Tivodrassus
''Tivodrassus'' is a genus of Mexican long-spinneret ground spiders that was first described by Ralph Vary Chamberlin & Vaine Wilton Ivie in 1936. It was transferred to the ground spiders in 2018, but was returned to ''Prodidominae'' in 2022.

Prodidominae
Prodidominae is a family of spider, sometimes called long-spinneret ground spiders. It was formerly regarded as a subfamily of Gnaphosidae, but was raised to a family in 2022. Spiders in the family are easily identified by the greatly elongated base of the piriform gland spigots. At least parts of their body are covered with shiny scales or setae. The posterior median eyes are flat and silvery, with a triangular, egg-shaped or irregularly rectangular shape.Barbara BaehrProdidomidae/ref> Biology Spiders in the Prodidominae are ground dwellers. Most species are nocturnal and hide during the day in litter, but ''Myandra'' species, which are probably mimicking ants, seem to be active during the day. The genus ''Zimiris'' is synanthropic and thus found throughout the tropics. Distribution Although ''Theuma walteri'' was described from Turkmenistan by Eugène Simon, it is suspected that Simon accidentally exchanged its locality with that of ''Anagraphis pallens'' (Gnaphosidae); the ...

Ralph Vary Chamberlin
Ralph Vary Chamberlin (January 3, 1879October 31, 1967) was an American biologist, ethnographer, and historian from Salt Lake City, Utah. He was a faculty member of the University of Utah for over 25 years, where he helped establish the School of Medicine and served as its first dean, and later became head of the zoology department. He also taught at Brigham Young University and the University of Pennsylvania, and worked for over a decade at the Museum of Comparative Zoology at Harvard University, where he described species from around the world. Chamberlin was a prolific taxonomist who named over 4,000 new animal species in over 400 scientific publications. He specialized in arachnids (spiders, scorpions, and relatives) and myriapods (centipedes, millipedes, and relatives), ranking among the most prolific arachnologists and myriapodologists in history. He described over 1,400 species of spiders, 1,000 species of millipedes, and the majority of North American centipedes, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilton Ivie
Vaine Wilton Ivie (March 28, 1907 – August 8, 1969) was an American arachnologist, who described hundreds of new species and many new genera of spiders, both under his own name and in collaboration with Ralph Vary Chamberlin. He was employed by the American Museum of Natural History in New York. He also was a supporter of the Technocracy movement. Biography Wilton Ivie was born in Eureka, Utah on March 28, 1907. He attended the University of Utah earning a BSc in 1930 and an MSc in 1932, working under Ralph V. Chamberlin. He remained at Utah as an instructor in zoology from 1932 to 1947, during which time he continued to work on spiders. For the last nine years of his life he worked at the American Museum of Natural History. He died as a result of an auto accident in Kansas on 8 August 1969, during an expedition for the American Museum of Natural History. Taxonomic works Ivie published many texts of information on spiders, often with Chamberlin, for example, ''New ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of Taxonomy (biology), 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 reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), 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 binomial nomenclature, 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 specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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. phylogenetic analysis should c ...

Ground Spider
Ground spiders comprise Gnaphosidae, the seventh largest spider family with over 2,000 described species in over 100 genera distributed worldwide. There are 105 species known to central Europe, and common genera include '' Gnaphosa'', '' Drassodes'', '' Micaria'', '' Cesonia'', '' Zelotes'' and many others. They are closely related to Clubionidae. At present, no ground spiders are known to be seriously venomous to humans. Description Generally, ground spiders are characterized by having barrel-shaped anterior spinnerets that are one spinneret diameter apart. The main exception to this rule is found in the ant-mimicking genus ''Micaria''. Another characteristic is an indentation in the endites (paired mouthparts anterior and lateral to the labium, or lip). All ground spiders lack a prey-capture web and generally run prey down on the surface. They hunt at night and spend the day in a silken retreat. The genitalia are diverse and are a good model for studying the evolution of genit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
