Alopia glauca is a species of small, tropical, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Clausiliidae.

(original description in German) Animal: the upper surface is black-gray, densely covered with elongated granules that converge into five longitudinal lines along the neck; the sole is blue-gray.

It is spindle-shaped and slightly swollen, featuring raised, irregular ribs that evolve into densely spaced, regular longitudinal striae.

The surface is matte-glossy, violet in color, with a reddish apex, and when fresh, covered with a bluish bloom.

The suture line and the densely wrinkled, prominently swollen neck are white.
