Tropidoptera is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Amastridae. [2]
(Described as Endodonta (Pterodiscus)) The shell is umbilicated, depressed, thin, or fragile, with a translucent horny-brown coloration.
The whorls are finely and densely striated, with the body whorl sharply keeled at the periphery and distinctly carinated around the umbilicus. The aperture is oblique and toothless, with a thin, simple lip. [3]
It is endemic to the Hawaiian Islands.
