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 ...

Mesothelae
The Mesothelae are a suborder of spiders (order Araneae). , two extant families were accepted by the World Spider Catalog, Liphistiidae and Heptathelidae. Alternatively, the Heptathelidae can be treated as a subfamily of a more broadly circumscribed Liphistiidae. There are also a number of extinct families. This suborder is thought to form the sister group to all other living spiders, and to retain ancestral characters, such as a segmented abdomen with spinnerets in the middle and two pairs of book lungs. Extant members of the Mesothelae are medium to large spiders with eight eyes grouped on a tubercle. They are found only in China, Japan, and southeast Asia. The oldest known Mesothelae spiders are from the Carboniferous, over 300 million years ago. Taxonomy Reginald Innes Pocock in 1892 was the first to realize that the exceptional characters of the genus '' Liphistius'' (the only member of the group then known) meant that it was more different from the remaining spiders th ...

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] |
Ryuthela
''Ryuthela'' is a spider genus in the family Heptathelidae. This genus, as well as their closest relatives, ''Heptathela'', formed when land masses from present-day Japan separated from the rest of Asia Asia ( , ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which ..., forming islands in the late Miocene. Speciation of ''Ryuthela'' and ''Heptathela'' also occurred during this time, because of the further separation of islands, causing allopatric speciation. They exhibit intraspecific variation in female genitalia despite being morphologically alike. Male spiders live only a few weeks after reaching maturity whereas female spiders can live up to 10 to 20 years (Huber, T. & Haug, C., 2021).

Luthela
''Luthela'' is a genus of spiders in the family Heptathelidae, found in China. Taxonomy The genus ''Luthela'' was erected in 2022 with the type species '' Luthela yiyuan''. Five further new species were described. The species ''Heptathela sinensis'' had been described in 1932 based on a female specimen, and transferred to the new genus ''Sinothela'' in 2003 based on a male specimen that cannot be confidently matched to the female, so the authors of ''Luthela'' regard both ''Sinothela sinensis'' and ''Sinothela'' to be (dubious names). Accordingly, two species that had been placed in ''Sinothela'' were transferred to ''Luthela''. Three further new species were added to the genus in 2023.
