Abstract: The estuarine hydrobiid genus Tatea is found throughout temperate Australia. Two, often sympatric, species, T. rufilabris and T. huonensis are recognised, both ranging from southern Western Australia to southern Queensland. Whereas no single anatomical character differentiates the two species, they can be separated on their shell morphology there are up to three fixed, or nearly fixed, differences among 16 loci between sympatric populations of the two species. Geographic variation in both phenotype (expressed in shell morphology) and genotype (allozymes) which is present in T. rufilabris is not great enough or sufficiently consistent to imply the presence of multiple cryptic species within this taxon. Genotypic differences do, however, suggest the possibility of sub ision of T. huonensis into eastern and southern populations. Investigation of salinity tolerances shows that the two species are euryhaline with a similar range of tolerance. The anatomy and egg capsules are described for the first time. Autapomorphies distinguishing Tatea from related Australasian genera include a protoconch indicating a free-swimming (lecithotrophic?) larval stage, a black pigment ring near the distal ends of the cephalic tentacles, and a female genital opening located beneath the middle of the capsule gland. A scenario is presented which may account for the apparent lack of speciation in estuarine animals in temperate Australia.

Abstract: A radiation of hydrobiid snails is described from caves at Precipitous Bluff, southern Tasmania. The radiation (10 species) comprises two closely related genera Pseudotricula, endemic to the Precipitous Bluff caves, and Nanocochlea found in these caves and surface streams and seepages, but also known from elsewhere in southern Tasmania. Two Precipitous Bluff species of Nanocochlea inhabit streams outside the caves, while one is found within the caves all three are new. Seven species of Pseudotricula are described, six being new. Up to five species, one Nanocochlea and four Pseudotricula, are found in single stream habitats characterised by erse sediment and slow to moderate flows. One Pseudotricula species is found in a swifter, larger stream with cobbles and gravel and another on smooth limestone surfaces in fast flowing water and water falls. A cladistic analysis (based on morphology) confirmed the monophyly of Pseudotricula, but the monophyly of Nanocochlea is less robust.

Abstract: The Great Artesian Basin (GAB) of Australia underlies some of the driest parts of South Australia and Queensland and feeds numerous freshwater springs. Prominent and endangered components of the GAB spring community are snails of the family Hydrobiidae. 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 fine 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. The phylogenetic position of the latter is uncertain so it may represent yet another invasion. The third definite invasion is represented by a single species of the speciose SE Australian genus Austropyrgus in the Dalhousie Springs in South Australia. Jardinella is found to be monophyletic, and with one exception, its members in each of the Queensland spring supergroups are found to be monophyletic.

Abstract: A new genus, Cryptassiminea, is introduced for the taxon previously known as Assiminea buccinoides (Quoy & Gaimard). These small gastropods are abundant in mangrove and salt marsh habitats in south-eastern and subtropical eastern Australia. Seven species (five new) are recognised using morphological characters in the complex previously treated as a single species. Five taxa have rather narrow ranges while the other two are widespread and often sympatric. Two groups of species are recognised. One contains Cryptassiminea buccinoides, widespread in south-east and east Australia, and two closely related allopatric taxa from South Australia and south-eastern Tasmania (C. adelaidensis, sp. nov. and C. kershawi, sp. nov.). A second group of species is typified by Cryptassiminea tasmanica (Tenison-Woods), also widespread in east and south-east Australia and often sympatric with C. buccinoides. Allied to C. tasmanica, are two closely related taxa from western Victoria: C. glenelgensis, sp. nov. from the Glenelg River estuary and C. surryensis, sp. nov. from the Surry River estuary and Western Port, in the vicinity of Geelong. A distinctive species, Cryptassiminea insolata, sp. nov. from the east coast of Queensland, also has similarities with C. tasmanica. A cladistic analysis using morphological characters of the Cryptassiminea taxa and three other genera of Assimininae, with an omphalotropidine as the outgroup, resulted in a single tree. The new genus has rather poor support, possibly because many of its characters appear to be plesiomorphic within Assimineinae. Cryptassiminea is defined by a unique combination of characters but lacks any obvious synapomorphy. Two clades within Cryptassiminea are well supported, each containing the species-groups referred to above.

