Rutilus pigus has been termed the Danube roach. The Danube drainage is not inhabited by R. pigus in the strict sense above, however. That region is inhabited by the closely related Rutilus virgo ("cactus roach"), which until recently was considered to be the same species as R. pigus, or its subspecies R.np. virgo. R. virgo is widespread from the Iron Gate upstream.[4]
