Tomocyclus is a genus of land snails, terrestrial gastropod mollusks in the subfamily Megalomastomatinae of the family Megalomastomatidae.[1]
Description
(Original description in Latin) The shell is perforated, turreted, and truncated. The aperture is subcircular and small. The peristome is double-layered: the inner layer is briefly projected inward, while the outer layer is broadly expanded, resembling a leaf. The upper margin of the outer lip is interrupted, with a unique, incised, and hollowed-out appearance.
The operculum is circular, corneous but relatively thick, and spirally wound. It is slightly flattened anteriorly and reinforced posteriorly by a blunt, rounded process. The margins of the operculum exhibit a somewhat lamellar structure. [2]
