The records from Siberia (Abakan river) are based on old mislabelled specimen of Jakovlev. The record from the Czech Republic in Putshkov & Moulet (2010) was based on Stehlík (1958) [not Hoberlandt, 1958!]) and refers to Slovakia. The record from the Czech Republic (Kment & Dolejšová, 2010) is considered an accidental introduction.
