Australasian pericomoids, psychodids resembling northern hemisphere species of Pericoma Walker (tribe Pericomini), are mostly members of the tribe Maruinini, here re-defined. Amongst Maruinini, they are like several neotropical genera named by Enderlein (1937), but their actual relationship to Enderlein's genera, and hence their identity, has been a long-standing taxonomic problem. Consideration of extensive new collections and observations made in the southern hemisphere now shows that they consist of the following: Genus Notiocharis Eaton. Tribe Maruinini: genus Didicrum Enderlein, and five new genera, Eremolobulosa, Rotundopteryx, Alloeodidicrurn, Satchellomyia and Ancyroaspis. Of these, the Australian Eremolobulosa is the possible sister group of the European Lobulosa Szabo, and the New Zealand genera Satchellomyia and Ancyroaspis are possible sister groups. Of Enderlein's neotropical genera, five classified by Quate (1963) as synonyms, or in one case a subgenus, of Pericoma (Didicrum, Desmioza, Synmormia, Syntomolaba and Podolepria) are recognised as full genera. A key to Australasian pericomoid genera is provided.

Abstract. We present 60 years of Δ14CO2 measurements from Wellington, New Zealand (41° S, 175° E). The record has been extended and fully revised. New measurements have been used to evaluate the existing record and to replace original measurements where warranted. This is the earliest atmospheric Δ14CO2 record and records the rise of the 14C "bomb spike", the subsequent decline in Δ14CO2 as bomb 14C moved throughout the carbon cycle and increasing fossil fuel CO2 emissions further decreased atmospheric Δ14CO2. The initially large seasonal cycle in the 1960s reduces in amplitude and eventually reverses in phase, resulting in a small seasonal cycle of about 2 ‰ in the 2000s. The seasonal cycle at Wellington is dominated by the seasonality of cross-tropopause transport, and differs slightly from that at Cape Grim, Australia, which is influenced by anthropogenic sources in winter. Δ14CO2 at Cape Grim and Wellington show very similar trends, with significant differences only during periods of known measurement uncertainty. In contrast, Northern Hemisphere clean air sites show a higher and earlier bomb 14C peak, consistent with a 1.4-year interhemispheric exchange time. From the 1970s until the early 2000s, the Northern and Southern Hemisphere Δ14CO2 were quite similar, apparently due to the balance of 14C-free fossil fuel CO2 emissions in the north and 14C-depleted ocean upwelling in the south. The Southern Hemisphere sites show a consistent and marked elevation above the Northern Hemisphere sites since the early 2000s, which is most likely due to reduced upwelling of 14C-depleted and carbon-rich deep waters in the Southern Ocean. This developing Δ14CO2 interhemispheric gradient is consistent with recent studies that indicate a reinvigorated Southern Ocean carbon sink since the mid-2000s, and suggests that upwelling of deep waters plays an important role in this change.

A brief review of the movements of Alpine glaciers throughout the Holocene in the Northern Hemisphere (European Alps) and in the Southern Hemisphere (New Zealand Southern Alps) is presented. It is mainly based on glacier studies where 14C dating, dendrochronology and surface exposure dating with cosmogenic isotopes is used to establish the chronology of advances and retreats of glaciers. An attempt is made to draw some general conclusions on the temperature and climate differences between the Northern and Southern Hemisphere.

AbstractThe genusMycoblastusin cool temperate latitudes of the Southern Hemisphere is reviewed. Eight species are treated in detail:M. bryophilusImshaug ex Kantvilas sp. nov., from Campbell Island and Tasmania;M. campbellianus(Nyl.) Zahlbr.,M. coniophorus(Elix & A.W. Archer) Kantvilas & Elix comb. nov. andM. dissimulans(Nyl.) Zahlbr., all widespread across the austral region;M. disporus(C. Knight) Kantvilas comb. nov., from New Zealand and Tasmania;M. kalioruberKantvilas sp. nov, from Tasmania;M. sanguinarioidesKantvilas sp. nov., from Tasmania and south-eastern Australia; andM. leprarioidesKantvilas & Elix sp. nov., from south-eastern Australia (Victoria). Notes are provided on many other species ofMycoblastus, including those recognised for the Northern Hemisphere, and those originally described from austral regions but now excluded from the genus. Major characters of the genus are discussed, including thallus morphology and chemistry, apothecial pigments and ascus structure. It is suggested that the genus is heterogeneous and that some of its closest affinities may lie with the familyMegalariaceaeand the genusJapewia.

