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 Brisban ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malkaridae
Malkaridae is a small family of araneomorph spiders first described by Valerie Todd Davies in 1980. In 2017, the family Pararchaeidae was brought into synonymy with Malkaridae. Genera , the World Spider Catalog accepts the following genera: *''Anarchaea'' Rix, 2006 — Australia *'' Carathea'' Moran, 1986 — Australia *''Chilenodes'' Platnick & Forster, 1987 — Chile, Argentina *''Flavarchaea'' Rix, 2006 — Australia *''Forstrarchaea'' Rix, 2006 — New Zealand *''Malkara'' Davies, 1980 — Australia *''Nanarchaea'' Rix, 2006 — Australia *''Ozarchaea'' Rix, 2006 — Australia, New Zealand *''Pararchaea'' Forster, 1955 — New Zealand *''Perissopmeros'' Butler, 1932 — Australia *''Westrarchaea'' Rix, 2006 — Australia *''Whakamoke ''Whakamoke'' is a genus of Polynesian shield spiders.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. 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 ...

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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiders Described In 1980
Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separ ...
