Amastra rubristoma is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Amastridae.
Description
The length of the shell attains 19.12 mm, its diameter 12 mm
The shell is dextral, imperforate, solid, and elongately ovate-conic, with an acute apex. The surface is marked by irregular growth striae, and the nuclear whorls are delicately radiately sulcated. Its coloration varies from reddish-brown to almost white, with darker upper whorls, often covered by a dark, fugacious epidermis. There are seven convex whorls with a well-impressed suture.
The aperture is slightly oblique and oval, with a red interior that occasionally appears livid-white. The peristome is acute and subtly thickened within. The columella ends in a strong, arched, lamellar plait, faintly tinged with red.
Distribution
This species is endemic to Hawaii, occurring on the main island at Hilo.
