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.
The Tooth Cave spider, formerly Neoleptoneta myopica, now Tayshaneta myopica, is a 1.6 mm long spider in the family Leptonetidae. It is endemic to limestone caves near Austin, Texas in the United States and is considered an endangered species.
Leptonetidae is a family of small spiders adapted to live in dark and moist places such as caves. The family is relatively primitive having diverged around the Middle Jurassic period. They were first described by Eugène Simon in 1890.
Myrmarachne is a genus of ant-mimicking jumping spiders that was first described by W. S. MacLeay in 1839. They are commonly called ant-mimicking spiders, but they are not the only spiders that have this attribute. The name is a combination of Ancient Greek μύρμηξ, meaning "ant", and ἀράχνη, meaning "spider".
Alfenus is a genus of jumping spiders.
Necatia is a genus of the jumping spider family Salticidae. Its only species, Necatia magnidens, is found in southern China.
Hyllus is a genus of the spider family Salticidae. Most species occur in Africa and Madagascar, with many in Australasia and north to India. H. insularis is found in Greece and Iran, but it is considered misplaced in this genus, and is now Evarcha insularis.
Ochyroceratidae is a six-eyed spider family, with 165 described species in ten genera. They are common inhabitants of caves and the tropical forest litter of South Africa, the Caribbean, Asia and South America. Considered an ecological counterpart of the Linyphiidae of the northern temperate zone, species are especially diverse in the Indo-Pacific region.
Telemidae, also known as long-legged cave spiders, is a family of small haplogyne spiders. Most are cave dwelling spiders with six eyes, though some do not have any eyes at all. There are about 104 described species in sixteen genera.
The Leptonetoidea are a superfamily of haplogyne araneomorph spiders with three families. Phylogenetic studies have provided weak support for the relationship among the families. The placement of one of the families within the Haplogynae has been questioned.
The Haplogynae or haplogynes are one of the two main groups into which araneomorph spiders have traditionally been divided, the other being the Entelegynae. Morphological phylogenetic studies suggested that the Haplogynae formed a clade; more recent molecular phylogenetic studies refute this, although many of the ecribellate haplogynes do appear to form a clade, Synspermiata.
Trogloraptor is a genus of large spiders found in the caves of southwestern Oregon. It is the sole genus in the family Trogloraptoridae, and includes only one species, Trogloraptor marchingtoni. These spiders are predominantly yellow-brown in color with a maximum leg span of 3 in (7.6 cm). They are remarkable for having hook-like claws on the raptorial last segments of their legs.
Bannana is a genus of goblin spiders native to Xishuangbanna prefecture, Yunnan Province, China, where it lives in the leaf-litter of tropical rainforest. There are two known species: Bannana crassispina and B. parvula, both described in 2015. Individuals are pale yellow and unpatterned, and range from around 1.0 to 1.8 mm in body length, with females being slightly larger than males. The eyes are reduced or entirely absent. Known only from a nature reserve in Xishuangbanna, Bannana belongs to a group of Asian goblin spiders known as the "Dysderoides complex", that ranges from China to Pakistan and south to Indonesia.
Telema is a genus of long-legged cave spiders that was first described by Eugène Louis Simon in 1882.
Telemofila is a genus of long-legged cave spiders that was first described by J. Wunderlich in 1995. As of September 2019 it contains two species, found on Sumatra and New Caledonia: T. pecki and T. samosirensis.
Usofila is a genus of American long-legged cave spiders that was first described by Eugen von Keyserling in 1891. Originally placed with the Ochyroceratidae, it was transferred to the Telemidae in 1973.
Yoroa is a genus of South Pacific comb-footed spiders that was first described by L. Baert in 1984. As of June 2020 it contains two species, found in Australia and Papua New Guinea: Y. clypeoglandularis and Y. taylori.
Neaetha irreperta is a species of jumping spider in the genus Neaetha that lives in South Africa and Tanzania. First described in 2000 by Wanda Wesołowska & Anthony Russell-Smith, the spider is small, with a dark brown carapace that is between 1.2 and 1.4 mm long and a deep red-brown abdomen between 1.1 and 1.5 mm long. The abdomen has a pattern that is indistinct on the male, but a clearer set of grey lines and marks on the female, and this, along with the width of the abdomen, distinguishes the species from other in the genus. The male has a long embolus and the female's sclerotized epigyne has a central pocket and wide copulatory openings.