Abstract: An established population of the eastern North American freshwater snail Lymnaea (Pseudosuccinea) columella Say is reported from Middle Creek and Centennial Park, Sydney. This species is an important intermediate host of the liver fluke (Fasciola hepatica Linné) and its introduction and spread in New Zealand has resulted in an increase in the liver fluke problem in New Zealand.

Abstract: We examined the species groups relationships of the freshwater snail genus Austropeplea using mitochondrial, nuclear and morphological markers in addition to traditional methods of shell shape analysis. Based primarily on the results of a combined molecular and morphological analysis, s les of the nominal species A. tomentosa form distinct lineages. The New Zealand populations of A. tomentosa are a very distinct lineage from any of the Australian populations attributed to A. tomentosa. Furthermore, within the Australian group, three lineages, south Australia, Tasmania and eastern Australia, appear to have undergone recent and/or rapid speciation events. S les assigned to A. lessoni were resolved as two distinct lineages, representing the eastern and northern Australian populations. Kutikina hispida was resolved within the Australian A. tomentosa clade. Molecular results for A. viridis suggests that it is also composed of at least two distinct lineages that could be treated as species. Incongruence observed between the single mitochondrial, nuclear and morphological topologies highlight the importance of using a number of different datasets in the delimitation of species-group taxa.

Abstract: Population differentiation and speciation in freshwater snails in a small geographic area were investigated in a study of the morphology and genetics of 75 populations of hydrobiid snails from streams on Wilsons Promontory, Victoria, Australia. At least four genetically definable species occur in sympatry. One (Fluvidona recta sp. nov.) is genetically isolated from the others and the other three (of which only F: turbata sp. nov. is named) appear to be closely related and distinguished by a nearly fixed allozyme (MPI) difference. Heterozygote frequencies for the diagnostic Mpi locus fall well below Hardy-Weinberg expectations in zones of sympatry. There is significant population sub ision within at least two of the genetic species, but as the partitions are allopatric they are not categorised taxonomically. The situation may be explained by the ergence of upland and lowland populations when sea levels fell during the Pleistocene with subsequent secondary contact and low levels of hybridisation in the contact zones. Generally, there is very low gene flow between even closely adjacent populations and extremely low flow between different catchments, F-ST between populations within the same tributary ranging from 0.02 to 0.14 and within adjacent tributaries of the same catchment ranging from 0.03 to 0.59. Some correlations between allozyme data and measured environmental variables were observed but none of these were consistent over all taxa. Size (shell length) appears to be influenced by environment, but shell shape and the length of the opercular smear are more correlated with genetic patterns. A notable lack of correlation between anatomy and genetic groupings was found, although there was some with shell and opercular morphology. Two additional species (F: gippslandica, sp. nov. and F: foris, sp. nov.) from areas adjacent to the Promontory are used as outgroups.

Abstract: Odontophoral cartilages are located in the molluscan buccal mass and support the movement of the radula during feeding. The structural ersity of odontophoral cartilages is currently known only from limited taxa, but this information is important for interpreting phylogeny and for understanding the biomechanical operation of the buccal mass. Caenogastropods exhibit a wide variety of feeding strategies, but there is little comparative information on cartilage morphology within this group. The morphology of caenogastropod odontophoral cartilages is currently known only from dissection and histology, although preliminary results suggest that they may be structurally erse. A comparative morphological survey of 18 caenogastropods and three noncaenogastropods has been conducted, s ling most major caenogastropod superfamilies. Three-dimensional models of the odontophoral cartilages were generated using X-ray microscopy (micro-CT) and reconstruction by image segmentation. Considerable morphological ersity of the odontophoral cartilages was found within Caenogastropoda, including the presence of thin cartilaginous appendages, asymmetrically overlapping cartilages, and reflexed cartilage margins. Many basal caenogastropod taxa possess previously unidentified cartilaginous support structures below the radula (subradular cartilages), which may be homologous to the dorsal cartilages of other gastropods. As subradular cartilages were absent in carnivorous caenogastropods, adaptation to trophic specialization is likely. However, incongruence with specific feeding strategies or body size suggests that the morphology of odontophoral cartilages is constrained by phylogeny, representing a new source of morphological characters to improve the phylogenetic resolution of this group.

