PONDER Australian Museum, 6 College Street, Sydney NSW 2010, Australia 1 current address: Department of Biological Sciences, Biodiversity & Systematics, University of Alabama, Box 870345, Tuscaloosa, AL 35487, Unites States of America [email protected] · [email protected] · [email protected] ABSTRACT. The species that comprise a morphostatic radiation in southeastern Australia of the hydrobiid genus Austropyrgus Cotton are described using shell, opercular, anatomical and radular characters, and the genus is redefined. The previously described taxa have been included under several generic names, including Fluvidona (now a separate genus), Rivisessor, Pupiphryx and Angrobia, which are now treated as synonyms of Austropyrgus. Seventy-four species are described from southeastern Australia, fifty- seven of them new. These are grouped into six informal morphological groups to aid identification. Two recently described outlying species, A. bunyaensis from Mt Bunya, southern Queensland and A. centralia from Dalhousie Springs, northern South Australia, are not included in this revision. Members of the genus are typically found in streams, although a few species live in springs, rivers or lakes. A large number of the species have restricted distributions and several are known only from single locations. In southern New South Wales, Victoria and South Australia Austropyrgus is the dominant native freshwater hydrobiid genus whereas in Tasmania it is often sympatric with the native freshwater hydrobiid genera Beddomeia and/or Phrantela.

  • Phrantela Iredale, 1943
    Phrantela Iredale, 1943 Diagnostic features Shell pupiform to conic to trochiform, small to medium size for family (between about 1.7 and 7.0 mm in maximum dimension). Periostracum thin to well developed, colourless to dark brown. Teleoconch sculpture usually of faint, prosocline growth lines, weak spiral threads sometimes present; periphery of last whorl usually evenly rounded, sometimes subangled, rarely sharply angled. Aperture ovate, inner lip thin and narrow, columellar swelling typically absent (weakly developed in one taxon). Outer lip thin, slightly opisthocline to prosocline. Umbilicus wide to small, or closed and represented by chink. Operculum oval, thin, transparent pale yellow, simple, with eccentric nucleus. Bursa copulatrix in the female genital system reaches to the posterior pallial wall [or (rarely) almost reaches it or extends into the pallial roof] and has the duct emerging from the ventro-posterior comer. This is one of the main anatomical features that distinguishes this taxon from Beddomeia. The pallial genital ducts in both males and females are thinner in section than in Beddomeia and the female genital opening is typically slit-like, rather than a short, pore-like opening. Generally a posterior pallial tentacle is present.

    Zoological Studies 47(3): 338-351 (2008) Multi-Gene Analyses of the Phylogenetic Relationships among the Mollusca, Annelida, and Arthropoda Donald J. Colgan1,*, Patricia A. Hutchings2, and Emma Beacham1 1Evolutionary Biology Unit, The Australian Museum, 6 College St. Sydney, NSW 2010, Australia 2Marine Invertebrates, The Australian Museum, 6 College St., Sydney, NSW 2010, Australia (Accepted October 29, 2007) Donald J. Colgan, Patricia A. Hutchings, and Emma Beacham (2008) Multi-gene analyses of the phylogenetic relationships among the Mollusca, Annelida, and Arthropoda. Zoological Studies 47(3): 338-351. The current understanding of metazoan relationships is largely based on analyses of 18S ribosomal RNA ('18S rRNA'). In this paper, DNA sequence data from 2 segments of 28S rRNA, cytochrome c oxidase subunit I, histone H3, and U2 small nuclear (sn)RNA were compiled and used to test phylogenetic relationships among the Mollusca, Annelida, and Arthropoda. The 18S rRNA data were included in the compilations for comparison. The analyses were especially directed at testing the implication of the Eutrochozoan hypothesis that the Annelida and Mollusca are more closely related than are the Annelida and Arthropoda and at determining whether, in contrast to analyses using only 18S rRNA, the addition of data from other genes would reveal these phyla to be monophyletic. New data and available sequences were compiled for up to 49 molluscs, 33 annelids, 22 arthropods, and 27 taxa from 15 other metazoan phyla. The Porifera, Ctenophora, and Cnidaria were used as the outgroup. The Annelida, Mollusca, Entoprocta, Phoronida, Nemertea, Brachiopoda, and Sipuncula (i.e., all studied Lophotrochozoa except for the Bryozoa) formed a monophyletic clade with maximum likelihood bootstrap support of 81% and a Bayesian posterior probability of 0.66 when all data were analyzed.

