Alcadia spectabilis is a species of an operculate land snail, terrestrial gastropod mollusk in the family Helicinidae.

Description

The height of the shell attains 6 mm (0.24 in), its greatest diameter 8 mm (0.31 in).^{[citation needed]}

(Original description in Latin) The conical-globose shell is somewhat thin, smooth and shiny. It is yellow with a darker or blood-red peripheral band, or pink with a blood-red band. The spire is convex-conical with a sharp, dark blood-red apex. It has 5 slightly convex whorls, with the body whorl rounded and scarcely equal to the spire. The columella is short, receding, slightly toothed at the base, and emits a circumscribed callus. The aperture is oblique and broadly semi-oval. The peristome is thin and expanded, with the basal margin forming a slightly right angle with the columella. The operculum is transparent, purplish, and pale on the columellar side.

Distribution

This species lives in Cuba.
