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.

Low Activity

2009 saw an overall decrease from high activity from 2008, levelling off in the December quarter as the economy stabilised. Unsurprisingly, most activity was in offshore Western Australia and on coal seam methane (CSM) in Queensland. Highlights include: good results in the Carnarvon and Browse basins for Western Australian operators, interest in Karoon and Conoco-Phillips’ enigmatic Poseidon project, over 180 CSM exploration wells in Queenslandd, and a relatively busy year for Tasmania. Western Australian seismic acquisition approached 10,000 km of 2D and 25,000 km2 of 3D for 38* wells and success rate around 50%. South Australia saw the highest conventional onshore drilling and seismic activity, with good results for 17 wells, while other states saw low activity in this sector. Victoria saw one offshore exploration well and no seismic. Tasmania also saw no new seismic, but saw four exploration wells and encouragement at Rockhopper–1. CSM is picking up in South Australia, and New South Wales saw continued high CSM activity in a historically low-activity region. High success rates suggest two trends: explorers finding value in 3D seismic, and a ‘flight to quality’ as operating costs and poorer access to capital reinforce risk aversion among operators. Elsewhere, geothermal energy helped small cap investors satisfy their appetite for risk outside of the petroleum industry, and results will be watched with great interest. *Numbers are from early public and departmental statistics and may be revised.

Flower Growth

Seventy-four lines of Trifolium glomeratum L. from a wide range of Australian and European environments were grown in a glasshouse at Canberra. Time to flower, growth habit, leaf markings, stipule colour, floret colour and dry matter production varied among collections, and within some lines. Numbers of flowers per plant, leaf: stem ratio, and dry matter yields were correlated with days to flower. The variation within the European collection was similar to that within the Australian collection. Time of flowering has probably been important in natural selection in this species, since the date of flowering at Canberra was strongly correlated with date of the end of the growing season (defined by effective rainfall) at the collection site of each ecotype. A survey during 1970 through New South Wales, Victoria and South Australia showed the western limit of spread of T. glomeratum to be through Garah, Burren Junction, Coonamble, Euabalong,Booligal, Moulamein, Beulah, Lake Hindmarsh, Mannum and Jamestown. Extrapolation of climatic restrictions to Western Australia indicated that the species could exist west of Lake Biddy, and possibly north and east to Geraldton and Esperance. The distribution appears to be controlled by the shortest length of growing season in which the species can germinate, grow, and set viable seed.

Original Concept

Digitate-leaved specimens of the genus Glycine from across southern Australia that have been determined as G. clandestina J.C.Wendl. encompass a wide range of morphological variation. Re-evaluation of this material has resulted in the conclusion that three species should be recognised. The original concept of G. clandestina (digitate-leaved plants with long, c. nine-seeded pods) can be applied only to plants from Queensland, New South Wales, Victoria and Tasmania. Two new species, G. peratosa B.E.Pfeil & Tindale and G. rubiginosa Tindale & B.E.Pfeil, are described from Western Australia and South Australia, respectively. Variation in G. clandestina s.s. is discussed in relation to contact zones with three other closely related species.

