Macrobunidae
Macrobunidae is a family of araneomorph spiders. It was treated as a subfamily of Amaurobiidae until elevated to a full family based on a 2023 molecular phylogenetic study. Taxonomy A 2023 molecular phylogenetic study of the 'marronoid' group of initially nine spider families led to a changed circumscription of some of the families, including two resurrected or new families, Cicurinidae and Macrobunidae. The relationships in the study's maximum likelihood summary tree are shown below. The subfamily Macrobuninae was originally created as part of the family Amaurobiidae, but in the study was shown to be a monophyletic group well removed from Amaurobiidae. Accordingly it was raised to family rank. Genera , the World Spider Catalog accepted the following genera, all formerly placed in the family Amaurobiidae: *'' Anisacate'' Mello-Leitão, 1941 *'' Auximella'' Strand, 1908 *'' Callevopsis'' Tullgren, 1902 *'' Cavernocymbium'' Ubick, 2005 *'' Chresiona'' Simon, 1903 *'' Chumma'' Joc ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Australia, officially the Commonwealth of Australia, is a country comprising mainland Australia, the mainland of the Australia (continent), Australian continent, the island of Tasmania and list of islands of Australia, numerous smaller islands.

Spider
Spiders (order (biology), order Araneae) are air-breathing arthropods that have eight limbs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude spider silk, silk. They are the largest order of arachnids and rank seventh in total species diversity among all Order (biology), orders of organisms. Spiders are found worldwide on every continent except Antarctica, and have become established in nearly every land habitat. , 53,034 spider species in 136 Family (biology), families have been recorded by Taxonomy (biology), taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomy, Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segmentation (biology), segments are fused into two Tagma (biology), tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindr ...

Valerie Todd Davies
Valerie Todd Davies (born 29 September 1920 in Makirikiri, near Wanganui, New Zealand, died 29 October 2012 in Brisbane, Queensland) was an arachnologist who described many species of spider. Early life Valerie Ethel Todd (later Valerie Davies after her marriage) was born 29 September 1920 in Makirikiri, near Wanganui, in New Zealand. She attended Wanganui Girls' College and then studied her BSc at Victoria University in Wellington in 1939. She continued her studies toward a MSc at Otago University in Dunedin, graduating in 1943. Her thesis researched trap-door spiders. Upon graduation she worked as a research assistant and later an assistant lecturer in zoology at Otago University. Todd was awarded a post-graduate travelling scholarship in science to Somerville College, Oxford, where she completed her PhD. She returned to Dunedin in 1948 to marry George Davies, who was a lecturer in dentistry at the University of Otago. Move to Australia The Davies family moved to Brisba ...

Spiders Of Australia
Australia has a number of highly venomous spiders, including the Sydney funnel-web spider, its relatives in the family Hexathelidae, and the redback spider, whose bites can be extremely painful and have historically been linked with deaths in medical records. Most Australian spiders do not have venom that is considered to be dangerously toxic. No deaths caused by spider bites in Australia have been substantiated by a coronial inquest since 1979. There are sensationalised news reports regarding Australian spiders that fail to cite evidence. ''A Field Guide to Spiders of Australia'' published by CSIRO Publishing in 2017 featuring around 836 species illustrated with photographs of live animals, around 381 genera and 78 families, introduced significant updates to taxonomy from Ramirez, Wheeler and Dmitrov. Estimates put the total number of Australian spider species at about 10,000. Only around 3,600 have been described. Little information is known about many undiscovered species. New ...
