Anatomy
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 when they are unable to reach the surface for air.

- Hebetancylus excentricus (Morelet, 1851)
- Hebetancylus moricandi (d’Orbigny, 1837)
