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.

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.

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.

The taxonomy of ophiuroids collected in 2009 and 2011, from biogenic habitats across the New Zealand continental shelf, is reviewed. Ophionereis novaezelandiae Mortensen, 1936, and its junior synonym Ophionereis terba Baker & Devaney, 1981from South-Eastern Australia, is now recognised as a distinct species, and has been removed from synonymy with Ophionereis fasciata Hutton, 1872. Ophiacantha abyssicola var. otagoensis Fell, 1958 is also recognised as a distinct spe-cies and has been removed from synonymy with Ophiacantha brachygnatha Clark H L, 1928. Amphiura eugeniae var. latisquama Mortensen, 1924 is raised to species rank and Amphioplus longirima Fell, 1952 treated as a synonym of A. latisquama. Ophiolycus farquhari McKnight, 2003 is transferred to the genus Ophiologimus. The diagnostic characters of several other species are reviewed and colour descriptions and images are included where available. The tropical species Ophiacantha longidens Lyman, 1878, Ophiotreta valenciennesi (Lyman, 1879) and Ophiobyrsa intorta (Koehler, 1922) are reported from New Zealand waters for the first time.

Alpine soil seedbanks are generally regarded as small and unimportant to regeneration. Here, we investigate for the first time the composition of the readily germinable soil seedbank across alpine summits in south-eastern Australia. We aimed to compare the species in the seedbank with the standing vegetation, show seasonal variations in seedbank composition and identify regeneration strategies of alpine seedbank species. By using standard glasshouse and cold-stratification germination techniques, the germinable soil seedbank across the study region was found to comprise 39 species from 25 families, with species from the Asteraceae the most common. Persistent seedbanks were found across all eight alpine summits (1668–1970 m), comparable in seed density (150 ± 27 to 1330 ± 294 per m2) with those of other alpine areas in the northern and southern hemispheres. The density of germinable seeds varied widely among sites and between collection times (autumn, spring) and there were no trends in seed density with altitude. The qualitative and quantitative similarity between the seedbank species and the standing vegetation was low. Correlations between the proportions of species in regeneration categories (from obligate seeders, through to vegetative regenerators) in the standing vegetation and the seedbank were also poor. Our results indicate a divergence between the species in the current standing vegetation and those present in the readily germinable soil seed bank. The current patterns and predominance of seed-regenerating species in the seedbank indicate that these species may have an important role to play in regulating and contributing to future changes in the vegetation assemblage.

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.
