Material examined. Table 1; Fig. 5.

Presence of 56–71 lateral plates and first dorsal plate not fused to the head. It was not collected in this study, but was observed in the middle and upper reaches of the Moksha River on a regular basis ( Kuznetsov et al. 2008, Lysenkov and Pjanov 2015) ( Fig. 5). Over the last decade, the abundance of this species has increased in

the Moksha River, likely due to a regular release of the juveniles into the Oka River ( Lysenkov et al. 2006).
