FIGURE 2. Schematic representation of published mtDNA COI sequence variation within species lineages of endemic Aotearoa New Zealand Acrididae in the alpine radiation (Supplementary Table S1 for data details). Recorded locations of each taxon are coloured as shown in the phylogeny (left). Triangles on maps indicate two rare, localised species that are recognised by morphology, but are phylogenetically nested within other more widespread lineages (with corresponding colour). The sampling locations of specimens used in the current study are indicated on the maps with their unique identifiers (see Table 2).

Figure 1B. Māwhitiwhiti Aotearoa are diverse in form and ecology. An adult male Sigaus minutus is shown on top of an adult female Sigaus villosus to allow size comparison of smallest and largest species within this radiation. See Table 1.

Bathymetric elevation models of the Southern Hikurangi Subduction Margin, New Zealand

Multibeam bathymetric data compiled by the National Institute of Water and Atmospheric Research (NIWA), New Zealand, are presented for the southern Hikurangi Subduction Margin, New Zealand. These datasets cover the eastern continental slope of southern Wairarapa, North Island, and Marlborough, South Island, the adjacent northwestern slope of the Chatham Rise, and the southern Hikurangi Trough. The data were collected for scientific research purposes, primarily for the study of continental margin active tectonics and sedimentary systems associated with NIWA SSIF Programme Marine Geological Processes (and its predecessors).Prominent features of the data are:<ol><li>the numerous submarine canyons and gully systems that incise the continental slopes and deliver sediment from the shelf to the southern Hikurangi Trough. These include the Kaīkoura, Hurunui, Pegasus, Okains, and Pūkākī canyons of NE South Island, the Cook Strait Canyon and its numerous tributaries, and the Opouawe, Pahaua, Honeycomb, and Madden canyon systems of SE North Island;</li><li>Elongate bathymetric ridges along the Marlborough and Wairarapa continental slopes that result from seafloor uplift associated with tectonic thrust faults propagating beneath them;</li><li>The flat basin floor of the 2500-3000 m deep Hikurangi Trough, incised by the meandering Hikurangi Channel; and</li><li>Mernoo Bank on the crest of the Chatham Rise.</li></ol>Bathymetric DataTwo separate bathymetric data sets are provided, covering northern and southern regions. The northern dataset is presented at a 50 m grid resolution, and the southern at 25 m grid resolution. Both datasets are compilations of available multibeam bathymetric data collected on multiple voyages. Primarily, the bathymetric data was collected by NIWA on the RV Tangaroa using Kongsberg 30 kHz (EM300 and EM302) multibeam echo sounders, with some additional data collected by German and US vessels using 12 kHz multibeam echo sounders.List of data sets<ol><li>32-bit float GeoTIFF grid of offshore Marlborough bathymetry, New Zealand, at 25 m cell size.
