Anale zachte stralen: 12 - 13. Can be distinguished from other species of Cottus in the Danube drainage by the combination of the following characters: dorsal head length 19-20% SL; 12-13 1/2 anal-fin rays; 18-19 1/2 rays in second dorsal fin; predorsal length 29-30% SL; distance from tip of snout to origin of second dorsal fin 47-50% SL; no distinct transverse bands on pelvic fin; no prickling on body (Ref. 55856).
Recorded from a cold and fast-flowing stream (Ref. 59043).
