Amastra tenuilabris is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Amastridae.[1]
Subspecies: Amastra tenuilabris rubicunda (Baldwin, 1895)
The length of the shell attains 15 mm, its diameter 8 mm
The shell is dextral, ovate-conic, and slightly dull, marked with somewhat coarse growth striations. It is white, overlain by a tawny epidermis that tends to wear away below the suture on the body whorl. There are 5½ whorls, which are gently convex. The aperture is subquadrate, white, and shorter than the spire. The peristome is thin, and the columella is straight, featuring a small central fold. The lips are joined by a delicate, thin callus.[2]
