The genus Medicosma Hooker f., which has traditionally been considered to be monotypic and endemic to Australia, consists of 22 species. Six of these are endemic to eastern Australia, one is endemic to southern New Guinea and 15 are endemic to New Caledonia. The genus is described and its taxonomic history and relationships to other genera are discussed. The species are described, keyed and their relationships are outlined and discussed. Seventeen species are described as new, namely M. elliptica, M. obovata, M, glandulosa, M, diversifolia, M. articulata, M. parvifolia, M. obliqua, M. tahafeana, M. emarginata, M. verticillata, M. congests, M. latifolia, M. subsessilis, M. suberosa, M. petiolaris, M. exigua and M. gracilis, and new combinations are made for M. fareana (F. Mueller) T. Hartley, M. sessiliflora (C. T. White) T. Hartley, M. riparia (van Royen) T. Hartley and M. leratii (Guillaumin) T. Hartley.

The rain forest genus Sarcomelicope Engler consists of six species, five endemic to New Caledonia and one. with three subspecies, distributed from eastern Australia to Fiji. The genus is described and its taxonomic history and apparent ancestry are discussed. The species are keyed, described and their apparent relationships are outlined. Two species. S. glauca and S. dogniensis. are described as new, and new combinations are made for the names of four taxa, S. leiocarpa. S. simplicfolia, S. sirnplicfolia subsp. neo- scotica and S . Simplicifolia subsp. petiolaris. all of which were recently placed in the genus Bauerella Borzi (Rutaceae).

It is reported that Gaudichaud was correct in describing, under Brachycome Cass., three species, B. triloba, B. dentata and B. spathulata. Reference is made to the nomenclatural status of these species in accordance with the results of a revision of Brachycome by Davis (1948). De Candolle erred in transferring the species to Vittadinia A. Rich, for which the New Zealand V. australis is the type. Reasons are given for regarding V. triloba (Gaudich.) DC. as synonymous with V. australis var. dissecta Benth., and the variety is raised to specific rank. Included with V. australis and V. dissecta in Vittadinia s. str. (i.e. in Vittadinia subgenus Vittadinia) are V. cuneata DC. (a name which can be applied to a complex group of taxa widespread in southern and eastern Australia) and a further 17 species of which the following are new: V. cervicularis (with four varieties), V. constricta, V. condyloides, V. decora, V. eremaea, V. humerata, V. nullarborensis, V. pustulata, V. simulans and V. sulcata, while V. gracilis (J. D. Hook.) N. Burbidge and V. australasica (Turcz.) N. Burbidge are new combinations. V. scabra DC. and a group of taxa which have been referred to it or, incorrectly, to V. macrorhiza (DC.) A. Gray have been placed in a new subgenus of Vittadinia under the name Peripleura. Within this subgenus nine species are recognized: V. scabra DC., V, hispidula F. Muell. ex A. Gray (with two varieties), and the new species V. arida, V. bicolor, V. diffusa, V. obovata, V. sericea, V. spechtii (with two varieties) and V. virgata. With the exception of V. australis which is endemic to New Zealand and V. simulans, a New Caledonian species, all are endemic to Australia; however, V. hispidula has been reported for New Caledonia where it is deemed to be an alien and V. gracilis and possibly V. muelleri appear to have become naturalized in New Zealand. V. brachycomoides (F. Muell.) Benth. becomes the type of a new genus, Camptacra, with two species, both distributed in northern and north-eastern Australia. Eurybiopsis DC. is reinstated, with its single species, E. macrorhiza DC., found only in northern Australia.

