Tomichia differens is a species of freshwater gastropod in the family Pomatiopsidae endemic to perennial streams and rivers in Western Cape Province, South Africa. T. differens was described by Connolly in 1939. It is found in two sites at De Kelders and Stilbaai, and has amphibious habits and a tolerance of slight salinity and desiccation throughout its habitats. The genus Tomichia is very sensitive to changes in ecosystem conditions, and thus are threatened by pollution and climate change. The Stilbaai site is in danger of becoming uninhabitable due to residential developments and offshore drilling operations, and thus this species has been listed as Endangered by the IUCN.
Gittenedouardia is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Cerastidae.
