    The shell of this exceeding small (2–4 mm) Valvata species is very flat in its coiling, and therefore it somewhat resembles a Planorbis shell. However, the shell is dextral in coiling and has an operculum. The shell is transparent, has 3-3.5 whorls in a circular aperture. The umbilicus is wide and open, more than 1/3 of shell diameter.

    Ecology

    This species lives in stagnant and slow-moving water.
