Remarks. Omalium rivulare is a widely distributed species in the Holarctic region ( Schülke & Smetana 2015). It was recorded from Sverdlovsk Area (Belskaya & Kolesnikova 2011; Ermakov et al. 2017), and Tyumen Area ( Bukhkalo et al. 2012). It also was recorded from Krasnoyarsk Territory ( Shavrin 2010), but was misidentified and belongs to O. caesum . Records of the species from Yakutia ( Averenskiy 1999, 2003) and Maritime Province ( Kryzhanovskiy et al. 1973) require confirmation. It is also known from the northern regions of Russia west of Ural Mts. (e.g. Kolesnikova 2000).

It is here recorded from Khanty-Mansi Autonomous region , Tomsk and Novosibirsk areas from the first time.
