Fluvidona orphana is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the family Tateidae.
The specific epithet orphana is derived from the Greek word orphanos, meaning orphan, and refers to the probable extinction of any related species in the surrounding areas because of land clearing for urban development. [1]
This species is endemic to northern New South Wales, Australia. It is known only from Sea Acres Reserve, Port Macquarie, where it lives in a small stream in a patch of remnant coastal rainforest. It differs from all other Fluvidona species in its habit, being found crawling on palm fronds, etc., in the creek and is also relatively abundant. [1]
Fluvidona anodonta or more commonly known as the North Pine River freshwater snail is a species of minute freshwater snail that is endemic to Australia. Originally discovered in 1892 by Hedley & Musson, the snail is highly elusive and only has been sighted four times since its discovery. The snail is 2 mm long and 1 mm wide with the shell colouring being of a yellow-whiteish shade. Fluvidona anodonta resides within the City of Moreton Bay, specifically in four river systems within the D'Aguilar National Park, Queensland. The four river systems are the South Pine River headwaters, the North Pine River headwaters, Kobble Creek and Low Branch Creek. The snail is found under deeply submerged rocks within permanent freshwater systems.
Fluvidona simsoniana is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the family Tateidae. This species is endemic to Australia.
Beddomeia waterhouseae, also known as Claytons Rivulet freshwater snail, is a species of freshwater snail in the family Tateidae. This species is endemic to northern Tasmania in Australia. The holotype specimen was found in a very small tributary of Little Clayton's Rivulet and is held at the Australian Museum. B. waterhouseae is small and as an adult has a shell measuring between 1.7 to 3.7 mm in length. The shell shape is ovate-conic to broadly conic and has a thin inner lip and no columellar bulge. This species feeds on algae and detritus on rocks. The female of the species lay single eggs in capsules made of sand grains and attached to the underside of rocks or wood. B. waterhouseae is considered vulnerable by the IUCN as it has a very small range and is sensitive to water quality and so may be threatened by disturbances of its habitat. Other threats include habitat loss. Conservation activities such as assessment of the aquatic ecosystem and vegetal surveys are being undertaken in an attempt to preserve this species.
Winston Frank Ponder is a malacologist born and educated in New Zealand who has named and described many marine and freshwater animals, especially micromolluscs.
Austropyrgus is a genus of minute freshwater snails with an operculum, aquatic gastropod molluscs or micromolluscs in the Hydrobiidae family. Austropyrgus species are endemic to Australia, where they are found in virtually all freshwater habitats, from high mountain streams to isolated springs in the arid zone.
Austropyrgus bungoniensis is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the Hydrobiidae family. This species is endemic to southern New South Wales, Australia. It is known from streams and springs flowing from the Bungonia Gorge Caves.
Austropyrgus bunyaensis is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the Hydrobiidae family. This species is endemic to southeastern Queensland, Australia. It is only known from small streams near the top of Mount Mowbullan, Bunya Mountains.
Austropyrgus centralia is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the Hydrobiidae family. This species is endemic to northern South Australia. It is only known from a few small seeps and the shallow lower outflow of one larger spring in Dalhousie Springs, Lake Eyre basin.
Austropyrgus nepeanensis is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the Hydrobiidae family. This species is endemic to New South Wales, Australia. It is known from a few small tributaries of the Nepean River in western and south western Sydney.
Austropyrgus ora is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the Hydrobiidae family. This species is endemic to eastern Victoria and southern New South Wales, Australia.
Austropyrgus rectoides is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the Hydrobiidae family. This species is endemic to Tasmania, Australia. It is found in small coastal rivers and streams in northern and western Tasmania and also on Hunter Island.
Austropyrgus ronkershawi is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the Hydrobiidae family. This species is endemic to Tasmania, Australia. It is known from a number of small streams and rivers in central northern Tasmania.
Fluvidona is a genus of minute freshwater snails with an operculum, aquatic gastropod molluscs or micromolluscs in the family Tateidae. Fluvidona species are endemic to northern New South Wales and southern Queensland, Australia.
Fluvidona dorrigoensis is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the family Tateidae.
Fluvidona griffithsi is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the family Tateidae. This species is endemic to southern Queensland, Australia.
Westrapyrgus is a genus of minute freshwater snails with an operculum, aquatic gastropod molluscs or micromolluscs in the family Hydrobiidae. The genus is endemic to south Western Australia. It is the first hydrobiid genus to be described from this state.
Caldicochlea is a genus of freshwater molluscs in the family, Tateidae, endemic to the mound springs of the Great Artesian Basin.
Caldicochlea globosa is a species of freshwater mollusc in the family, Tateidae, endemic to the Dalhousie Springs of the Great Artesian Basin. The species was first described in 1996 as Dalhousia globosa by Winston Ponder, Donald Colgan, T. Terzis, Stephanie Clark and Alison Miller. However, the genus name of Dalhousia had already been used, and thus in 1997, Ponder published the replacement genus name of Caldicochlea.
Caldicochlea harrisi is a species of freshwater mollusc in the family Tateidae.