Abstract: Although phylogenetic studies are increasingly utilizing multi-locus datasets, a review of GenBank data for the Gastropoda indicates a strong bias towards a few short gene fragments (most commonly COI, LSU rRNA, and SSU rRNA). This is particularly the case for the Rissooidea, one of the largest and most taxonomically difficult gastropod superfamilies. Here we analyze fragments of these three genes from 90 species to determine whether they can well resolve higher relationships within this superfamily, whether structurally aligned sequence datasets increase phylogenetic signal, and whether the inclusion of highly variable regions introduces noise. We also used the resulting phylogenetic data in combination with morphological/anatomical evidence to re-evaluate the taxonomic status of 'hydrobioid' family-level groups. Our results indicate that all three of the alignment strategies that were used resulted in phylogenies having similar signal levels. However, there was a slight advantage to using structural alignment for inferring family-level relationships. Moreover, the set of 'standard' gastropod genes supported recognition of many previously recognized families and provides new insight into the systematics of several problematic groups. However, some family-group taxa were unresolved and the relationships among families were also poorly supported, suggesting a need for more extensive s ling and inclusion of additional genes.

Abstract: The morphology of the abundant brackish-water hydrobiid snail known as 'Hydrobia buccinoides' is described. A new genus, Ascorhis, is provided for it and the valid species name for the southern (South Australia, Victoria, Tasmania) and eastern (New South Wales, Queensland) populations is shown to be victoriae T. Woods. The species name buccinoides is based on Assiminea tasmanica and is an earlier name for that species. Morphological and allozyme differences indicate that the Western Australian populations should be distinguished as a separate species and a new name (A. occidua) is provided for these. Both species show a considerable intrapopulation variation in shell sculpture. Salinity tolerance experiments on three Sydney populations indicate that Ascorhis victoriae tolerates a wide range of salinities, the middle of the preferred range being about that of normal seawater.

Abstract: The Hydrobiidae of Lord Howe Island consist of three genera and nine species. Two species can be ided into two subspecies and one species into five subspecies. The total number of species-group taxa is 15. It is suggested that this fauna is the result of three separate colonizations during the late Tertiary or Pleistocene. Most of the species live in streams, one is adapted to living on waterfalls, and another is subterranean in habit. Hemistomia Crosse contains six species. One, Bythinella whiteleggei Brazier, is probably extinct and two others are restricted to the summit of Mt Cower. A fourth species can be separated into two subspecies, both previously undescribed. One new species is subterranean in habit. Fluviopupa Pilsbry contains two species, one with two subspecies and the other with five, three of the subspecies being new. The remaining genus group, tentatively referred to Potamopyrgus Stimpson, contains only one species [P. oscitans (Iredale)] which is found living on waterfalls. There are seven species pairs on the island, which show a size ratio of 1.3-1.8, suggesting that character displacement (size) may have occurred.

