Diplommatinidae

Diplommatinidae is a family of small land snails, also known as staircase snails, with an operculum, terrestrial gastropod mollusks in the superfamily Cyclophoroidea. The Cochlostomatinae Kobelt, 1902, were previously considered a subfamily of the Diplommatinidae, but are now known to be a separate family.
