Boettgeria
Boettgeria is a genus of small, very elongate, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Clausiliidae, the door snails, all of which have a clausilium.
This genus of door snails should not be confused with a genus of slugs that has a similar name: Boettgerilla Simroth, 1910.
