Raoul Island is the largest and northernmost of the main Kermadec Islands, 900 km (560 mi) south south-west of 'Ata Island of Tonga and 1,100 km (680 mi) north north-east of New Zealand's North Island. It has been the source of vigorous volcanic activity during the past several thousand years that was dominated by dacitic explosive eruptions.
Macropathus is a genus of cave wētā in the family Rhaphidophoridae, endemic to New Zealand.
Sigaus australis is the most common alpine grasshopper found in New Zealand. It can be found in the southern half of the South Island above the tree line. Sigaus australis was described in 1897 by Frederick Hutton. Like all of New Zealand sub-alpine and alpine grasshoppers S. australis has a 2 or 3 years life cycle. Individuals can survive the cold by freezing solid at any life stage, at any time of the year. Sigaus australis adults are relatively large grasshoppers. The genus Sigaus is endemic to New Zealand.
Thomas Broun was a Scottish-born soldier, farmer, teacher and entomologist, who spent much of his career in New Zealand. He is known for his study of the beetles (Coleoptera) of New Zealand.
Anagotus stephenensis, commonly known as the ngaio weevil, is a large flightless weevil that is only found on Stephens Island in New Zealand. The ngaio weevil was discovered in 1916 by A.C. O'Connor on Stephens Island. Thomas Broun described it in 1921 as Phaeophanus oconnori after its collector. The weevils were observed at the time to be 'feeding on tall fescue and the leaves of trees'.
Peristoreus fulvus is a species of true weevil. It is endemic to New Zealand. It is associated with plants of the genus Muehlenbeckia.
Didymus metrosideri is an endemic weevil from the Kermadec Islands in New Zealand. This species was discovered by W. L. Wallace during the 1908 Kermedec Islands expedition.
Amychus granulatus, commonly known as the Cook Strait click beetle, is a large flightless click beetle in the family Elateridae.
Merlin Owen Pasco was a New Zealand entomologist. Pasco discovered several species of moth previously unknown to science and collected numerous specimens.
Geodorcus ithaginis, the Mokohinau stag beetle, is a large flightless species of stag beetle in the family Lucanidae. It was described by Thomas Broun in 1893 after being discovered in the Mokohinau Islands by Andreas Stewart Sandager, a lighthouse keeper on the islands. The species survives only on the small unnamed island "Stack H", in a patch of vegetation the size of a living room, and is in extreme danger of extinction.
Geodorcus philpotti is a large flightless species of stag beetle in the family Lucanidae. It was named by Major Thomas Broun after Mr A. Philpott, who discovered it at Hump Ridge near Invercargill. It is endemic to New Zealand.
The Kermadec spiny dogfish is a dogfish described in 2007. It is a member of the family Squalidae, found off the Kermadec Islands. The length of the longest specimen measured is 68.1 cm (26.8 in).
Lyperobius hudsoni is a flightless weevil found in alpine areas of Central Otago and Otago Lakes in the South Island of New Zealand.
Amychus manawatawhi, commonly known as the Three Kings click beetle, is a large flightless click beetle in the family Elateridae, found only on the Three Kings Islands of New Zealand.
Hoherius meinertzhageni, the ribbonwood fungus weevil, is an endemic New Zealand beetle that has been recorded feeding on the ribbonwood species Plagianthus regius and Plagianthus divaricatus and the mountain lacebark, Hoheria glabrata.
Mecodema scitulum is a species of endemic New Zealand flightless beetle in the family Carabidae. It was first described by Thomas Broun, in 1984, from a single specimen that he received from the Edwin Mitchelson. This species then became a junior synonym of Mecodema spiniferum after Everard B. Britton completed his revision of the New Zealand Broscini in 1949. Like Broun, Britton based this synonymy on the only specimen available, the holotype, because of the confusion surrounding the type locality where M. scitulum was collected from. However, D.S. Seldon and T.R. Buckley (2019) reinstated the species M. scitulum based on the morphological comparisons of 30+ specimens with the holotype and molecular analyses.
Polychrosis meliscia is a species of moth of the family Tortricidae. It is found in New Zealand at the Kermadec Islands.
Dr Aola Mary Richards was a New Zealand entomologist specialising in the study of New Zealand and Australian cave crickets, or wētā (Rhaphidophoridae), and Australian ladybird beetles (Coccinellidae). She was the first New Zealand woman to gain a PhD in biology.
Tyrannochthonius kermadecensis is a species of pseudoscorpion in the Chthoniidae family. It was described in 1976 by Austrian arachnologist Max Beier.
Prodontria longitarsis is a species of flightless beetle in the family Scarabaeidae. This species was first described by Broun in 1909 as Odontria longitarsis. The holotype specimen was collected by George Hudson during the Sub-Antarctic Islands Scientific Expedition and is held at Te Papa.
