An analysis of the place of 'foreign' Pacific Islanders in the development of North-Eastern Australia and Eastern New Guinea, 1863-1878

Phylogenetic analysis of melanotaeniid mtDNA cytochrome b and tRNA Pro-control region sequence is broadly consistent with the current taxonomy. However, the molecular phylogeny supports the elevation of M. s. australis to full species status and indicates either that it is a composite species or has introgressed with sympatric Melanotaenia species. Phenotypically cryptic mtDNA diversity in north-eastern Australia possibly represents an undescribed species. Six major monophyletic clades present in the phylogeny were strongly supported by morphological data. The clades represent three biogeographic regions. Fish from northern New Guinea form a monophyletic clade, within which Melanotaenia and Glossolepis are polyphyletic. The divergence of this clade from those in southern New Guinea is consistent with the final uplift of the Central Highlands 5 million years BP. North-western New Guinea and associated islands represent another highly divergent, monophyletic clade of a similar age to that in northern New Guinea. The remaining four clades form a monophyletic assemblage restricted to southern New Guinea and Australia: one in northern Australia, one with a disjunct distribution in north-western and eastern Australia, one widespread throughout Australia and southern New Guinea, and one in southern New Guinea with an outlying species in northern Australia. The phylogenetic relationships between Australia and southern New Guinea are consistent with episodic connection via the freshwater Lake Carpentaria during periods of low sea level.

Plant Families

This work presents the first hypothesis of phylogenetic relationships among all 40 genera of the treehopper tribe Terentiini (Hemiptera : Membracidae : Centrotinae). This phylogeny, based on a parsimony analysis of 77 morphological characters, made possible an analytical approach to determining the likely ancestral host-plant family and geographic distribution of the tribe, based on present-day hosts and distributions. Of Australia’s 37 treehopper genera, 36 belong to the tribe Terentiini, with their centre of diversity in Queensland (30 genera). Optimisations of present-day distributions mapped on our phylogeny suggest that the ancestor of the tribe occurred in the Australian region, around north-eastern Australia (Queensland) and New Guinea (which has 8–10 terentiine genera). Subsequent dispersals from the Australian region (with 37 genera) took the tribe to the Indomalayan (11 genera) and Palaearctic (1 genus) regions. At least 13 terentiine genera include representatives that occur beyond the borders of Australia and New Guinea. Notable among the migrant lineages is the clade ‘Polonius + (Bulbauchenia + (Funkhouserella + Pyrgonota))’, which includes genera with such extraordinary pronotal modifications that some members were previously placed in separate tribes (Bulbaucheniini or Funkhouserellini). Members of this remarkable breakaway clade are known from Australia (Polonius only), Indonesia, the Malay Peninsula, Thailand, the Philippines, southern China (Taiwan and Hainan Island) and Japan. With regard to terentiine host plants, optimisations of present-day host associations point to the Leguminosae as the ancestral host family, even though plant families of Gondwanan origin, especially Myrtaceae and Proteaceae, are also prominent terentiine hosts. The overall evidence to date indicates that Terentiini are not a remnant of the early Gondwanan fauna, but rather a more recent tribe derived from Indomalayan ancestors.

Critical Notes

This first series of studies in the Cunoniaceae offers revisions of the genera Ceratopetalum Sm., Gillbeea F. Muell., Aistopetalum Schltr., and Calycomis D. Don. Full synonymy, bibliography, descriptions, and critical notes are given for the genera and species, and keys to the species are included. The genus Cemtopetalum comprises five species in eastern Australia and New Guinea. C. tetrapterum Mattf., described from New Guinea, is reduced in synonymy under C. succirubrum C. T. White, previously known only from northeastern Queensland. The genus Gillbeea comprises two species, one in north-eastern Queensland and one in New Guinea. The genus Aistopetalum comprises two species in New Guinea; one species is widespread in the northern parts of the island, the other is known only from the type collection. A. tetramerum Kan. et Hat. is reduced in synonymy under A. viticoides. The genus Calycomis is monotypic; its only species, C. australis (A. Cunn.) Hoogl. comb. nov. (Weinmannia australis A. Cunn.) is found in the Blue Mountains of New South Wales and is currently known as Acrophyllum verticillatum or A. venosum.

