SummaryThe ultramafic—mafic complex at North Cape lies in a Mesozoic—Lower Tertiary tectonic belt linking New Zealand with New Caledonia and Papua New Guinea. The complex is faulted against Cretaceous submarine tholeiites and contains (1) serpentinized harzburgite and lherzolite of probable cumulus origin (and intruded by more Fe-rich wehrlitic veins and dykes), overlain by (2) layered olivine- and orthopyroxene-gabbro subvolcanic cumulates which are themselves host for (3) a sheeted dyke swarm of mainly quartz-diorite composition. It is suggested that the complex was emplaced with the Cretaceous volcanics by obduction of Mesozoic oceanic crust during the Lower Tertiary.

<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>

Manota ctenophora Matile (New Caledonia), M. maorica Edwards (New Zealand) and M. taedia Matile (New Caledonia) are redescribed. Manota hamulata Colless, previously known from Palau, is redescribed and recorded from Papua New Guinea. Manota pacifica Edwards from Samoa is discussed and compared with the other species of the region. A key to the Melanesian and Oceanian species of Manota is given.

New Genera

Stiletto-flies (Diptera: Therevidae) are highly diverse and species-rich in Australia and New Zealand, yet relatively few species have been recorded from neighbouring Papua New Guinea, Indonesia and throughout the remainder of Oceania. Indeed, in New Caledonia only a single species of the widely distributed Australasian genus Anabarhynchus Macquart (Therevinae) is previously known. Herein we describe two new agapophytine genera (i.e., Jeanchazeauiagen. nov., Calophytusgen. nov.), together comprising nine charismatic new species; this represents a first record of the subfamily from New Caledonia. The new genera and species are described and figured.

First Record

Xiphydriid woodwasps have been very rarely collected in Australasia although they are widely distributed in the region. Species have been described from the Aru, Ambon and Buru Islands, Indonesia, eastern mainland Australia, Papua New Guinea, and New Zealand. Here Rhysacephala novacaledonica Jennings & Austin, sp. nov., is described, which is the first record of a xiphydriid woodwasp from New Caledonia. In addition, a key to genera for the region is presented, along with a discussion of the biology and distribution of the group in Australasia.
