- Subspecies
- Amastra mucronata atroflava Hyatt & Pilsbry, 1911
- Amastra mucronata citrea Sykes, 1896
- Amastra mucronata mucronata (Newcomb, 1853)
- Amastra mucronata semicarnea Ancey & Sykes, 1899
- Amastra mucronata roseotincta Sykes, 1896 (taxon inquirendum)
Description
The length of the shell attains 17.5 mm, its diameter 8 mm.
The shell is dextral, elongate-ovate, and predominantly white, adorned with numerous transverse arrow-headed brown markings. The body whorl, however, is cloaked in a dense, brownish-black epidermis. It is composed of six rounded whorls, with the last one slightly contracted.
The suture is subtly impressed on the upper whorls, becoming more pronounced at the junction with the body whorl. The aperture is small and ovate, while the columella features a distinct twisted plait. The outer lip is simple and unembellished.
Distribution
This species is endemic to Hawai, occurring on Molokai island.
