Zospeum bucculentum is a cave-dwelling species of air-breathing land snails (Eupulmonata, Ellobioidea, Carychiinae).

The species was established based on specimens that previously were classified as Z. isselianum or Z. likanum.

It is smooth, transparent and has a conic shape with approximately 5 slightly shouldered whorls, sometimes with an obtuse keel.

The peristome is roundish to oval, with a straight or rounded parietal shield, which is well-differentiated from the lip.

Additionally, specimens were discovered in Zvonečka II and Jama Đot, which are considered to belong to Zospeum bucculentum based on shell morphology.