Prominent and endangered components of the GAB spring community are snails of the family Hydro- biidae. This paper examines the evolutionary relationships of the entire hydrobiid fauna associated with the GAB, and includes appropriate non-GAB species to place the GAB fauna in a broader phylogenetic context. The Queensland genus Jardinella is a focus of this paper, providing a Wne scale examination of relationships between spring supergroups in the northeastern regions of the GAB. Maximum parsimony and Bayesian analyses performed on 16S, CO1, and combined sequence data from 40 hydrobiid taxa found four major clades of Australian taxa. The analysis revealed that at least three separate colonization events of the GAB spring fauna have occurred. Two of these are represented by considerable radiations, (1) Jardinella to the north and east and (2) Caldicochlea, Fonscochlea, and possibly Trochidrobia in South Australia.

  • Notes on the Glacial Beds of Freestone- Bluff (Sandy Cove) Near Wynyard
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by University of Tasmania Open Access... NOTES ON THE GLACIAL BEDS OF FREE- STONE-BLUFF (SANDY COVE) NEAR WYN- YARD. (PL. IX., X., XL, XII.) By Fritz Noetling, M.A., Ph.D., etc. (Read October i8th, 1909.) (i) HISTORICAL SUMMARY. The first description of the geological features of the coast near Wynyard was given forty years ago by Mr. T. Stephens (i) in a paper read before this Society. In this paper Mr. Stephens drew special attention to the conglomerates at the mouth of the Inglis, and, after mentioning the occurrence of large angular blocks of granite and porphyry, he goes on to say—" These mas- sive blocks of granite and other rocks which are not now found in situ within several miles of their present position, I consider to furnish more conclusive evidence of glacial agency in the geological history of Tasmania ." than I have m^et with elsewhere. As— to the age of this conglomerate, Mr. Stephens says : " It under- lies unconformably the tertiary freestone, which has been determined by Professor IVE'Coy to be of mlbcene age, and it contains boulders derived from rocks which are certainly not older than the lower carboniferous' or Devonian period."' Mr. Stephens was therefore the first to recognise the glacial origin of the " cong"lomerate " near Wynyard, and, though he does not exactly say so, the inference from the above passages is that he considers these beds to be of carboniferous age. Mr. Stephens, though per- haps not the first who advocated a palaeozoic glacial period, was certainly among the first who did so, and.

The species that comprise a morphostatic radiation in southeastern Australia of the hydrobiid genus Austropyrgus Cotton are described using shell, opercular, anatomical and radular characters, and the genus is redefined. The previously described taxa have been included under several generic names, including Fluvidona (now a separate genus), Rivisessor, Pupiphryx and Angrobia, which are now treated as synonyms of Austropyrgus. Seventy-four species are described from southeastern Australia, fifty- seven of them new. These are grouped into six informal morphological groups to aid identification. Two recently described outlying species, A. bunyaensis from Mt Bunya, southern Queensland and A. centralia from Dalhousie Springs, northern South Australia, are not included in this revision. Members of the genus are typically found in streams, although a few species live in springs, rivers or lakes. A large number of the species have restricted distributions and several are known only from single locations. In southern New South Wales, Victoria and South Australia Austropyrgus is the dominant native freshwater hydrobiid genus whereas in Tasmania it is often sympatric with the native freshwater hydrobiid genera Beddomeia and/or Phrantela.
