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

[citation needed] (Original description in Latin) The conical-globose shell is somewhat thin, smooth and shiny.

The columella is short, receding, slightly toothed at the base, and emits a circumscribed callus.

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.