The green-eyed treefrogs (Litoria eucnemis species-group) are found throughout New Guinea and some of its offshore islands, and in two geographically separated regions in north-eastern Queensland, Australia. We examine the genetic relationships among populations of the complex from across its range and find that populations fall into two major lineages: 1) specimens referable to L. genimaculata from New Guinea and its offshore islands, and L. exophthalmia, and 2) samples referable to L. eucnemis from New Guinea and northern Cape York, Australia, and two lineages from the Wet Tropics of north-eastern Australia that are currently assigned to L. genimaculata. Based on our molecular genetic analyses, morphological assessment of new collections and re-examination of type material, we retain L. eucnemis as currently recognised for northern Cape York populations but resurrect the name L. serrata for the Wet Tropics populations. The degree of reproductive isolation between the two Wet Tropics lineages is being studied currently and so at this point we refer both to L. serrata. The degree of genetic variation observed in L. genimaculata across New Guinea locations and possible paraphyly with L. exophthalmia suggest the presence of additional undescribed species. Reexamination of type material and collection of new specimens, allow us to reassess the status of several other names currently synonymised with L. eucnemis and L. genimaculata. Our observations support the present synonymy of Hyla rhacophorus with L. eucnemis and we remove Nyctimystes loveridgei from the synonymy of L. genimaculata and place it in the synonymy of L. eucnemis.

Tectonic Reconstructions

Biostratigraphic data from exploration wells in Papua, West Papua of Indonesia, Papua New Guinea and Australia were reviewed, revised and updated using modern stratigraphic interpretations. Revised stratigraphic interpretations were combined with zircon U-Pb geochronologic data to produce new tectonic reconstructions of the Indonesian provinces of West Papua and Papua. Zircon U-Pb geochronologic data used in this study include new results from the Papuan Peninsula, combined with existing datasets from West Papua, Papua New Guinea, eastern Australia and New Caledonia. Supplementary geochronologic data were used to provide independent validation of the biostratigraphic data. Findings from a compilation of biostratigraphic and zircon age data provide a framework to produce new tectonic models for the origin of New Guinea’s terranes. Two hypotheses are presented to explain observations from the biostratigraphic and geochronologic data. The ‘Allochthonous Terrane’ Model suggests that many of the terranes are allochthonous in nature and may have been derived from eastern Australia. The ‘Extended Rift’ Model suggests that the New Guinea Terranes may have been separated from north-eastern Australia by an elongate rift system far more extensive than previously described. These new tectonic models are essential for our geological understanding of the regional and can be used to drive successful petroleum exploration in this frontier area.

Eighty-nine eucnemid genera occur in the region from South-east Asia to the south-west Pacific. The phylogenies of 84 of these were used together with the present-day distributions of the species to analyse the biogeographical history of the area. Fifty-seven genera shared a pattern coinciding with the traditional model of Laurasia–Gondwana break-up. Six genera showed a pattern contradicting the model. The remaining 21 genera neither supported nor refuted the model. Twenty-five genera were observed to include an Indomalesian clade younger than the South America–Australia connection. This biogeographical unit consisted of present-day South-east Asia and the Sunda islands, but did not include the Philippine Islands and Sulawesi. In addition to this Indomalesian clade, three separate clades involving northern Australia or New Guinea were observed, New Guinea–Australia, New Guinea–Philippines–Sulawesi and New Guinea–Fiji. The possible presence of four separate areas in the general region of New Guinea–north Australia as the result of the Cretaceous geological events is suggested. Three of these, in the area of present-day New Guinea, originally sharing sister-groups with the north-eastern Australian isolate, are regarded as the sources of the New Guinea–Indomalesia, New Guinea–Philippines and New Guinea–Fiji faunas after northward drifting of the Australian continent. During the Oligocene–Miocene these source areas were flooded and their original fauna lost. When the present-day New Guinea emerged, it was invaded from the north-eastern Australian region. This invasion created new New Guinea–Australia connections and brought in the sister-groups of the old New Guinea source areas as well. The eucnemids of Vanuatu, Samoa and Tonga are regarded as having originated in connection with dispersal from Fiji. The New Zealand fauna has strong, old connections with that of south-eastern Australia, but other complex connections are indicated. The Eocene Baltic Amber fauna agrees well with the results obtained from extant species. The species belonging to five fossil genera belong to Gondwanan groups that seem to have invaded the Holarctic via Central America. Four other fossil genera showing discordant patterns belong to the group of six genera exhibiting these aberrant patterns even today. The eucnemid fauna of the region is of Gondwanic origin. Only six Laurasian genera have invaded the area, all of them apparently quite recently.
