Australasian Region

Five species of the nephilid genus Nephila Leach are found in the Australasian region, which for the purposes of this study was defined as Australia and its dependencies (including Lord Howe I., Norfolk I., Christmas I., Cocos (Keeling) Is), New Guinea (including Papua New Guinea and the Indonesian province of West Papua), Solomon Is, Vanuatu, New Caledonia, Fiji, Tonga, Niue, New Zealand and other parts of the south-west Pacific region. All species are redescribed and illustrated. Nephila pilipes (Fabricius) occurs in the closed forests of eastern and northern Australia, New Guinea, Solomon Is and Vanuatu (through to South-East Asia); N. plumipes (Latreille) is found in Australia (including Lord Howe I. and Norfolk I.), New Guinea, Vanuatu, Solomon Is and New Caledonia; N. tetragnathoides (Walckenaer) inhabits Fiji, Tonga and Niue; N. antipodiana (Walckenaer) occurs in northern Australia (as well as Christmas I.), New Guinea and Solomon Is (through to South-East Asia); and N. edulis (Labillardière) is found in Australia (including Cocos (Keeling) Is), New Guinea, New Zealand and New Caledonia. Epeira (Nephila) walckenaeri Doleschall, E. (N.) hasseltii Doleschall, N. maculata var. annulipes Thorell, N. maculata jalorensis Simon, N. maculata var. novae-guineae Strand, N. pictithorax Kulczyński, N. maculata var. flavornata Merian, N. pictithorax Kulczyński, N. maculata var. flavornata Merian, N. maculata piscatorum de Vis, and N. (N.) maculata var. lauterbachi Dahl are proposed as new synonyms of N. pilipes. Nephila imperialis var. novaemecklenburgiae Strand, N. ambigua Kulczyński, N. sarasinorum Merian and N. celebesiana Strand are proposed as new synonyms of N. antipodiana. Meta aerea Hogg, N. meridionalis Hogg, N. adelaidensis Hogg and N. meridionalis hermitis Hogg are proposed as new synonyms of N. edulis. Nephila picta Rainbow is removed from the synonymy of N. plumipes and treated as a synonym of N. edulis, and N. nigritarsis insulicola Pocock is removed from the synonymy of N. plumipes and treated as a synonym of N. antipodiana. Allozyme data demonstrate that N. pilipes is distinct at the 80% FD level from N. edulis, N. plumipes and N. tetragnathoides. Nephila plumipes and N. tetragnathoides, deemed to represent sister-taxa owing to the shared presence of a triangular protrusion of the male pedipalpal conductor, were found to differ at 15% FD in the genetic study. No genetic differentiation was found between 10 populations of N. edulis sampled across mainland Australia. Species of the genus Nephila have been extensively used in ecological and behavioural studies, and the biology of Nephila species in the Australasian region is extensively reviewed and compared with studies on Nephila species from other regions of the world.

Solenostoma truncatum (Nees 1830: 29) R.M. Schust. ex Váňa & D.G.Long (2009: 509) is widely distributed and the commonest Solenostoma-species in south-east Asia, reaching from Himalayas, India and Srí Lanka to China, Japan, Micronesia, Samoa, New Guinea and northern Australia (Queensland). The species is very variable: its leaf form varies from subquadrate-rotund, ovate, ovate-ligulate to rarely ligulate, the cell texture is also relatively variable, but the marginal leaf-cells are mostly ± equally thickened in 1–2 or more rows, and the cuticle is usually at least minutely verrucose, rarely nearly smooth. Perianth is shortly to longly exserted, fusiform or ovate, perianth mouth is contracted or wide, crenulate, sometimes with ciliate marginal cells. Many  synonyms were published for S. truncatum.

