Liphistiidae
The spider family Liphistiidae was first recognized by Tamerlan Thorell in 1869. When narrowly circumscribed, it comprises a single genus '' Liphistius'', native to Southeast Asia; , this was the circumscription accepted by the World Spider Catalog. The family contains the most basal living spiders, belonging to the suborder Mesothelae. The family has also been circumscribed more broadly to include the family Heptathelidae as a subfamily, Heptathelinae, with the narrowly circumscribed Liphistiidae becoming the subfamily Liphistiinae. Taxonomy The family Liphistiidae was erected by Tamerlan Thorell in 1869 for the genus ''Liphistius''. Initially, it was the only family placed in the suborder Mesothelae. In 1923, Kyukichi Kishida described a new genus, '' Heptathela'', and suggested creating two tribes within the Liphistiidae corresponding to the genera ''Liphistius'' and ''Heptathela''. In 1939, Alexander Petrunkevitch raised the tribe Heptatheleae to a separate family, Heptathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Liphistiidae Species
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole". Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help ...

Heptathelidae
Heptathelidae is a family of spiders. It has been sunk within the family Liphistiidae as the subfamily Heptathelinae, but was accepted by the World Spider Catalog. It is placed in suborder Mesothelae, which contains the most basal living spiders. Taxonomy The group was first proposed by Kyukichi Kishida in 1923, when he described a new genus, '' Heptathela'', and suggested creating two tribes within the family Liphistiidae, with ''Heptathela'' placed in Heptatheleae. In 1939, Alexander Petrunkevitch raised the tribe Heptatheleae to a separate family, Heptathelidae. In 1985, Robert Raven reunited the two families, a view supported by Breitling in 2022. Other authors have maintained two separate families, a position accepted by the World Spider Catalog . Phylogeny Molecular phylogenetic studies have repeatedly shown that the family is monophyletic. One possible relationship between the genera is shown in the following Bayesian cladogram (numbers in parentheses give the number of ...

Spiders Of Asia
Spiders ( order Araneae) are air-breathing arthropods that have eight limbs, 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 Antarctica, and have become established in nearly every land habitat. , 53,034 spider species in 136 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 se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
