Tengchiena is a genus of very small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Microcystidae, the hive snails. [1]
Species within the genus Tengchiena include:
Ampullariidae, whose members are commonly known as apple snails, is a family of large freshwater snails that includes the mystery snail species. They are aquatic gastropod mollusks with a gill and an operculum. These snails simultaneously have a gill and a lung as functional respiratory structures, which are separated by a division of the mantle cavity. This adaptation allows these animals to be amphibious. Species in this family are considered gonochoristic, meaning that each individual organism is either male or female.
Helicinidae is a family of small tropical land snails which have an operculum. They are terrestrial operculate gastropod mollusks in the superfamily Helicinoidea.
Neritidae, common name the nerites, is a taxonomic family of small to medium-sized saltwater and freshwater snails which have a gill and a distinctive operculum. The family Neritidae includes marine genera such as Nerita, marine and freshwater genera such as Neritina, and freshwater and brackish water genera such as Theodoxus.
Discus is a genus of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Discidae, the disk snails.
Brazieria is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Trochomorphidae.
Ponapea ponapensis, formerly Dendrotrochus ponapensis, is a species of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Euconulidae, the hive snails. This species is endemic to Micronesia.
Dendrotrochus is a genus of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Trochomorphidae, the hive snails.
Kondoa is a genus of mostly small, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Trochomorphidae.
Tengchiena euroxestus is a species of very small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Microcystidae, the hive snails.
Subulininae is a subfamily of small tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Achatinidae.
Trochomorphidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Gastrodontoidea. Since 2017, its classification has been revised and it now belongs to the superfamily Trochomorphoidea
Diastole is a genus of air-breathing land snails or semi-slugs, terrestrial pulmonate gastropod mollusks in the family Microcystidae.
Rectaxis is a genus of predatory air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Spiraxidae.
Maurea is a genus of sea snails, marine gastropod mollusks, in the family Calliostomatidae within the superfamily Trochoidea, the top snails, turban snails and their allies.
Puha is an extinct genus of sea snails, marine gastropod mollusks in the family Raphitomidae.
Entomostoma is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Trochomorphidae.
Probrazieria is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Trochomorphidae.
Cylichnella is a genus of sea snails or bubble snails, marine gastropod molluscs in the family Cylichnidae, the "chalice bubble snails".
Microcystidae is a family of land snails in the order Stylommatophora.