Australian Species

Acacia sensu stricto is found predominantly in Australia; however, there are 18 phyllodinous taxa that occur naturally outside Australia, north from New Guinea to Indonesia, Taiwan, the Philippines, south-western Pacific (New Caledonia to Samoa), northern Pacific (Hawaii) and Indian Ocean (Mascarene Islands). Our aim was to determine the phylogenetic position of these species within Acacia, to infer their biogeographic history. To an existing molecular dataset of 109 taxa of Acacia, we added 51 new accessions sequenced for the ITS and ETS regions of nuclear rDNA, including samples from 15 extra-Australian taxa. Data were analysed using both maximum parsimony and Bayesian methods. The phylogenetic positions of the extra-Australian taxa sampled revealed four geographic connections. Connection A, i.e. northern Australia?South-east Asia?south-western Pacific, is shown by an early diverging clade in section Plurinerves, which relates A. confusa from Taiwan and the Philippines (possibly Fiji) to A. simplex from Fiji and Samoa. That clade is related to A. simsii from southern New Guinea and northern Australia and other northern Australian species. Two related clades in section Juliflorae show a repeated connection (B), i.e. northern Australia?southern New Guinea?south-western Pacific. One of these is the ?A. auriculiformis clade', which includes A. spirorbis subsp. spirorbis from New Caledonia and the Loyalty Islands as sister to the Queensland species A. auriculiformis; related taxa include A. mangium, A. leptocarpa and A. spirorbis subsp. solandri. The ?A. aulacocarpa clade' includes A. aulacocarpa, A. peregrinalis endemic to New Guinea, A. crassicarpa from New Guinea and Australia, and other Australian species. Acacia spirorbis (syn. A. solandri subsp. kajewskii) from Vanuatu (Melanesia) is related to these two clades but its exact position is equivocal. The third biogeographic connection (C) is Australia?Timor?Flores, represented independently by the widespread taxon A. oraria (section Plurinerves) found on Flores and Timor and in north-eastern Queensland, and the Wetar island endemic A. wetarensis (Juliflorae). The fourth biogeographic connection (D), i.e. Hawaii?Mascarene?eastern Australia, reveals an extreme disjunct distribution, consisting of the Hawaiian koa (A. koa, A. koaia and A. kaoaiensis), sister to the Mascarene (R�union Island) species A. heterophylla; this clade is sister to the eastern Australian A. melanoxylon and A. implexa (all section Plurinerves), and sequence divergence between taxa is very low. Historical range expansion of acacias is inferred to have occurred several times from an Australian?southern New Guinean source. Dispersal would have been possible as the Australian land mass approached South-east Asia, and during times when sea levels were low, from the Late Miocene or Early Pliocene. The close genetic relationship of species separated by vast distances, from the Indian Ocean to the Pacific, is best explained by dispersal by Austronesians, early Homo sapiens migrants from Asia.

Dry Conditions

Fossil pollen and spores preserved in drillcore from both the upper South Alligator River (SARV) in the Kakadu National Park, Northern Territory and the North-West Shelf, Western Australia provide the first record of plants and plant communities occupying the coast and adjacent hinterland in north-west Australia during the Paleogene 66 to 23million years ago. The palynologically-dominant woody taxon is Casuarinaceae, a family now comprising four genera of evergreen scleromorphic shrubs and trees native to Australia, New Guinea, South-east Asia and Pacific Islands. Rare taxa include genera now mostly restricted to temperate rainforest in New Guinea, New Caledonia, New Zealand, South-East Asia and/or Tasmania, e.g. Dacrydium, Phyllocladus and the Nothofagus subgenera Brassospora and Fuscospora. These appear to have existed in moist gorges on the Arnhem Land Plateau, Kakadu National Park. No evidence for Laurasian rainforest elements was found. The few taxa that have modern tropical affinities occur in Eocene or older sediments in Australia, e.g. Lygodium, Anacolosa, Elaeagnus, Malpighiaceae and Strasburgeriaceae. We conclude the wind-pollinated Oligocene to possibly Early Miocene vegetation in the upper SARV was Casuarinaceae sclerophyll forest or woodland growing under seasonally dry conditions and related to modern Allocasuarina/Casuarina formations. There are, however, strong floristic links to coastal communities growing under warm to hot, and seasonally to uniformly wet climates in north-west Australia during the Paleocene-Eocene.