Abstract: In many parts of the world, access to groundwater is needed for domestic, agricultural and industrial uses, and global groundwater exploitation continues to increase. The significance of groundwater in maintaining the health of rivers, streams, wetlands and associated vegetation is often underestimated or ignored, resulting in a lack of scrutiny of groundwater policy and management. It is essential that management of groundwater resources considers the needs of natural ecosystems, including subterranean. We review the limited Australian literature on the ecological impacts of groundwater overdraft and place Australian information within an international context, focusing on lentic, lotic, stygobitic and hyporheic communities as well as riparian and phreatophytic vegetation, and some coastal marine ecosystems. Groundwater overdraft, defined as abstracting groundwater at a rate which prejudices ecosystem or anthropocentric values, can substantially impact natural communities which depend, exclusively or seasonally, on groundwater. Overdraft damage is often underestimated, is sometimes irreversible, and may occur over time scales at variance to those used by water management agencies in modelling, planning and regulation. Given the dangers of groundwater overdraft, we discuss policy implications in the light of the precautionary principle, and make recommendations aimed at promoting the conservation of groundwater-dependent ecosystems within a sustainable use context.

Abstract: A total of 67 taxa, forming part of a major radiation of freshwater hydrobiid snails in Tasmania and eastern Victoria, are described. Four genera are recognised within the radiation: Beddomeia (47 taxa), Phrantela (13 taxa), Nanocochlea, gen. nov. (three taxa) in Tasmania and Victodrobia, gen. nov. (four taxa) in eastern Victoria. Fifty-nine of the species-group taxa are newly described, three of these being given subspecific status. Species-group taxa are separated using morphological data based on 78 characters from the shell, radula, non-genital and genital anatomy. In idual taxa appear to occupy a rather small range of habitats, although within the radiation species are found in many different environments ranging from large rivers to tiny seeps and springs or caves. Nearly all taxa occupy very small geographic ranges, 38 being known only from single localities. Maps indicating the distributions of described taxa and additional populations with similar shell morphologies (but otherwise unworked) are presented. A preliminary phylogenetic hypothesis based on a cladistic analysis, and an overview of the biogeography of the group are presented and conservation considerations are discussed.

Abstract: Helicarionidae is a erse and widely distributed group whose delineation and phylogenetic relationships are poorly understood. We review the helicarionid fauna of Australia (excluding Lord Howe Island and Norfolk Island) and carry out a phylogenetic analysis based on 54 morphological characters. The morphology of 22 Australian helicarionid species from 17 genera is described, including one new genus (Stanisicarion) and two new combinations (Stanisicarion freycineti, Stanisicarion virens). The taxonomic positions of the remaining Australian genera are discussed. In addition, morphological descriptions of 24 taxa closely related to Helicarionidae are presented. Morphological characters indicate that Euconulidae (with subfamilies Euconulinae and Microcystinae), Trochomorphidae and Cystopeltidae can be excluded from Helicarionoidea, supporting recent phylogenies based on molecular data. The Helicarionidae is redefined and most endemic Australian mainland taxa previously assigned to Euconulinae, Durgellinae and Sesarinae can be included within the family as redefined. Five Australian genera (Coneuplecta, Euconulus, Turrisitala, Wilhelminaia and Queridomus) are moved to Euconulinae, one (Liardetia) to Microcystinae and one (Theskelomensor) to Trochomorphidae, leaving 24 genera and 47 species of mainland Australian Helicarionidae. Our results show poor support for the monophyly of Helicarionidae and no synapomorphies can be identified. Helicarionoidea, which is monophyletic in some other recent morphological and molecular analyses, is supported by the shared presence of a flagellum with glandular walls and an axial filament and the presence of an epiphallic retractor caecum. However, one or both of these characters are missing in some helicarionoid taxa. Morphological characters alone give little support for branching patterns among the Australian taxa. This is partly due to high levels of convergence and loss in the data.

Abstract: The freshwater snail genus Fluvidona (Gastropoda, Caenogastropoda, Rissooidea, Hydrobiidae) is reapprasied and described using anatomical, shell, radula and opercular characters. Five species, three of them new, are described, being differentiated using anatomical, shell and opercular character states. A sixth species, similar to the Fluvidona species, is described and is tentatively assigned to the genus Austropyrgus Cotton. All six species live in northern New South Wales and southern Queensland and all are from single localities or very restricted areas. All species live in small streams, although one was found aestivating in soil in the bed of a small dry creek. The new species placed in Austropyrgus, from the Bunya Mountains, Queensland, is widely separated from putative congeners that are found in southern New South Wales and other parts of south-eastern Australia.

