Rigoutorum new genus Hutchinson & Moeseneder (Coleoptera: Scarabaeidae: Cetoniinae: Schizorhinini: Schizorhinina) is created for Diaphonia bacchusi Rigout & Allard, 1997, resulting in Rigoutorum bacchusi new combination. Rigoutorum jakli Hutchinson & Moeseneder, new species, which has been lumped with R. bacchusi in collections and confirmed as dis...
Article
Molecular studies using COI and 28S sequence data strongly identify a clade within the Heterolepismatinae distinct from the majority of species so far sequenced. The independence of the clade is supported by several morphological characters including a glabrous anterior margin to the frons, large trapezoidal thoracic sternites, tarsal trichobothria...
Article
DNA sequence data was derived for all five described species of Petalura Leach, 1815, for eight gene fragments from the mitochondrial and nuclear genomes. Phylogenetic analyses suggest that there are only four clearly distinct species in the genus. They are Pet alura gigantea, P. hesperia, P. ingentissima, and P. litorea. Petalura pulcherrima Tilly...
Article
The noctuid genus Spodoptera currently consists of 31 species with varied host plant breadths, ranging from monophagous and oligophagous non-pest species to polyphagous pests of economic importance. Several of these pest species have become major invaders, colonizing multiple continents outside their native range. Such is the case of the infamous f...

Background: Processed seafood products are not readily identifiable based on physical characteristics, which leaves the industry vulnerable to high levels of product mislabelling (globally estimated at 5-30% mislabelled). This is both a food safety issue and a consumer protection issue as cheaper species could be substituted for more expensive spe...
Article
Full-text available
Lepidopteran stemborers are among the most damaging agricultural pests worldwide, able to reduce crop yields by up to 40%. Sugarcane is the world’s most prolific crop, and several stemborer species from the families Noctuidae, Tortricidae, Crambidae and Pyralidae attack sugarcane. Australia is currently free of the most damaging stemborers, but bio...
Article
Moth borers present a major biosecurity threat to the Australian sugarcane industry, particularly the diverse and under studied fauna of Southeast Asia. Accurate identification of moth borer species is very challenging as adults generally lose key external diagnostic characters through incorrect handling. However, genitalia dissections yield robust...

The introduction of domesticated animals into new environments can lead to considerable ecological disruption, and it can be difficult to predict their impact on the new ecosystem. In this study, we use faecal metabarcoding to characterize the diets of three ruminant taxa in the rangelands of south-western New South Wales, Australia. Our study orga...
Article
Thoracolopha was described by Turner in 1939 for Thoracolopha alychnodes, Thoracolopha plaesiospila and Thoracolopha pissonephra, with the last designated as the type species. In 1996, Edwards referred all three taxa to Proteuxoa Hampson, 1903, thus synonymising Thoracolopha with Proteuxoa. However, the genitalia of Proteuxoa pissonephra are not li...
Article
A new and very occasional pest of lychee trees (Litchi chinensis) was recently identified from New Caledonia—the endemic weevil Acanthopygus griseus Montrouzier, 1861 (Coleoptera: Anthribidae). This is the first report of an anthribid weevil causing significant damage to living trees.
Article
There is mounting evidence that non-crop vegetation can promote natural enemies of crop pests but most studies use only one or a few approaches to explore key processes. Here we integrate field sampling, insect marking, insecticide disruption, and molecular gut content analysis to explore the potential value of non-crop habitats to predators of bra...
Article
A morphological and molecular review of the genus Orosius Distant (Deltocephalinae: Opsiini) was undertaken using male genitalia and DNA barcoding. We recognise 14 valid species of the genus, of which two were indeterminate, based on females only and recognised only by DNA barcodes. Orosius argentatus (Evans) stat. rev. is removed from synonymy wit...

DNA barcoding is all too often derided by taxonomists with little understanding of how far this emerging subdiscipline of systematics has progressed since it was proposed by Hebert et al. (2003). A prime example is Ebach’s factually incorrect and misleading recent correspondence (Ebach 2011). Ebach and I agree on one point: indeed many readers of Z...
