A new bat-flea from Australia

An account is given of an undescribed bat-flea found in a jar with an alcohol-preserved specimen of the Australian giant false vampire bat and a new genus is erected for its inclusion.     

A nickel-accumulating plant from Western Australia

Summary A small shrub Hybanthus floribundus (Lindl.) F. Muell. Violaceae growing in Western Australia accumulates nickel and cobalt to a very high degree. Values of up to 23% nickel in leaf ash may represent the highest relative accumulation of a metal on record. The high accumulation of nickel poses interesting problems in plant physiology and plant biochemistry.     

A new species of Brachydontium from Australia

Abstract

A new species (Brachydontium intermedium) is described. It is the first record of the genus for Australia and a comparison is made with the other two species, both from the Northern hemisphere.     

A New Species of Riella from Australia

Abstract

Riella halophila Banwell, sp.nov., a salt-marsh or salt-lake plant from Victoria, Australia, is described and figured. The genus being new to Australia, the extension of range is discussed, and other general notes are given.     

A new species of Pleuridium from Australia

Abstract

A new species, Pleuridium curvisetum, is described. It has an arched seta similar to that of P. arnoldii and was collected, sometimes in association with that species, in alpine country in Australia. P. arnoldii was first recorded from New Zealand. A comparison of the two species revealed some features, including a bistratose margin to the leaf subula, not previously reported for P. arnoldii.     

A new species of commensal hoplonemertean from Australia

A new series of hoplonemertean from Australia is described and named Gononemertes australiensis. The morphology of this nemertean, which lives commensally in the ascidian Pyura pachydermatina (Herdman) variety intermedia Herdman, is described and illustrated and its taxonomic placing discussed.     

A Middle Devonian lichid Trilobite from South-Eastern Australia

A new lichid trilobite belonging to the subgenusMephiarges is described from delicately silicified fragments present in a massive Middle Devonian limestone in South-eastern Australia. Previously this subgenus was limited to one species of which only the cephalon is known.     

A pachyosteomorph arthrodire from Gogo, Western Australia

A new monotypic genus of eubrachythoracid arthrodire is described from die Upper Devonian Gogo Formation of Western Australia as Incisoscutum ritchiei gen. et sp. nov. It is at die pachyosteomorph level of organization, having no contact between the plates of die flank and those of the ventral shield behind the pectoral fin. It is interchangeable widi Coccosteus spp. and a number of earlier described Gogo forms in a sketch dadogram for arthrodires, but its phylogenedc relationships are unknown. Well preserved material of die scapulocoracoid throws new light on die structure of this element in arthrodires, particularly widi respect to variations in die pattern of canals and foramina.     

A Common View of the Opportunities, Challenges, and Research Actions for Pongamia in Australia

Interest in biofuels is increasing in Australia due to volatile and rising oil prices, the need to reduce GHG emissions, and the recent introduction of a price on carbon. The seeds of Pongamia (Millettia pinnata) contain oils rich in C18:1 fatty acid, making it useful for the manufacture of biodiesel and other liquid fuels. Preliminary assessments of growth and seed yield in Australia have been promising. However, there is a pressing need to synthesise practical experience and existing fragmented research and to use this to underpin a well-founded and co-ordinated research strategy to support industry development, including better management of the risks associated with investment. This comprehensive review identifies opportunities for Pongamia in Australia and provides a snapshot of what is already known and the risks, uncertainties, and challenges based on published research, expert knowledge, and industry experience. We conclude that whilst there are major gaps in fundamental understanding of the limitations to growth of Pongamia in Australia, there is sufficient evidence indicating the potential of Pongamia as a feedstock for production of biofuel to warrant investment into a structured research and development program over the next decade. We identify ten critical research elements and propose a comprehensive research approach that links molecular level genetic research, paddock scale agronomic studies, landscape scale investigations, and new production systems and value chains into a range of aspects of sustainability.     

A new species of the lichen genusDiploschistes from Australia

Diploschistes hensseniae Lumbsch & Elix is described as new to science. It is characterized by its terricolous habitat, perithecioid closed ascomata, relatively small spores, cylindrical asci, and the presence of diploschistesic and orsellinic acids in addition to lecanoric acid. It occurs on soil in arid regions of Australia.     

A new aquatic species of Verrucaria from alpine Australia

Abstract:Verrucaria cootapatambensis sp. nov. is described from sandstone boulders in an alpine, snow-melt creek in Kosciuszko National Park, New South Wales, Australia. Crown     

A primitive eubrachythoracid arthrodire from Gogo, Western Australia

A new eubrachythoracid arthrodire, Hanytoombsia elegans gen. et sp. nov., is described from the Upper Devonian Gogo formation of Western Australia. Its structure and relationships are discussed within the framework provided by a new sketch cladogram for arthrodires. H. elegans is morphologically similar to Coccosteus cuspidatus , but its relationships among primitive eubrachythoracids are unknown.     

A second eubrachythoracid arthrodire from Gogo, Western Australia

A new genus of long-snouted, eubrachythoracid arthrodire, Camuropiscis gen. nov., is described from the Upper Devonian Gogo formation of Western Australia. It is represented by two species, the type C. concinnus sp. nov. and C. laidlawi sp. nov. These species are interchangeable with Coccosteus spp. in a sketch cladograin for arthrodires; their phylogenetic relationships are not known in any detail. C. concinnus has a well-preserved pelvic girdle and throws new light on the structure of this element in arthrodires.     

A new species of psychrolutid fish from western Australia

Psychrolutes occidentalis, a new species of psychrolutid fish, is described from mud bottoms at depths of 350–740 m on the continental slopes around Rowley Shoals, northwestern Australia. The new species is illustrated and compared with other species of the genusPsychrolutes. It differs from other species in the following characters: 14–15 dorsal soft rays, 21–23 pectoral rays, 30–31 vertebrae, no cirri on head and body, lateral line not emerging through tubes, and reddish brown head and body color with darker brown marblings. Aspects of the zoogeography of this new species from the tropical region and of the other species ofPsychrolutes are discussed.
