This species was described in the year 1976 on the basis of two specimens, which had been found in the year 1934 on the small coral islet Tauna in the Gambier Archipelago, sitting on dead leaves.  

The shells reach an average size of 0,22 cm in diameter.

The Tauna Disc Snail was for a long time known only from the typus material, but then, in the year 1997, shells of this species were also found on the islands of Akamaru and Kouaku.