The scorpion-tailed orb-weaving spiders in the genus Arachnura Vinson, 1863 (Araneidae Clerck, 1757) are revised for Australia and New Zealand. Arachnura higginsii (L. Koch, 1872) only occurs in Australia and A. feredayi (L. Koch, 1872) only in New Zealand. A single female collected in south-eastern Queensland (Australia) is here tentatively identified as A. melanura Simon, 1867, but it is doubtful that this species has established in Australia. Two juveniles from northern Queensland do not conform to the diagnoses of any of the above species and are illustrated pending a more thorough revision of the genus in South-East Asia and the Pacific region. An unidentified female from Westport (New Zealand) does not conform to the diagnoses of A. feredayi and A. higginsii, but is not described due to its poor preservation status. Arachnura caudatella Roewer, 1942 (replacement name for Epeira caudata Bradley, 1876), originally described from Hall Sound (Papua New Guinea) and repeatedly catalogued for Australia, is considered a nomen dubium.

Occurrence Of Species

The southern segregates of Veronica (Hebe, Parahebe, Chionohebe, Dementia, and Detzneria) form a monophyletic assemblage of c. 144 species found in New Guinea, Australia, New Zealand, Rapa, and South America. Most of the species occur in New Zealand, where Hebe is the largest genus and a characteristic member of many vegetation types. Cladistic analysis of the Hebe complex, based on 45 characters and 22 terminal taxa, indicates that: (1) Hebe is monophyletic if Hebe 'Paniculatae' is excluded and H. formosa is included; (2) Parahebe is paraphyletic; (3) Chionohebe is monophyletic, but is part of a larger clade which includes alpine Parahebe and possibly the monotypic Detzneria; (4) Hebe 'Paniculatae', Derwentia, and New Guinea Parahebe are monophyletic basal groups in the complex. According to this study, recognition of monophyletic genera would require six genera in the complex, supporting the recognition of Derwentia and separation of Hebe 'Paniculatae' from Hebe. Leonohebe Heads is considered polyphyletic and is not accepted; new combinations are provided for two species of Leonohebe with no name at species rank in Hebe. Competing biogeographic hypotheses have implied (1) a Gondwanan origin, or (2) migration from South-east Asia via New Guinea. An origin in Australasia from Asian ancestors best explains the topology of the basal parts of the cladogram, but at least seven dispersal events from New Zealand are postulated to explain the occurrence of species of Hebe in South America and Rapa and Parahebe, Hebe, and Chionohebe in Australia. An hypothesis which did not allow dispersal would require that nearly all the evolution in the complex occurred before the Tertiary, and hardly any since.

A New Species

The Australian pyralid stem borers of Gramineae, Cyperaceae, and Juncaceae, previously assigned to Schoenobius Duponchel and Scirpophaga Treitschke, are here referred to six genera. Scirpophaga Treit. - Eight species are recognized: S. chrysorrhoa Zeller, S. phaedima, sp. nov., S. limnochares, sp. nov., S. xantharrenes, sp. nov., S. imparella (Meyrick), S. helodes, sp. nov., S. percna, sp. nov., and S. ochroleuca (Meyrick). Though some of these bear a superficial resemblance to the true rice stem borers, the genus includes species whose larvae attack sedges (Cyperaceae). Helonastes, gen. nov. - The genus is based on a new species, H. acentrus, associated with Eleocharis (Cyperaceae) in central Queensland. Niphadoses, gen. nov.-The genus is erected to include three new Australian species, N. palleucus, which is associated with cultivated rice in north-western Australia, N. elachia, and N. hoplites, together with N. chionotus (Meyrick) from New Guinea and N. gilbiverbis (Zeller) from India. Catagela Walker. - A new species, C. adoceta, from northern Australia, is described. Tryporyza gen. nov. - The genus is established to receive the two important stem-borer pests of cultivated rice, Tipanaea innotata Walker from south-east Asia and northern Australia and Chilo incertulas Walker from south-east Asia, previously referred to Scirpophaga and Schoenobius respectively. Also included are Scirpophaga butyrota Meyrick from New Guinea and Schoenobius melanostigmus Turner from the Cape York Peninsula. It is suggested that T. innotata already occurred in northern Australia before European settlement. Tipanaea Walker. - The genus is restricted to the single Australian species, T. patulella Walker, associated with Juncaceae. Genitalic and other structures used to distinguish these genera are discussed. The genitalia of both sexes and the wings of the Australian species are figured, and keys to the genera and species are included.