Unidentified Species

The cosmopolitan oribate mite genus Scheloribates Berlese, 1908 and the Scheloribatidae Grandjean, 1933 are redefined and a new genus, Megascheloribates, is established. Previous scheloribatid records (all unidentified species of Scheloribates) from Australia are reviewed. Records of Megascheloribates, Scheloribates and Setobates Balogh, 1962, from nine florally diverse sites in South Australia, are listed to indicate their possible value as ecological indicators. Records are given of two unidentified Scheloribates species as intermediate hosts of anoplocephalid tapeworms in New South Wales and Victoria indicating that species vary in their susceptibility to infestation. Eleven new species from eight sites in South Australia are described, grouped in three species-complexes of Scheloribates and in Megascheloribates as follows: Scheloribates eusetosus-complex – S. eusetosus, S. brevipodus, S. diforamenatus, S. nanus, S. parabrevipodus, S, parananus; Scheloribates crassipodus-complex – S. crassipodus; Scheloribates heterosetosus-complex – S. hetersetosus, S. unisetosus; Megascheloribates, gen. nov. – M. microsetosus, M. calcaratus. A key is given to distinguish Australian genera of Scheloribatidae and species of Megascheloribates and Scheloribates. Some morphological characters, including leg size and shape, are considered. New synonymies are proposed as follows: Hemileiidae Balogh & Balogh, 1984 under Scheloribatidae; Neoscheloribates Hammer, 1973 and Semischeloribates Hammer, 1973 under Scheloribates; Propescheloribates Jacot, 1936 under Styloribates Jacot, 1934b. The synonymy of Styloribates under Muliercula Coetzer, 1968 by Coetzer, 1968 is revoked. New combinations, previously with Scheloribates, are proposed as follows: Megascheloribates anzacensis (Hammer, 1961); M. giganteus (Hammer, 1967); M. maximus (Balogh, 1962); M. microclava (Balogh, 1962); M. rostrodentatus (Hammer, 1977); Perscheloribates conjuges (Hammer, 1967); P. keriensis (Hammer, 1967); P. monodactylus (Zandalinas, 1987).

A new genus and two new species of miniature clingfishes are described based on specimens collected from dense stands of macroalgae in intertidal and shallow subtidal areas along the coast of southern Australia. The new genus, Barryichthys, is distinguished from other genera of the Gobiesocidae by unique features of the adhesive disc, including elongate papillae in adhesive disc regions A and B, the reduction and/or loss of several elements of the cephalic lateral line canals, the lower gill arch skeleton, and the neurocranium, and by having two distinct types of pectoral-fin rays. Barryichthyshutchinsi is described based on 19 specimens (12.4–18.7 mm SL) from Western Australia and South Australia. Barryichthysalgicola is described based on 22 specimens (9.0–21.0 mm SL) from Victoria, New South Wales and Tasmania. The new species are distinguished from each other by characters of body and head shape, vertebral counts, and aspects of live colour pattern. The new genus shares several characters in common with Parvicrepis, another genus of miniature gobiesocids from southern Australia that also inhabits macroalgae habitats. The many reductions and novel characters of Barryichthys are discussed within the context of miniaturisation.

B. aculeata (Labill.) Less. (New South Wales and Victoria), B. cuneifolia Tate (South Australia), B. sieberi var. gunnii DC. (Tasmania) and B. spathulata Gaudich. ( = B. scapiformis DC.) (New South Wales, Victoria and Tasmania) are names shown to refer to separate species. The two varieties of B. spathulata have been recognized as two subspecies: subsp. spathulata (mainland Australia) and subsp, glabra (Tasmania). All species are n = 9 or polyploid on n = 9. Small B-chromosomes have been found at high frequency in B. sieberi var. gunnii and B. aculeata, but rarely in B. spathulata. Strong genetic barriers separate pairs of sympatric species.

A new genus, Alainchabaudia, is proposed, apparently close to Hartertia, but differing in the presence of modifications of the anterior end of the buccal capsule, which is prolonged dorsally and ventrally and ends in four submedian teeth. Two species are included: the type species, C. alcedinis sp.nov., from Halcyon sanctus (Queensland and South Australia) and Dacelo gigas (New South Wales); and A. aegotheles (Johnston & Mawson) syn. Habronema aegotheles J. & M., from Aegotheles cristata (South Australia).The specimens from Queensland were lent by Dr John Pearson of the School of Parasitology of the University of Queensland. The bodies of the other two birds were sent to me for dissection, Dacelo gigas by Mr H. J. de S. Disney, Curator of Birds in the Australian Museum, Sydney, and Halcyon sanctus by Mr H. Condon, Curator of Birds in the South Australian Museum, Adelaide. I am most grateful to these gentlemen for their assistance.
