Thesbia

Thesbia is a genus of sea snails, marine gastropod mollusks in the family Cancellariidae, the nutmeg snails.

Description:

Thesbia species are characterized by their cancellate sculpture, consisting of spiral ridges and axial ribs that intersect to create a net-like pattern on the shell's surface. Shells are typically small to medium in size. The aperture is usually ovate or elongate, and the outer lip may be lirate (having ridge-like markings) internally. The columella (the central pillar of the shell) has plications (folds or ridges), a characteristic feature of the Cancellariidae family.

Distribution:

Species within the Thesbia genus are found in various regions of the world's oceans.

Several species have been assigned to the genus Thesbia. Specific species assignments may change as taxonomic classifications are refined based on ongoing research. Some species previously listed in this genus have been reclassified.