Each of the 14 genera now referred to the subfamily Diplodactylinae (Naultinus, Hoplodactylus, Heteropholis, Bavayia, Rhacodactylus, Eurydactylodes, Pseudothecadactylus, Carphodactylus, Phyllurus, Nephrurus, Oedura, Diplodactylus, Rhynchoedura, and Crenadactylus) is characterized on the basis of its internal and external morphology. The type species, referred species, and distribution are given for each genus. The Diplodactylinae are divided into two tribes primarily on the basis of differences in the arrangement and number of preanal pores and the size and shape of the nasal process of the premaxilla. The Carphodactylini includes Naultinus, Hoplodactylus, Heteropholis, Bavayia, Rhacodactylus, Eurydactylodes, Carphodactylus, Pseudothecadactylus, Phyllurus, and Nephrurus. The Diplodactylini includes Diplodactylus, Oedura, Rhynchoedura, and Crenadactylus. The Carphodactylini appear to be more primitive than the Diplodactylini. Carphodactylus may be close to the ancestral stock of the subfamily. Phyllurus and Nephrurus seem to be closely related to Carphodactylus. Pseudothecadactylus is considered to be closely related to the New Caledonia-Loyalty Islands radiation, which consists of Eurydactylodes and Rhacodactylus, and probably Bavayia. The New Zealand genera Hoplodactylus, Heteropholis, and Naultinus seem to form a natural group which is related to the New Caledonian genera. Crenadactylus is probably only distantly related to the other genera of the Diplodactylini. Rhynchoedura seems to be related to the stenodactylus group of Diplodactylus, while Oedura shows an affinity to the strophurus group of that genus. Geographically, the Diplodactylinae is restricted to the Australian Region (Australia, New Caledonia, Loyalty Islands, and New Zealand). The ancestral stock of the subfamily probably originated in south-east Asia and dispersed toward Australia by way of the Indo-Australian Archipelago during the upper Cretaceous. It is postulated that the subfamily reached Australia (and continental New Guinea) by Palaeocene- Eocene time.

Widespread Species

A morphometric study was undertaken to survey taxa in the genus Euchiton Cass., distributed across Australia, New Zealand and South-east Asia. Phenetic analyses of herbarium specimens showed several taxa to be well delimited, including E. brassii (Mattf.) Anderb., E. breviscapus (Mattf.) Anderb., E. lateralis (C.J.Webb) Breitw. & J.M.Ward, E. limosus (D.G.Drury) Holub, E. litticola A.M.Buchanan, E. traversii (Hook.f.) Holub and E. umbricola (J.H.Willis) Anderb. However, the analyses showed that the remainder of Euchiton taxa are not yet satisfactorily resolved taxonomically. The distributions of E. involucratus (G.Forst.) Holub and E. sphaericus (Willd.) Holub were elucidated, although these widespread species would benefit from more research. Further research is necessary into species delimitation between E. paludosus (Petrie) Holub and E. polylepis (D.G.Drury) Breitw. & J.M.Ward and within the E. japonicus complex, including E. audax (D.G.Drury) Holub, E. collinus Cass., E. delicatus (D.G.Drury) Holub, E. ensifer (D.G.Drury) Holub, E. japonicus (Thunb.) Holub and E. ruahinicus (D.G.Drury) Breitw. & J.M.Ward. Recognition of a proposed taxon E. ‘gracilis’ was not supported and description at this point is not recommended. The New Zealand material of E. audax, E. delicatus and E. ensifer was shown to differ from the Australian material in the micromorphology of the cypselae. Euchiton collinus is considered a synonym of E. japonicus, which also includes the Australian material attributed to E. audax, E. delicatus and E. ensifer. The presence of E. limosus in Australia was confirmed, with it differing from E. involucratus in having glabrous cypselae with paired papillae in both Australian and New Zealand material. Generic boundaries of Euchiton are problematic. The generic placement of Gnaphalium clemensiae Mattf. and E. umbricola remains unresolved. Insufficient data were available to make taxonomic conclusions regarding the generic placement of G. chiliastrum (Mattf.) P.Royen and G. heleios P.Royen from New Guinea.
