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

Distribution

The distribution of genus Coxiella includes Tasmania[3] and Australia: southern Australia, central Australia and northern Queensland.[4]

Species

Davis (1979)[3] recognized 10 species (9 in Australia) and one subrecent species Coxiella badgerensis in Tasmania.[3]

Species within the genus Coxiella include:

subgenus Coxiella

  • † Coxiella badgerensis (Johnston, 1879) - subrecent[3]
  • Coxiella exposita Iredale, 1943[3]
  • Coxiella glabra MacPherson, 1957[3]
  • Coxiella glauertii MacPherson, 1954[3]
  • Coxiella minima MacPherson, 1954[3]
  • Coxiella molesta Iredale, 1943[3]
  • Coxiella pyrrhostoma (Cox, 1868)[3]
  • Coxiella striata (Reeve, 1842)[3]
  • Coxiella striatula (Menke, 1843) - type species[3]

subgenus Coxielladda Iredale & Whitley, 1938[5]

  • Coxiella gilesi (Angas, 1877)[3]

Ecology

This genus consists of halophilic species which occur in temporal and permanent saline lakes.[4][6]

Coxiella snails are iteroparous.[4] When the saline lake dries out, adults of Coxiella are able to survive.[4]
