Pseudodiamesa nivosaa species commonly regarded as a boreo‐alpine one, has been recorded at an altitude of 345 m a.s.l., in the source section of the Pilica River (Cracow‐Czestochowa Upland, Poland) and in one of the vaucluse springs in the Roztocze Region (230 m a.s.l.). It seems that the newly recordedP. nivosapopulations might be regarded as a glacial relict connected with the periglacial zone.
