AbstractThe geometrid genus Archephanes Turner, which includes one described species, zalosema Turner, is reviewed. Previously thought to be restricted to Tasmania, the genus has a south eastern Bassian distribution, below latitude 36°S. It inhabits the moist forests and sub-alpine regions of south eastern Australia from sea level to over 1000 m. The distinctive and colourful larvae feed exclusively on the foliage of Tasmannia lanceolata (Poiret) A. C. Smith, 1969 (Winteraceae). The life-cycle is described and immature stages illustrated for the first time.

AbstractThe previously overlooked geometrid genus Palleopa Walker, which includes one described, widespread species: innotata, is reviewed. The genus has an eastern Bassian distribution, south of latitude 28°S, in the moist forests and woodlands of south eastern Australia from sea level to over 1000m. The distinctive larvae feed on the foliage of Eucalyptus trees. The immature stages are described and the life cycle is illustrated for the first time.

Callococcithrips gen.n. is erected for the species Rhynchothrips fuscipennis Moulton that lives only among the protective waxy secretions of an eriococcid on Kunzea in south-eastern Australia. Larvae and adults of this thrips move rapidly amongst the sticky wax strands, and their maxillary stylets are unusually long and convoluted. Circumstantial evidence suggests that the thrips is predatory on immature stages of the eriococcid. Also transferred to this genus is Liothrips atratus Moulton, based on a single female from Western Australia.

Using four decades of hydrographic data collected off the coast near Sydney, New South Wales, and sea-level data at Sydney, we studied the interannual variability in south-eastern Australian shelf waters. The first two empirical orthogonal function (EOF) modes of the band-pass-filtered 50-m-depth hydrographic data (temperature, T; salinity, S; nitrate, N; inorganic phosphate, P; and oxygen, O) and the sea level (SL) and adjusted sea level (ASL) data accounted respectively for 51 and 27% of the total variance. Both modes were significantly correlated with the Southern Oscillation Index (SOI). The first mode, with T, S, O and ASL varying in opposition to N and P, represented the internal or baroclinic response, associated with vertical displacements of the isopycnals. The second mode, with large in-phase fluctuations in SL and ASL but small changes in the hydrographic variables, represented mainly the external or barotropic response during the El Niiio-Southern Oscillation (ENSO). Three-year composites centred around seven ENSO warm episodes revealed that T, S, O and ASL were generally low and N, P, SL and SO1 were high in the year before each ENSO warm episode, but the former group rose while the latter group dropped in the year of the warm episode. The changes in the hydrographic variables at 50 m depth were consistent with relatively shallow isopycnals in the year before the ENSO warm episode, followed by a deepening of the isopycnals during the warm episode. Estimates of this downward displacement of isopycnals, as determined from T, N, P and O, were in the range 7-10 m. The geostrophic wind arising from the pressure fluctuations during ENSO is proposed as a probable cause for the vertical displacement of the isopycnals. In the year before the warm episode, the low air pressure over Australia would produce a clockwise geostrophic wind around south-eastern Australia, generating offshore Ekman transport and coastal upwelling. During the warm episode, air pressure over Australia rises, the geostrophic wind reverses, and downward movement of the isopycnals would occur off south-eastern Australia.

Nivicolous myxomycetes were collected from alpine areas of south-eastern Australia during the period of middle to late October 2004. Most collections came from the high-elevation area around Mount Kosciuszko, the highest peak on the continent at 2228 m, in the Snowy Mountains of New South Wales, and additional collections were obtained from two areas, Mount Buller and Mount Hotham, in the Victorian Alps of northern Victoria. Approximately 300 collections were obtained during a period of 2 weeks, including species such as Diderma alpinum, Didymium dubium, Lamproderma ovoideum, Physarum albescens and P. alpinum, not previously known to occur in mainland Australia. Lamproderma maculatum and L. zonatum were collected for the first time in the southern hemisphere, and another species of Lamproderma was described as new to science in a previous paper. In contrast to most other areas of the world where nivicolous myxomycetes have been studied, species of Diderma have been represented poorly among the collections from Australia.

THE spotted-tailed quoll (Dasyurus maculatus) is the largest carnivorous marsupial extant on mainland Australia, where it has a fragmented distribution in forested habitats in the eastern part of the continent. This species is also found in Tasmania. D. maculatus have been found in a wide variety of forest types from sea level to over 1400 m above sea level, in areas generally receiving in excess of 600 mm of rainfall (Mansergh 1983). The distribution of D. maculatus is believed to have declined by over 50% following European settlement (Mansergh 1983).

Notothixos is a genus of eight species distributed from Ceylon, Lower Burma and the Philippines southwards and eastwards through the Malesian region to Santa Cruz Islands and south-eastern Australia. It is distinguished by a dense and conspicuous indumentum of dendritic, stellately branched or peltate hairs or scales, and by lateral stems subtended by two prophylls and two cataphylls. The basic inflorescence unit is a small cymose cluster subtended by a pair of small bracts, and conflorescence evolution has involved the aggregation of cymules, and development of indeterminate conflorescences from determinate ones. The entire genus has not been revised previously; four names are reduced to synonymy of others for the first time here. Notothixos curranii Merrill, N. merguiensis Danser and N. spicatus Krause are conspecific with N. floccosus (Thw.) Hook.f, and N. schlechteri Krause is conspecific with N. leiophyllus Schumann. New chromosome numbers are reported for two species: N. incanus (n= 13) and N. subaureus (n = 12). Evidence suggests that the genus originated in the Malesian region, and that it has reached Papuasia and Australia as part of an intrusive element following Miocene collision of the Australian and Sunda plates.

The larva and pupa of Neureclipsis napaea Neboiss from Australia are described. They conform in most characteristics with Neureclipsis McLachlan larvae and pupae from the northern hemisphere, although the Australian larva differs in the number of setae present on the venter of abdominal segment 9 and on the basal segment of the anal prolegs. N. napaea has been collected from larger upland rivers in south-eastern Australia, where the larva forms a loose silken net suspended between rocks.

A morphometric study was undertaken into alpine and subalpine species of Euchiton Cass. (Gnaphalieae: Asteraceae) in the Euchiton traversii species complex in south-eastern Australia and New Zealand. Phenetic analysis of both field-collected and herbarium specimens resolved the following six taxa included: Euchiton traversii (Hook.f.) Holub, Euchiton argentifolius (N.A.Wakef.) Anderb., Euchiton lateralis (C.J.Webb) Breitw. & J.M.Ward, Argyrotegium mackayi (Buchanan) J.M.Ward & Breitw., Argyrotegium fordianum (M.Gray) J.M.Ward & Breitw. and Argyrotegium poliochlorum (N.G.Walsh) J.M.Ward & Breitw. The results support the segregation of the genus Argyrotegium J.M.Ward & Breitw. from Euchiton. E. argentifolius is distinct from E. traversii, but conspecific with A. mackayi. E. lateralis is present in Tasmania as well as New Zealand. The distribution of Australian E. traversii is redefined to mainland alpine regions with a few rare occurrences in Tasmania. Australian E. traversii was shown to be similar to its New Zealand counterparts. Differences between E. lateralis and E. traversii were clarified. A. fordianum and A. poliochlorum are distinct species and their transfer to Argyrotegium is supported.