The genera of microgastrine braconid wasps present in the Australasian region (defined as Australia, New Zealand, New Caledonia, New Guinea, Solomon Is, Fiji Is, Samoan Is, Cook Is, but not French Polynesia) are reviewed. An illustrated key to genera, comments on their taxonomy, and information on the distribution and host relationships of species are provided. Following examination of holotypes, the generic placement of all species recorded from the region is reassessed since a recent generic reclassification of the subfamily left most of the Australasian species incorrectly placed. Parapanteles Ashmead (N.T.), Fornicia Brullé (Qld) and Deuterixys Mason (Qld) are recorded from Australasia for the first time, while Buluka De Seager, Parenion Nixon, Snellenius Westwood and Wilkinsonellus Mason, previously known from Australasia, are recorded from mainland Australia for the first time. The genus Austrocotesia is described as new [with A. exigua, sp. nov. (Papua New Guinea) as the type species], along with the following 14 species: Austrocotesia delicata, sp. nov. (Papua New Guinea, Qld), A. paradoxa, sp. nov. (Papua New Guinea), Buluka collessi, sp. nov. (Qld), Deuterixys anica, sp. nov. (Vic., N.S. W., Qld), Fornicia commoni, sp. nov. (Qld), Glyptapanteles deliasa, sp. nov. (S.A.), Microgaster nixoni, sp. nov. (Tas., N.S.W.), Parapanteles masoni, sp. nov. (N.T.), Parenion beelaronga, sp. nov. (Qld), P. bootha, sp. nov. (Qld), Sathon albicoxa, sp. nov. (Tas., Vic., N.S.W.), S. naryciae, sp. nov. (Vic.), Wilkinsonellus amplus, sp. nov. (Qld, N.T.) and W. tomi, sp. nov. (Papua New Guinea, New Britain, Qld). Glyptapanteles guyanensis (Cameron), comb. nov. is excluded from the Australasian fauna; the name Glyptapanteles fullawayi, nom. nov. (Samoa) is proposed for Apanteles opercuiinae var. polita Fullaway; lectotypes are designated for Cotesia deliadis (Bingham), comb. nov. (Qld), C. philoeampa (Cameron), comb. nov. (N.S.W) and C. rufiventris (Bingham), comb. nov. (Qld); Glyptapanteles operculinae (Fullaway), comb. nov. (Samoa), Microgaster kuchingensis Wilkinson (Papua New Guinea) and Sathon moratus (Wilkinson), comb. nov. (Vic., S.A., W.A.) are redescribed; and 41 additional new combinations are proposed.

<p>Northern Zealandia lies between Australia, New Zealandia, and New Caledonia. It has an area of 3,000,000 km2 and is made up of bathymetric rises and troughs with typical water depths of 1000 to 4000 m. I use 39,309 line km of seismic-reflection profiles tied to recent International Ocean Discovery Program (IODP) drilling and three boreholes near the coast of New Zealand to investigate stratigraphic architecture and assess the petroleum prospectivity of northern Zealandia.  Sparse sampling requires that stratigraphic and petroleum prospectivity inferences are drawn from better-known basins in New Zealand, Australia, New Caledonia, TimorLeste and Papua New Guinea. Five existing seismic-stratigraphic units are reviewed. Zealandia Seismic Unit U3 is sampled near New Zealand and may contain Jurassic Muhiriku Group coals. Elsewhere, Seismic Unit 3 may have oil-prone equivalents of the Jurassic Walloon Coal Measure in eastern Australia; or may contain Triassic-Jurassic marine source rocks, as found in offshore Bonaparte Basin, onshore Timor-Leste, and the Papuan Basin in Papua New Guinea. Seismic Unit U2b (Mid-Cretaceous) is syn-rift and may contain coal measures, as found in Taranaki-Aotea Basin and New Caledonia. Seismic Unit U2a (Late Cretaceous to Eocene) contains coaly source rocks in the southeastern part of the study area, and may also contain marine equivalent carbonaceous mudstone, as found at Site IODP U1509. Unit U2a is transgressive, with coaly source rocks and reservoir sandstones near its base, and clay, marl and chalk above that provides a regional seal. Seismic Unit U1b (Eocene-Oligocene) is mass-transport complexes and basin floor fans related to a brief phase of convergent deformation that created folds in the southern part of the study area and regionally uplifted ridges to create new sediment source areas. Basin floor fans may contain reservoir rock and Eocene folding created structural traps. Seismic Unit U1a is Oligocene and Neogene chalk, calcareous ooze, and marl that represents overburden. Mass accumulation rates (MAR) and climatic temperatures were high in the late Miocene and early Pliocene, resulting in peak thermal maturity and hydrocarbon expulsion at ~ 3 Ma.  Approximately one-fifth of the region has adequate source rock maturity for petroleum expulsion at the base of Seismic Unit U2: Fairway Basin (FWAY), southern New Caledonia Trough (NCTS) and Reinga Basin (REIN). Plays may exist in either Seismic Unit U3 or U2, with many plausible reservoir-seal combinations, and several possible trapping mechanisms: unconformities, normal faults, folds, or stratigraphic pinch-out. The rest of the region could be prospective, but requires a source rock to exist within Seismic Unit U3, which is mostly unsampled and remains poorly understood.</p>