Abstract: The Rissooidea is one of the largest and most erse molluscan superfamilies, with 23 recognized Recent families including marine, freshwater and terrestrial members. The Cingulopsoidea are a group of three marine families previously included within the Rissooidea. A previous molecular analysis including two rissooideans and one cingulopsoidean, indicated the possibility that the Rissooidea is at least diphyletic. We use new molecular data to investigate the polyphyly of Rissooidea and test the monophyly of Cingulopsoidea with a greatly increased taxon set. This study includes the greatest s ling to date with 43 species of 14 families of Rissooidea and all families of Cingulopsoidea. Bayesian and maximum likelihood analyses of 16S and 28S show that there are two major clades encompassing taxa previously included in Rissooidea. These are the Rissooidea s.s. containing Rissoidae and Barleeiidae and the Truncatelloidea containing Anabathridae, Assimineidae, Falsicingulidae, Truncatellidae, Pomatiopsidae, Hydrobiidae s.l., Hydrococcidae, Stenothyridae, Calopiidae, Clenchiellidae, Caecidae, Tornidae, and Iravadiidae. Rissoidae is not monophyletic, with Lironoba grouping with Emblanda (Emblandidae) and Rissoina forming a separate clade with Barleeiidae. Iravadiidae is not monophyletic, with Nozeba being sister to the Tornidae. Tatea, usually included within Hydrobiidae, is distinct from that family and Nodulus, previously included in Anabathridae, groups with the hydrobiids.

Abstract: The taxonomy of the pulmonate superfamily Amphiboloidea is investigated with particular reference to Australasian taxa. Anatomical features of the alimentary, reproductive and central nervous systems differ substantially between taxa, and conchological, opercular and radular characters are also described. Four genera are recognised in Amphibolidae Amphibola Schumacher, 1817, Salinator Hedley, 1900, Lactiforis gen. nov. and Naranjia gen. nov.. Two additional genera are assigned to new families Phallomedusa gen. nov. (Phallomedusidae fam. nov.) and Maningrida gen. nov. (Maningrididae fam. nov.). Phallomedusidae fam. nov. is characterised by a paucispiral, keeled operculum and syntremous diaulic reproductive system with a complex, spiral penis. Maningrididae fam. nov. has an expanded operculum with a marginal nucleus and a syntremous diaulic reproductive system with two novel copulatory structures at the genital aperture. Taxonomic descriptions and a key are provided for eight Australian species Salinator fragilis (Lamarck, 1822), Salinator tecta sp. nov., Salinator rh hidia sp. nov., Salinator rosacea sp. nov., Lactiforis tropicalis sp. nov., Phallomedusa solida (Martens, 1878), Phallomedusa austrina sp. nov., and Maningrida arnhemensis sp. nov. and three non-Australian taxa Amphibola crenata (Martyn, 1786), Lactiforis takii (Kuroda, 1928) and Naranjia cf. swatowensis (Yen, 1939).

Abstract: New morphological, ultrastructural, and molecular techniques have reinvigorated interest in molluscan ersity and phylogeny in Australia. Research in the last two decades has revealed a large fauna of small gastropods, including over 260 species of Hydrobiidae. Many are confined to small areas, including springs associated with the Great Artesian Basin. New members of other snail families, notably the Viviparidae and Bithyniidae, have been found in northern Australia. River regulation has decreased the range and abundance of once common species, particularly in the Murray-Darling Basin. While only four freshwater mollusc taxa are officially recognized as “endangered,” several others would qualify and many warrant protection. Investigations of systematics, ecology and biology are urgently needed to facilitate conservation of freshwater molluscs in Australia.

