Corinnidae is a family of araneomorph spiders, sometimes called corinnid sac spiders. The family, like other "clubionoid" families, has a confusing taxonomic history. Once it was a part of the large catch-all taxon Clubionidae, now very much smaller. The original members of the family are apparently similar only in that they have eight eyes arranged in two rows, conical anterior spinnerets that touch and are generally wandering predators that build silken retreats, or sacs, usually on plant terminals, between leaves, under bark or under rocks.
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.
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.
Chlorocypha is a genus of damselflies in the family Chlorocyphidae.
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. As of December 2023, 1,100 species have been identified, with 166 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.

It is distributed widely across tropical and subtropical southeastern Asia, including Indonesia, Brunei, Malaysia, Myanmar, Philippines, Singapore, Cambodia, Laos, Thailand, Vietnam, India, and China (Hainan). It is notable for containing some of the largest living species of scorpions.

Isometrus is a genus of scorpion belonging and being eponymous to the family Buthidae. Some species are currently assigned to the genus Reddyanus.
Bassaniana, commonly called bark crab spiders, is a widespread genus of crab spiders that was first described by Embrik Strand in 1928.
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.
Bianor angulosus, is a species of spider of the genus Bianor. It is found in Sri Lanka, India to China, Vietnam, and Indonesia.

Arkyidae, also known as triangular spiders, is a family of araneomorph spiders first described by Ludwig Carl Christian Koch in 1872 as a subfamily of Araneidae, and later elevated to a full family in 2017.
Heterothele is a genus of South American and African tarantulas that was first described by Ferdinand Anton Franz Karsch in 1879.
Schismatothele is a genus of South American tarantulas that was first described by Ferdinand Anton Franz Karsch in 1879.
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.
Hexophthalma is a genus of spiders in the family Sicariidae. Although the genus was originally erected in 1878, it was merged into the genus Sicarius in the 1890s, and remained unused until revived in 2017, when it was discovered that the African species then placed in Sicarius were distinct. The English name six-eyed sand spiders is used for members of the genus, particularly Hexophthalma hahni.