The validity of the generic concept of Babingtonia Lindl. adopted by Bean (1997a) is tested in the light of molecular and morphological data. Molecular analyses support recognition of segregate genera, none of which is closely related to the type of the genus, Babingtonia camphorosmae, a western Australian species. Two genera, Sannantha and Kardomia, are described as new and a third genus, Harmogia, resurrected from synonymy; new combinations are provided in the new genera. A fourth group, consisting of ‘Babingtonia’ behrii and its allies, appears distinct but, as a predominantly southern group, with numerous western Australian representatives, is not treated further.

Neoaratus Ricardo is redefined and considered as monotypic. Six new genera, Abrophila, Colepia, Dolopus, Mauropteron, Reburrus and Zosteria, are erected to accommodate 19 species previously placed in Neoaratus as well as 39 new species described below. The following are proposed as new synonyms: Asilus grandis Macquart, 1848 = A. rufiventris Macquart, 1838; Asilus leon Walker, 1849 = A. rubrithorax Macquart, 1838; Mochtherus lautus van der Wulp, 1872 = A. biligata Walker, 1864; Asilus ferrugineiventris Macquart, 1850 = A. fulvipubescens Macquart, 1850. Asilus grandis Macquart is removed from synonymy with Neoaratus hercules (Wiedemann) and proposed as a synonym of A. rufiventris Macquart, 1838. Abrophila whitei is proposed as a replacement name for the preoccupied Asilus aureus White, 1918. The following are new combinations: Colepia abludo (Daniels, 1983), C. ingloria (Macleay, 1826), C. malleola (Walker, 1849), C. rufiventris (Macquart, 1838); Dolopus genitalis (Hardy, 1920), D. rubrithorax (Macquart, 1838); Mauropteron pelago (Walker, 1849); Reburrus bancrofti (Hardy, 1935), R. kochi (de Meijere, 1913), R. macquarti (Bigot, 1860), R. wieneckii (van der Wulp, 1872); Zosteria alcetas (Walker, 1849), Z. biligata (Walker, 1864); Z. fulvipubescens (Macquart, 1850), Z. iflingworthi (Hardy, 1922), Z. murina (Macquart, 1838), Z. rosevillensis (Hardy, 1935), Z. sydneensis (Macquart, 1838). The following new species are described: Colepia chrysochaites, C. comatacauda, C. compernis, C. cultripes, C. flavifacies, C. horrida, C. ignicolor, C. lanata, C. naevia, C. novaeguineae; Dolopus mirus, D. silvestris, D. simulans; Mauropteron farinum; Reburrus aquilonius, R. caledonicae, R. peninsularis; Zosteria affinis, Z. alpina, Z. caesariata, Z. calignea, Z, claudiana, Z. clausum, Z. clivosa, Z. eastwoodi, Z. hispida, Z. lineata, Z. longiceps, Z. montana, Z, nigrifemorata, Z. novazealandica, Z. punicea, Z. queenslandi, Z. rubens, Z. ruspata, Z. suda, Z. varia and Z. venato. All seven genera occur in Australia. Species of three genera, Colepia, Reburrus and Zosteria, also occur elsewhere, as follows: Timor (R. wieneckii], New Guinea (C. novaeguineae, R. kocki, Z. biligata and Z. illingworthi), New Caledonia and New Hebrides (R. caledonicae and R. macquarti], and New Zealand (Z. novazealandica). Z. illingworthi is common to Australia and New Guinea. The female reproductive system and the components of the male terminalia are illustrated and briefly described for most species. Pupal exuviae of C. ingloria, C. malleola, C, rufiventris, N. hercules, Z. fulvipubescens and Z. sydneensis are illustrated and/or described. Keys to the genera of Australian Asilini and the species of the new genera are given. Lectotypes are designated for Antipalus wieneckii, Asilus ferrugineiventris, A. leon, A. murinus, A. pelago, A. rufiventris, Neoaratus bancrofti and N. rosevillensis. Asilus regius Jaennicke and Asilus tasmaniae Macquart, formerly considered as species of Neoaratus, are not treated because their status is uncertain.

