ABSTRACT Taxonomy lies at the heart of species conservation, yet many large New Zealand orthopterans remain undescribed. Among New Zealand’s anostostomatid wētā, Hemiandrus (ground wētā) is the most speciose genus but also the most poorly characterised and thus most in need of taxonomic and ecological work. Here we redescribe H. maculifrons and describe two new species of ground wētā previously encompassed by the specific name Hemiandrus maculifrons: Hemiandrus luna sp. nov. and H. brucei sp… Expand
Ecology and systematics of the wine wētā and allied species, with description of four new Hemiandrus species
TLDR
It is demonstrated that this wētā at unusually high density in some vineyards in the Awatere valley is also found in North Island forests (Hemiandrus bilobatus) and is described four new species which belong to the same ground w «tā clade as the wine wēTā. Expand
First detection of Wolbachia in the New Zealand biota
TLDR
These represent the first described instances of Wolbachia in the New Zealand native fauna, including detection in putative parasitoids of infected Orthoptera suggesting a possible transmission path and the opportunity to study local transmission and explore their role in the evolution of New Zealand invertebrates. Expand
Integrated management of ground wētā (Orthoptera: Anostostomatidae) in Marlborough vineyards
TLDR
This PhD work aimed at developing an ecologically-based integrated management strategy for wētā based on an understanding of the biology and ecology of the species associated with vine damage, and confirmed that a single species was associated with bud damage. Expand
The effects of squid-baiting pitfall traps for sampling wētā (Orthoptera) and other ground-dwelling forest invertebrates
TLDR
The higher catches obtained with squid-baiting, suggests this may be a useful modification to increase sampling rates, which is valuable where sampling effort is logistically constrained such as on islands or other remote study sites. Expand
Macroinvertebrate community responses to mammal control - Evidence for top-down trophic effects
TLDR
This paper is intended to provide a history of the field and some of the techniques used, as well as some examples of individual cases, that have been used in the field. Expand

Abstract Although the New Zealand ground wētā (Anostostomatidae: Hemiandrus) are widespread and abundant, little has been described of their ecology and behaviour. Within the genus several lineagesExpand

Improved resolution of cave weta diversity (Orthoptera: Rhaphidophoridae): ecological implications for Te Paki, Far North, New Zealand
TLDR
This study aimed to improve the strategies for cave weta identification and build an understanding of population dynamics and distribution of the taxon across three habitat types in the Te Paki Ecological District. Expand
Diversification of New Zealand weta (Orthoptera: Ensifera: Anostostomatidae) and their relationships in Australasia
TLDR
Molecular dating approaches are used to test the plausibility of alternative biogeographic hypotheses for the origin of the New Zealand anostostomatid fauna and found support for divergence of the main clades at, or shortly after, Gondwanan break-up, and dispersal across the Tasman much more recently.

Phylogenetics of New Zealand's tree, giant and tusked weta (Orthoptera: Anostostomatidae): evidence from mitochondrial DNA
TLDR
Habitat-specialisation in South Island appears to have evolved in response to habitat diversification associated with Pliocene mountain building and little support in the data for the reciprocal monophyly of the tree and giant weta genera is found. Expand
A preliminary survey of altitudinal variation in two ground wētā species, Hemiandrus maculifrons (Walker) and Hemiandrus pallitarsis (Walker) (Orthoptera: Anostostomatidae)
TLDR
Investigation of two species of ground wētā in the Moehau Ecological Area found no evidence of intraspecific variation in body size with altitude, and appear well suited to further investigations into aspects associated with factors that influence body size, distributional range shifts and climate change.

Notes on sexual size dimorphism, sex ratio and movements of adult ground weta Hemiandrus maculifrons (Walker) (Orthoptera: Anostostomatidae)
TLDR
Adult females were significantly larger than males, but capture and re-sight rates suggested males were the more abundant sex during the study period, indicating areas for further research into aspects of sexual selection. Expand
After the deluge: mitochondrial DNA indicates Miocene radiation and Pliocene adaptation of tree and giant weta (Orthoptera: Anostostomatidae)
TLDR
It is hypothesize that at least three distinct groups of weta survived the Oligocene marine transgression and radiated subsequently, and patterns of genetic diversity within species reflect, in some instances, geographical subdivision in the Pliocene, and in other cases, Pleistocene range changes resulting from climate change.

The Use of Tag-Names and New Zealand Taxonomy
TLDR
The use of tag-names lowers the value of systematics research and facilitates a poor science ethic, and it is believed that the endemic use oftag-names should end. Expand
