The number of described species on the planet is about 1.9 million, with ca. 17,000 new species described annually, mostly from the tropics. However, taxonomy is usually described as a science in crisis, lacking manpower and funding, a politically acknowledged problem known as the Taxonomic Impediment. Using data from the Fauna Europaea database and the… (More)
The Assassin Spiders of the family Archaeidae are an ancient and iconic lineage of basal araneomorph spiders, characterised by a specialised araneophagic ecology and unique, 'pelican-like' cephalic morphology. Found throughout the rainforests, wet sclerophyll forests and mesic heathlands of south-western, south-eastern and north-eastern Australia, the genus… (More)
The Assassin Spiders of the family Archaeidae from southern Australia are revised, with a new genus (Zephyrarchaeagen. n.) and nine new species described from temperate, mesic habitats in southern Victoria, South Australia and south-western Western Australia: Zephyrarchaea austinisp. n., Zephyrarchaea barrettaesp. n., Zephyrarchaea grayisp. n.,… (More)
A taxonomic review of the endemic Western Australian millipede genus Boreohesperus Shear is presented in which six species are recognized: the type species, Boreohesperus capensis Shear, 1992, from North-West Cape, one new species, Boreohesperus dubitalis, from Barrow Island and four more new species from the Pilbara region, Boreohesperus curiosus,… (More)
Native speech perception is generally assumed to be highly efficient and accurate. Very little research has, however, directly examined the limitations of native perception, especially for contrasts that are only minimally differentiated acoustically and articulatorily. Here, we demonstrate that native speech perception may indeed be more difficult than is… (More)

The articulation of con-trastive and non-contrastive pre-stopped consonants in Kaytetye, In Proceedings of the 18th International Congress of Phonetic Sciences. An ultrasound investigation into articulatory variation into American /s/ and /r/, In Proceedings of the 18th International Congress of Phonetic Sciences.
1 Introduction Kaytetye is an Arandic language of central Australia with approximately 200 speakers. As shown in Table 1, Kaytetye contrasts plain nasals with pre-stopped nasals, an unusual feature for an Australian language. Pre-stopping of both nasals and later-als is common in Australian languages, but it is not typically contrastive (Butcher, 2006;… (More)