The Australian species of Alysiini are revised. Fourteen genera are treated, with eight of these recorded from Australia for the first time. Two of the genera, one from eastern Australia and one from New Guinea, are described as new. Two new subgenera are described, Idiasta Foerster (Apiasta, subgen. nov.) and Leptolarthra Fischer (Cratocarpa, subgen. nov.). Forty-nine species are described, 43 of them new: one in Aphaereta Foerster; eight in Aspilota Foerster; six in Cratospila Foerster; 13 in Dinotrema Foerster; one in Heleomyzophaga, gen. nov.; one in Heratemis Walker; one in Hovhoa, gen. nov.; four in Idiasta; three in Leptolarthra; three in Orthostigma Ratzeburg; one in Phaenocarpa Foerster; and one in Tanycarpa Foerster. Keys are presented to all genera of Alysiinae known from Australia as well as the Australian species of Asobara, Aspilota, Cratospila, Dinotrema and Orthostigma. Additionally, the world genera are reviewed and their relationships discussed to provide a context for an assessment of the Australian fauna. The status of 80 available genus-group names is discussed. The following nomenclatural changes are proposed: Neorthostigma Belokobylskij and Patriaspilota Fischer are treated as subgenera of Orthostigma; Acrobela Foerster as a synonym of Tanycarpa; Idiolexis Foerster as a synonym of Phaenocarpa; Eudinostigma Tobias as a synonym of Dinotrema; and Leptotrema van Achterberg as a subgenus of Dinotrema. The following new combinations are in addition to those associated with the above nomenclatural changes: Aspilota magnareata (Fischer); Dinotrema hardyi (Fischer); Dinotrema parvimaxillatum (Fischer); Dinotrema rotatum (Fischer); Dinotrema schoenmanni (Fischer); Leptolarthra cubiceps (Bischoff); and Orthostigma orthostigmoides (Fischer). Host records are included for two of the newly described species. Heleomyzophaga collessi, gen. nov. et sp. nov. was reared from a heleomyzid fly and Dinotrema monstrosum, sp. nov. was reared from a platypezid fly. A third species, Idiasta minor, sp. nov., was collected from pitfall traps baited with carrion.

The ant genus Leptomyrmex contains 41 named taxa which are limited to eastern Australia, New Guinea and New Caledonia. While most species are large and distinctive, a few species are much smaller and have only recently been recognised as belonging to this genus. These six species, informally called micro-Leptomyrmex, are restricted to rainforests and wet sclerophyll forests in two relatively small regions of eastern Australia. All are described here for the first time and include L. aitchisoni n. sp., L. burwelli n. sp., L. dolichoscapus n. sp., L. garretti n. sp., L. pilosus n. sp. and L. ramorniensis n. sp.
