Diversity[2]
10 species

Coxiella is a genus of aquatic gastropod mollusks in the family Tomichiidae. These snails that live in saline lakes, and have gills and an operculum.

Distribution

The distribution of genus Coxiella includes Tasmania[2] and Australia: southern Australia, central Australia and northern Queensland.[3]

Species

Davis (1979)[2] recognized 10 species (9 in Australia) and one subrecent species Coxiella badgerensis in Tasmania.[2]

Species within the genus Coxiella include:

subgenus Coxiella

  • Coxiella badgerensis (Johnston, 1879) - subrecent[2]
  • Coxiella exposita Iredale, 1943[2]
  • Coxiella glabra MacPherson, 1957[2]
  • Coxiella glauertii MacPherson, 1954[2]
  • Coxiella minima MacPherson, 1954[2]
  • Coxiella molesta Iredale, 1943[2]
  • Coxiella pyrrhostoma (Cox, 1868)[2]
  • Coxiella striata (Reeve, 1842)[2]
  • Coxiella striatula (Menke, 1843) - type species[2]

subgenus Coxielladda Iredale & Whitley, 1938[4]

  • Coxiella gilesi (Angas, 1877)[2]

Ecology

This genus consists of halophilic species which occur in temporal and permanent saline lakes.[3][5]

Coxiella snails are iteroparous.[3] When the saline lake dries out, adults of Coxiella are able to survive.[3]
