Ancylini is a tribe of small, freshwater, air-breathing limpets, aquatic pulmonate gastropod mollusks in the family Planorbidae, the ram's horn snails and their allies. This tribe used to be treated as a family; the current taxonomic placement within Planorbidae is according to the taxonomy of the Gastropoda (Bouchet & Rocroi, 2005).



These animals have a pallial lung, as do all pulmonate snails, but they also have a false gill or "pseudobranch" which can serve perfectly well as a gill in situations where the limpet is unable to reach the surface for air, as is often the case.

  • Ancylus Müller, 1773 - type genus
  • Pseudancylus
  • Rhodocephala
  • Ferrissia Walker, 1903
  • Rhodacmea Walker, 1917