The World

<p>The Mytilus edulis species complex, comprised of M. edulis, M. galloprovincialis and M. trossulus, is antitropically distributed in temperate coastal regions of all oceans and main seas of the world. This genus has been heavily studied in the Northern hemisphere but Southern hemisphere populations have received much less attention. This thesis aims to place Southern hemisphere blue mussels into global evolutionary relationships among Mytilus species and investigate aspects of their molecular ecology, including, effects of non-native Northern hemisphere species introductions, biogeography across the Southern hemisphere, regional phylogeographic patterns and population genetics within New Zealand. Southern hemisphere blue mussel phylogenetic reconstruction resulted in the detection of a monophyletic M. galloprovincialis lineage. Two new molecular markers developed with specificity for this lineage and congruence among phylogenetic investigations indicates a panhemispheric distribution of this M. galloprovincialis lineage with implications for naming a new sibling species of the M. edulis complex. This proposed new species, M. meridianus, is distributed in South America, the Kerguelen Islands, New Zealand and Australia at latitudes between ~ 30°S and ~ 55°S. Non-native M. galloprovincialis introduced from the Northern hemisphere have been present in NZ, Australia and Chile for at least ten years and hybridise with native blue mussels. Introgression is observed in New Zealand and Australian but not Chilean hybrid regions. The limited number of introduced mussels in Australia induces hybrid swamping of non-native alleles but an interlineage gender bias towards non-native maternal parents may result in eventual loss of the unique genomic content of native blue mussels in NZ. Southern hemisphere blue mussels form a monophyletic sister clade to a haplogroup shared by Northern hemisphere M. edulis and M. galloprovincialis. Although single gene histories are not congruent with respect to evolutionary relationships within the Northern hemisphere due to introgressive hybridisation after speciation, it is clear that Southern hemisphere blue mussels arose from a species native to the northeast Atlantic Ocean after speciation of the three ‘M. edulis complex’ members. Within the Southern hemisphere monophyletic clade lies three reciprocally monophyletic clades restricted to the geographic regions South America/Kerguelen Islands, New Zealand and Australia. Phylogeographic analysis indicates past gene flow between South American/Kerguelen Islands and New Zealand populations that has ceased at present day and ongoing gene flow between South America and the Kerguelen Islands likely via the West Wind Drift. Within NZ, population subdivision inferred from mtDNA indicates genetic variation is distributed within an east-west phylogeographic split on the North Island. These populations experienced gene flow in the past that has ceased at present day. Microsatellite allele frequencies indicate a different population subdivision within the northwest North Island that has been narrowed down to a 15 km stretch of coastline in a sheltered bay. The abrupt discontinuity within a small geographic area does not conform to classic population subdivision in this broad-cast spawning species, therefore, further investigation into the genomic content of northwest North Island mussels with respect to introgressed non-native genes is warranted. Resolving complex phylogenetic patterns from interspecific introgression is key to understanding the evolutionary history of Southern hemisphere M. galloprovincialis. Further characterisation of hybrid introgression would increase accuracy of (1) inferences of processes contributing to hybridisation dynamics and (2) population subdivision in NZ. Probing the basis for variation of hybridisation dynamics would help to predict the outcomes of Northern hemisphere M. galloprovincialis introductions in other areas of the world.</p>

To Receive

Two new genera, Plesiothele and Bymainiella, are erected to receive all the Australian species of the subfamily Hexathelinae, which now comprises four genera, including Hexathele with 20 species from New Zealand, and Scotinoecus with two species from South America. Plesiothele is a monotypic Tasmanian genus, type-species Hexathele fentoni Hickman, 1936. Bymainiella comprises 12 new species: B. boycei, B. boydi, B. brindabella, B. cannoni, B. grayi, B. lugubris, B. monteithi, B. montisbossi, B. otwayensis, B. polesoni, B. tubrabucca and B. variabilis; also B. montana (Hickman, 1927), and B. terraereginae (Raven, 1976), the latter being the type-species. The typespecies of Scotinoecus, S. cinereopilosus, is redescribed, and keys to the genera of the subfamily Hexathelinae, and to the Bymainiella species, are given. Two new indices are introduced to overcome the problem of bilateral variability. Bymainiella is believed to be the sister group of Scotinoecus.

