shape of the lateral arms of the phallosome. The genetic differences between the species are 3.5–3.6% for the COI gene and 14% for the ITS2 nuclear marker and reliably differentiated the two species. The ITS2 sequence of C. vagans is determined for the first time. The data obtained can be used to identify C. vagans and C. torrentium and to specify their ranges.

Notes
The balsam slides of Culex torrentium from Orenburg, Tomsk, Yessentuki, Kislovodsk, and Leningrad Province (nos. 277, 1169, 1400) were labeled as Culex exilis or Culex exilis = C. torrentium.
