Аннотация

The American rotifer Kellicottia bostoniensis (Rousselet, 1908) was first recorded in the Kama Reservoir (Kama River, Middle Volga basin) in 2012. The species was found in over 70% of the samples; its maximum abundance was 2000 ind./m³. This alien species co-existed with closely related native species K. longispina (Kellicott). This is the easternmost location (56°–57° E) for K. bostoniensis in the Volga River basin and in Europe.
