Ammonicera is a genus of minute sea snails, marine gastropod molluscs or micromollusks in the family Omalogyridae. [1]
Species within the genus Ammonicera include:
Rostanga is a genus of sea slugs in the family Discodorididae. Some sources, such as The Sea Slug Forum still classify Rostanga in the family Dorididae.
Omalogyridae are a family of minute and microscopic sea snails, marine gastropod molluscs or micromolluscs in the informal group Lower Heterobranchia. Adult shells are usually smaller than 1 millimeter.
Omalogyra is a genus of minute marine gastropod molluscs in the family Omalogyridae.
Lodderena is a genus of minute sea snails or micromolluscs, marine gastropod molluscs, formerly in the family Skeneidae. Following a morphological reevaluation, it was excluded from Skeneidae and treated as incertae sedis within the superfamily Trochoidea.
Bactrocythara agachada is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.
Crisilla is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Rissoidae.
Obtusella is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Rissoidae.
Zebina is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Zebinidae.
Adeuomphalus is a genus of sea snails, marine gastropod molluscs unassigned to family within the superfamily Seguenzioidea.
Berthellina is a genus of sea slugs, marine gastropod molluscs in the family Pleurobranchidae.
Melanochlamys is a genus of headshield slugs in the family Aglajidae. Despite the appearance of its species, this genus must not be confused with nudibranchs.
Retrotortina is a genus of very minute sea snails, marine gastropod molluscs or micromollusks in the family Omalogyridae.
Rüdiger Bieler is a German-American biologist whose primary scientific field of study is malacology, the study of mollusks.
After excluding groups not related, the informal group Sigmurethra has become the suborder Helicina, with the following infraorders and a collection of families with no superfamily:
Neopilina bruuni is a species of monoplacophoran, a superficially limpet-like marine mollusc. It is found in the southeastern Pacific Ocean, off the coast of South America.
Rokopella brummeri is a species of monoplacophoran, a superficially limpet-like marine mollusc. It is found in the northern Atlantic Ocean.
Rokopella oligotropha is a species of monoplacophoran, a superficially limpet-like marine mollusc. It is known from only one specimen and a shell fragment collected in the north-central Pacific Ocean.
Monoplacophorus zenkevitchi is a species of monoplacophoran, a superficially limpet-like marine mollusc. It is known from only one specimen collected from a depth of 2000 metres in the Pacific Ocean, north of Johnston Island and west of Hawaii.
Adenopilina adenensis is a species of monoplacophoran, a superficially limpet-like marine mollusc. It is known from only one specimen collected from a depth of 3000–4000 metres in the Alula-Fartak Trench of the Gulf of Aden, off the coast of Yemen.
Amonovula is a monotypic genus of marine gastropod molluscs in the family Ovulidae, the ovulids, cowry allies or false cowries
