Amblypygi is an order of arachnid chelicerate arthropods also known as whip spiders or tailless whip scorpions. The name "amblypygid" means "blunt tail", a reference to a lack of the flagellum that is otherwise seen in whip scorpions. Amblypygids possess no silk glands or venomous fangs. They rarely bite if threatened, but can grab fingers with their pedipalps, resulting in thorn-like puncture injuries.
The family Dipluridae, known as curtain-web spiders are a group of spiders in the infraorder Mygalomorphae, that have two pairs of booklungs, and chelicerae (fangs) that move up and down in a stabbing motion. A number of genera, including that of the Sydney funnel-web spider (Atrax), used to be classified in this family but have now been moved to Hexathelidae.
Sicariidae is a family of six-eyed venomous spiders known for their potentially necrotic bites. The family consists of three genera and about 160 species. Well known spiders in this family include the brown recluse spider and the six-eyed sand spider.
Natta is a genus of jumping spiders that was first described by Ferdinand Anton Franz Karsch in 1879. As of July 2019 it contains only two species, found only in Africa and Yemen: N. chionogaster and N. horizontalis.
Thiania is a genus of jumping spiders that was first described by Carl Ludwig Koch in 1846.
Idiopidae, also known as armored trapdoor spiders, is a family of mygalomorph spiders first described by Eugène Simon in 1889. They have a large body similar to tarantulas.
Barychelidae, also known as brushed trapdoor spiders, is a spider family with about 300 species in 42 genera.
Trochanteriidae is a family of spiders first described by Ferdinand Karsch in 1879 containing about 52 species in 6 genera. Most are endemic to Australia though Doliomalus and Trochanteria are from South America and Plator is from Asia. Platyoides species exist in southern and eastern Africa, Madagascar, and the Canary Islands with one species, P. walteri, introduced to Australia.
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. As of August 2022, 1,040 species have been identified, with 156 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes.
Ferdinand Anton Franz Karsch or Karsch-Haack was a German arachnologist, entomologist and anthropologist.
Pelinobius or the king baboon is a monotypic genus of east African tarantulas containing the single species, Pelinobius muticus. It was first described by Ferdinand Anton Franz Karsch in 1885, and is found in Tanzania and Kenya.
The Phaneropterinae, the sickle-bearing bush crickets or leaf katydids, are a subfamily of insects within the family Tettigoniidae. Nearly 2,060 species in 85 genera throughout the world are known. They are also known as false katydids or round-headed katydids.
Anahita is a genus of wandering spiders first described by Ferdinand Karsch in 1879.
Scalidognathus is a genus of Asian armored trapdoor spiders that was first described by Ferdinand Anton Franz Karsch in 1892. Originally placed with the Ctenizidae, it was moved to the Idiopidae in 1985.
Chilobrachys is a genus of Asian tarantulas that was first described by Ferdinand Anton Franz Karsch in 1892. They are found in India, Myanmar, Malaysia, China, Vietnam, Thailand and Sri Lanka. They are usually medium or large-sized, and they can stridulate by using small spines present on the chelicerae.
Holothele is a genus of tarantulas that was first described by Ferdinand Anton Franz Karsch in 1879. Originally placed with the curtain-web spiders, it was transferred to the tarantulas in 1980.
Aetrocantha is a genus of African orb-weaver spiders containing the single species, Aetrocantha falkensteini. It was first described by Ferdinand Karsch in 1879, and has only been found in Central Africa.
Pedinopistha is a genus of Hawaiian running crab spiders that was first described by Ferdinand Anton Franz Karsch in 1880.
Gnathonarium is a genus of dwarf spiders that was first described by Ferdinand Anton Franz Karsch in 1881.
The Selenocosmiinae are a subfamily of tarantulas found throughout South-East Asia and Australia. This subfamily is defined by the presence of a lyra on the maxillae and strikers on the chelicerae, allowing these spiders to stridulate and produce a "hissing" sound. However some species within Phlogiellus may have secondary lost their lyra but retain their strikers. The monophyly of the subfamily has been only tested using genetic data with a handful of genera or species in a few studies. However, these studies found genera that had been previously placed in this subfamily were actual their own separate subfamily (Poecilotheria) and that Selenocosmiinae is most closely related to the Indian Thrigmopoeinae. As of 2021, Selenocosmiinae contains 11 genera.
