Synonyms
  • Cerostoma Conrad, 1837 (invalid: junior homonym of Cerostoma Latreille, 1802 [Lepidoptera]; Ceratostoma is an emendation )
  • Microrhytis Emerson, 1959
  • Pteropurpura (Ceratostoma) Herrmannsen, 1846

This genus should not be confused with the nudibranch genus Ceratosoma, meaning "thorn body". Ceratostoma means "thorn mouth" because of the thorn-like projection on the edge of the aperture, used as a tool in predation to prop open the shells of bivalves and barnacles.
