Cepaea is a genus of medium-sized air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Helicidae. The shells of species within this genus are often brightly colored and patterned with stripes.[2] The two species from this genus, the common and widespread C. nemoralis and C. hortensis, have been model species for early studies of genetics and natural selection.[3] They occur in Europe, although introduced populations occur elsewhere in the world.[4]

Like many Helicidae, this genus of snails create and use love darts.[2]

Species[]

For a long time, four species were classified in the genus Cepaea.

However, molecular phylogenetic studies suggested that the latter two should be placed in the unrelated genera Macularia and Caucasotachea:[5][6]

  • Cepaea hortensis (O. F. Müller, 1774) – white-lipped snail or garden banded snail
  • Cepaea nemoralis (Linnaeus, 1758) – brown-lipped snail or grove snail
  • Cepaea sylvatica (Draparnaud, 1801), now Macularia sylvatica
  • Cepaea vindobonensis (Férussac, 1821), now Caucasotachea vindobonensis
