A revolution in Sphaeriid Systematics? A critical note on the splitting tendency by the well-known Ukrainian pisidiologist A. Korniushin as worded in the Abstract (p. 418/9) of the Union Malacologica published after its 12th congress at Vigo (Spain), 1995. Question: are the soft parts or is the shell essential in sphaeriid identification? Shells without soft parts are identifiable, but identification of animals without shell is impossible at present.
