Labyrinthus leucodon is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Labyrinthidae.
The periphery of the shell of this species is acutely angulated. The spire is normally elevated, and the sides of the spire are flat to slightly rounded. The shell aperture is moderately deflected. Within the aperture, the high, simple parietal lamella starts descending before it runs into the parietal lip. The basal lip has a broad, prominent knob. The lower palatal tooth is a prominent, crescentic lamella, with strong lateral buttresses. The upper palatal lip often has a small tuberculate denticle.
The periostracum is brownish in color, occasionally speckled with greenish yellow.