Currently the computation of mean positions and proper motions for the International Reference Stars (IRS) is hampered by large variations in the observational histories of the stars and lack of overlap between the magnitudes of the IRS and of the FK4. The poorest IRS observational histories are +60° to +80° in the north and −40° to −80° in the south. The much-needed extension of the fundamental system to the ninth magnitude will be made in the FK5. The Faint Fundamental Extension is currently being selected at the U. S. Naval Observatory. A proposed list of 1030 Faint Fundamental stars has been prepared for the Northern Hemisphere, and work has begun on the selection in the Southern Hemisphere.

AbstractSixteen species of lichenicolous fungi are documented fromSiphula-like lichens. Two new genera based on new species are introduced.AmylogallaSuija, Motiej. & Kantvilas, characterized by I+ blue, K/I+ violet vegetative hyphae and ascomatal wall, immersed, cleistohymenial, yellowish to orange ascomata, unitunicate, non-amyloid, 8-spored asci and hyaline, ellipsoid, aseptate ascospores, is described fromParasiphulain Tasmania.SaaniaZhurb., characterized by superficial, stromatic, multilocular ascomata, non-amyloid hymenial gel, persistent periphysoids, bitunicate, non-amyloid, 4(–8)-spored asci and narrowly obovate to ellipsoid, 1(–3)-septate, initially hyaline and smooth-walled, later sometimes brown and verruculose ascospores, is described fromSiphulain South Africa. Four additional species are described as new: two fromSiphula(Cercidospora santessoniiMotiej., Zhurb., Suija & Kantvilas andStigmidium kashiwadaniiZhurb.) and two fromParasiphula(Endococcus hafellnerianusMotiej., Suija & Kantvilas andPyrenidium macrosporumMotiej., Zhurb., Suija & Kantvilas). Additional hosts and/or expanded geographical ranges are reported forAabaarnia siphulicola,Epigloea soleiformis, Plectocarpon gayanumandPyrenidium actinellum. The Southern Hemisphere is the centre of species richness for siphulicolous fungi, with 12 species restricted to this region. Taxa recorded for the Northern Hemisphere areSphaerellothecium siphulae(arctic and boreal) and the subcosmopolitanEpigloea soleiformisandPyrenidium actinellum, both of which are also known from various lichen hosts. The distribution of siphulicolous fungi strongly underpins the current generic classification ofSiphula-like lichens, with five species being confined exclusively toParasiphulaand nine toSiphula. A key to the taxa occurring onSiphulaandParasiphulais provided.

The status of the genus Tricholomopsis (Agaricales) in New Zealand is reviewed. T. rutilans is a species described from the northern hemisphere and recorded from plantations of exotic Pinus radiata in New Zealand. Historical collections identified as T. rutilans were subjected to morphological and phylogenetic analysis. The results show that most of these collections refer to T. ornaticeps, originally described from New Zealand native forests. The presence in New Zealand of T. rutilans was not confirmed. Collections of Tricholomopsis from native forests and bush also include a newly described species, T. scabra, which is characterised by a distinctly scabrous pileus. The new species is phylogenetically and morphologically distinct but related to T. ornaticeps. T. ornaticeps and T. scabra are currently known only from New Zealand and the former has extended its habitat to include exotic conifer plantations.

The species of Massalongia recorded and described from the Southern Hemisphere are revised and it is shown that only one is present; M. patagonica which is widespread, with populations in Australia and New Zealand that differ from the South American populations, but at present best regarded as part of the variation of that species. Records from this hemisphere of all other species placed in the genus are incorrect. The type species, M. carnosa, is restricted to the Northern Hemisphere. Two species, M. antarctica and M. novozelandica cannot be identified precisely due to lack of sufficient type material and with the types as the only collections known of these, but none belongs in Massalongia according to available data. Massalongia griseolobata (from Gough Isl.) is shown here to belong in the Pannariaceae and is part of the parmelielloid clade. M. intricata (from South Georgia) and M. olechiana (from South Shetland) have both recently been correctly transferred to the genus Steinera in the Arctomiaceae.
