Multiple hybridization events and repeated evolution of homoeologue expression bias in parthenogenetic, polyploid New Zealand stick insects.

During hybrid speciation, homoeologues combine in a single genome. Homoeologue expression bias (HEB) occurs when one homoeologue has higher gene expression than another. HEB has been well characterized in plants but rarely investigated in animals, especially invertebrates.

Wing pattern variation and DNA barcodes defy taxonomic splitting in the New Zealand Pimelea Looper Notoreas perornata (Walker) (Lepidoptera: Geometridae: Larentiinae): the importance of populations as conservation units.

The endemic Notoreas perornata (Walker, 1863) complex (Lepidoptera: Geometridae: Larentiinae) from the North Island and northern South Island of New Zealand is reviewed. Larvae feed on Pimelea spp. (Thymelaeaceae), frequently in highly fragmented and threatened shrubland habitats.

Fast-tracking bespoke DNA reference database generation from museum collections for biomonitoring and conservation.

Despite recent advances in high-throughput DNA sequencing technologies, a lack of locally relevant DNA reference databases limits the potential for DNA-based monitoring of biodiversity for conservation and biosecurity applications. Museums and national collections represent a compelling source of authoritatively identified genetic material for DNA database development, yet obtaining DNA barcodes from long-stored specimens may be difficult due to sample degradation. Here we demonstrate a sensitive and efficient laboratory and bioinformatic process for generating DNA barcodes from hundreds of invertebrate specimens simultaneously via the Illumina MiSeq system.

Dataset of host records for introduced parasitoid wasp species (Hymenoptera) in New Zealand.

Background: The introduction of species to new regions is occurring at an increasing rate. These introductions typically consist of species that are deliberately introduced for the purposes of biological control of pests or of species that are accidentally introduced through human-mediated transport networks.Understanding the potential and actual impacts of these introduced species requires comprehensive information on their geographic distributions and biological associations.

Systematics of the New Zealand Weevil Etheophanus Broun (Curculionidae: Molytinae).

Etheophanus Broun is considered a molytine based on the form of the pharyngeal plate, presence of a small spiculum relictum in the male, and presence of a pair of small internal apodemes on the antero-lateral corners of the 5th abdominal ventrite of the female. Examination of primary type specimens and newer material confirm one new species Etheophanus kuscheli sp. n.
