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

ABSTRACT

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.

For the SEM work on the Judbarra/Gregory National Park species we thank Geoff Avern, and the Flinders Ranges SEM work was done by Alison Miller. Stephanie Clark generated the new sequences. We are particularly grateful to Remko Leijs, South Australian Museum, who kindly provided samples of Austropyrgus coolingi n. sp., including the type material. Facilitated by Michelle Guzik and Remko Leijs, Amelia Lewis kindly provided two sequences of Austropyrgus cooling that were part of her honours project at the University of Adelaide (Lewis 2014). We are indebted to Vince Kessner, George (Buz) Wilson, Julie Ponder, Alison Miller, and Des Beechey for help with field work. We are also grateful to Mrs Doris Shearman for her edits on the manuscript. We thank the anonymous reviewers for comments on an earlier version of the manuscript.
