Hyporheic Tateidae (Gastropoda: Truncatelloidea) from the Flinders Ranges, South Australia and Judbarra (Gregory) National Park, western Northern Territory, Australia, with some taxonomic notes on the family.

Four new species of phreatic tateids from stream sediments in Australia are described. One, from intermittent streams in the Flinders Ranges, South Australia, is a highly modified species of Austropyrgus, a genus widespread in south-eastern Australia and Tasmania. The other three species are included in the new genus Turricochlea and live in sympatry in gravel in a creek bed in the Gregory National Park in the western part of the Northern Territory. Molecular analysis showed that Turricochlea and 'Fluviopupa' kessneri are closely related to Sulawesidrobia from Sulawesi but not Fluviopupa, so the new generic name Austropupa is provided for F. kessneri. Two new family names are proposed for taxa previously included in Tateidae: Beddomeiidae and Ascorhiidae. [ABSTRACT FROM AUTHOR]