Abstract: Caenogastropoda is the dominant group of marine gastropods in terms of species numbers, ersity of habit and habitat and ecological importance. This paper reports the first comprehensive multi-gene phylogenetic study of the group. Data were collected from up to six genes comprising parts of 18S rRNA, 28S rRNA (five segments), 12S rRNA, cytochrome c oxidase subunit I, histone H3 and elongation factor 1alpha. The alignment has a combined length of 3995 base positions for 36 taxa, comprising 29 Caenogastropoda representing all of its major lineages and seven outgroups. Maximum parsimony, maximum likelihood and Bayesian analyses were conducted. The results generally support monophyly of Caenogastropoda and Hypsogastropoda (Caenogastropoda excepting Architaenioglossa, Cerithioidea and C anilioidea). Within Hypsogastropoda, maximum likelihood and Bayesian analyses identified a near basal clade of nine or 10 families lacking an anterior inhalant siphon, and Cerithiopsidae s.l. (representing Triphoroidea), where the siphon is probably derived independently from other Hypsogastropoda. The asiphonate family Eatoniellidae was usually included in the clade but was removed in one Bayesian analysis. Of the two other studied families lacking a siphon, the limpet-shaped Calyptraeidae was associated with this group in some analyses, but the tent-shaped Xenophoridae was generally associated with the siphonate Strombidae. The other studied hypsogastropods with an anterior inhalant siphon include nine families, six of which are Neogastropoda, the only traditional caenogastropod group above the superfamily-level with strong morphological support. The hypotheses that Neogastropoda are monophyletic and that the group occupies a derived position within Hypsogastropoda are both contradicted, but weakly, by the molecular analyses. Despite the addition of large amounts of new molecular data, many caenogastropod lineages remain poorly resolved or unresolved in the present analyses, possibly due to a rapid radiation of the Hypsogastropoda following the Permian-Triassic extinction during the early Mesozoic.

Abstract: Species from artesian springs associated with the Queensland Great Artesian Basin that were previously included in the tateid genus Jardinella are included in three new genera, namely Eulodrobia, with six species, five of them new and all from the Eulo Supergroup Springvalia, with one species from the Springvale Supergroup and Carnarvoncochlea with two previously-described species, from the Carnarvon Supergroup. The genus Edgbastonia is extended to include eight previously described species, in addition to the type species, and four new species-group taxa from the Barcaldine Supergroup springs all but the type species are included in the new subgenus Barcaldinia. Three new species from non-artesian springs in north Queensland are included in Edgbastonia, one of them tentatively. Two additional related new genera, both with a single new species, are described from outside the Great Artesian Basin Conondalia from southeast Queensland and Nundalia from north-eastern New South Wales. The genus Jardinella, previously used for all the Queensland spring tateids, is here restricted to three species found in coastal rivers and streams in northeast Queensland. A molecular phylogenetic analysis using COI and 16S mitochondrial genes in combination suggests that the Queensland Great Artesian Basin taxa may be more closely related to the tateid genera Austropyrgus, Pseudotricula, Posticobia and Potamopyrgus than to the South Australian GAB taxa, thus indicating the separate origins of these two desert spring faunas.

Abstract: The systematics and distributions of the Recent species of the cerithioidean genus Diala are described. These small marine gastropods are confined to the Indo-West Pacific. Most are very widespread and have protoconchs which suggest that they possess planktotrophic larvae. Of the 30 available names, seven [D. semistriata (Philippi), D. albugo (Watson), D. suturalis (Adams), D. sulctfera Adams, D. sulcifera scobina (Laseron), D. sulcifera martensi (Issel) and D. lirulata Thiele] are recognised as valid, and one species (D. megapicalis, sp. nov.), from southern and western Australia, is described as new. All taxa are variable in shell characters such as colour pattern and size. An annotated list of all taxa originally described as Diala is provided.
