The spider family Liphistiidae, recognized by Tamerlan Thorell in 1869, when broadly circumscribed to include two subfamilies, comprises 8 genera and about 100 species of medium-sized spiders from Southeast Asia, China, and Japan. They are among the most basal living spiders, belonging to the suborder Mesothelae. In Japan, the Kimura spider is well known. In 2022, it was proposed to re-accept the subfamily Heptathelinae as the family Heptathelidae. As of December 2023, this proposal was accepted by the World Spider Catalog. In this circumscription, the family Liphistiidae has only one genus, Liphistius.
Onomastus is a genus of Asian jumping spiders that was first described by Eugène Louis Simon in 1900. It is the only genus in the subfamily Onomastinae.
Tetrablemmidae, sometimes called armored spiders, is a family of tropical araneomorph spiders first described by Octavius Pickard-Cambridge in 1873. It contains 126 described species in 29 genera from southeast Asia, with a few that occur in Africa and Central and South America. Pacullidae was incorporated into this family in 1981, but was later restored as a separate family in a 2016 phylogenetic study.
Pacullidae is a family of araneomorph spiders first described by Eugène Simon in 1894. It was merged into Tetrablemmidae in 1958, then raised back to family status after a large phylogenetic study in 2017.
Cyclocosmia is a genus of mygalomorph trapdoor spiders in the family Halonoproctidae, first described by Anton Ausserer in 1871. Originally placed with the Ctenizidae, when the family split in 2018, this genus was placed with the Halonoproctidae as the type genus. The name is derived from the Greek "kyklos" (κυκλος), meaning "circle", and "kosmeo" (κοσμεω), meaning "to adorn".
Utivarachna is a genus of Asian araneomorph spiders in the family Trachelidae first described by Kyukichi Kishida in 1940. It was largely ignored until Christa L. Deeleman-Reinhold revised the sac and ground spiders in 2001, transferring some species from Trachelas and adding several new ones. The genus was further expanded in 2014 and 2015.
Brignoliella is a genus of araneomorph spiders in the family Tetrablemmidae that was first described by W. A. Shear in 1978.
Pahanga is a genus of Asian araneomorph spiders in the family Tetrablemmidae that was first described by W. A. Shear in 1979.
Ablemma is a genus of araneomorph spiders in the family Tetrablemmidae that was first described by Carl Friedrich Roewer in 1963.
Bacillemma is a monotypic genus of Thai araneomorph spiders in the family Tetrablemmidae containing the single species, Bacillemma leclerci. It was first described by Christa Laetitia Deeleman-Reinhold in 1993, and is found in Thailand.
Choiroblemma is a genus of Indian araneomorph spiders in the family Tetrablemmidae that was first described by J. D. Bourne in 1980. As of September 2019 it contains two species, found in India: C. bengalense and C. rhinoxunum.
Lamania is a genus of Southeast Asian araneomorph spiders in the family Pacullidae that was first described by Pekka T. Lehtinen in 1981. Originally placed with the armored spiders, it was moved to the Pacullidae in 2017.
Lehtinenia is a genus of Asian araneomorph spiders in the family Tetrablemmidae that was first described by Y. F. Tong & S. Q. Li in 2008. As of September 2019 it contains three species, found in Asia: L. arcus, L. bicornis, and L. bisulcus. It is named in honor of Pekka T. Lehtinen.
Paculla is a genus of araneomorph spiders in the family Pacullidae that was first described by Eugène Louis Simon in 1887. Originally placed with the Tetrablemmidae, it was transferred to the Pacullidae after a 2017 genetic study.
Perania is a genus of Asian araneomorph spiders in the family Pacullidae that was first described by Tamerlan Thorell in 1890. It is considered a senior synonym of Mirania.
Sabahya is a genus of Indonesian araneomorph spiders in the family Pacullidae that was first described by Christa Laetitia Deeleman-Reinhold in 1980. As of September 2019 it contains two species, found on Borneo: S. bispinosa and S. kinabaluana. Originally placed with the Tetrablemmidae, it was moved to the Pacullidae after a 2017 genetic study.
Singaporemma is a genus of Asian araneomorph spiders in the family Tetrablemmidae that was first described by W. A. Shear in 1978.
Christa Laetitia Deeleman-Reinhold is a Dutch arachnologist. She specializes in spiders from Southeast Asia and Southern Europe, particularly cave-dwelling and tropical spiders. She donated a collection of about 25,000 Southeast Asian spiders, the largest collection of Southeast Asian spiders in existence, to the Naturalis Biodiversity Center in Leiden. In addition to numerous articles, she has written the book Forest Spiders of South East Asia (2001).
Phintelloides is a genus of Asian jumping spiders erected by N. Kanesharatnam and Benjamin in 2019 after a molecular phylogenetic study of similar Asian Salticidae species. The single most likely cladogram shows that Phintelloides is sister to Phintella, with Proszynskia sister to both:
