This species was described in 2014 based on subfossil shells that had been obtained from deposits inside the Moumu Cave on the island of Makatea in the Tuamotu Archipelago.
The shells are less than 0,4 cm in diameter; they are depressed, white and don’t bear any flammulations.

This species from the island of Maupiti was described in the year 1884.
The shells reach an average size of 0,3 cm in diameter; they are light yellowish horn-colored with vague, somewhat regularly spaced, reddish flammulations. [2]
***
Andrew J. Garrett, the species’ author, writes in the year 1884.:
“Very common, and confined to the small island of Maupiti.” [1]
Thus, the Maupiti Disc Snail, of which today 21 museum specimens are still in existence, must still have been very common in the 19th century, but died out shortly after.

The Huahine Mautodontha Snail was described in 1884; it was restricted to the island of Huahine, Society Islands.
The shells reach an average size of 0,38 cm in diameter, the largest are up to 0,43 cm in diameter; they are light yellowish horn-colored with broad, frequently spaced zigzag-shaped, reddish flammulations. [2]
Andrew J. Garrett, the species’ author writes in the year 1884.:
“Rare and peculiar to one valley.” [1]
This statement is all, that is known about this now extinct species, of which obviously only seven museum specimens are in existence.
