Ampelita xystera is a species of tropical air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Acavidae. ^[1]

Description

The height of the shell attains 16 mm, its diameter 45 mm.

(Original description in Latin) The shell is orbicular, depressed, and umbilicate, characterized by a very sharp keel. It is thin, translucent, and olive-brown in color. The suture is barely discernible. The shell exhibits four flat whorls that increase rapidly in size, with the body whorl being convex at the base. The umbilicus is wide, funnel-shaped, pervious, and margined. The aperture is very oblique, depressed, and irregular in shape. The peristome is reflexed and sinuate, and the columellar margin ascends in a nearly straight line. ^[2]
