Monotypic Araneidae genera

Macracantha is a genus of Asian orb-weaver spiders recognized as containing the species, Macracantha arcuata., although some schemes also recognise inclusion of Gasteracantha hasselti in this genus. Macracantha is notable for the extremely long, curved spines on the abdomens of female members of the genus; Eugène Simon created the taxon name from Ancient Greek μακρός (makrόs), meaning "big", and ἄκανθα (ákantha), meaning "spine". It occurs from India and China through Southeast Asia to Indonesia.

Eustacesia is a genus of South American orb-weaver spiders containing the single species, Eustacesia albonotata. It was first described by Lodovico di Caporiacco in 1954, and has only been found in French Guiana.

Faradja is a genus of Central African orb-weaver spiders containing the single species, Faradja faradjensis. It was first described by M. Grasshoff in 1970, and has only been found in Middle Africa.

Aspidolasius is a genus of South American orb-weaver spiders containing the single species, Aspidolasius branicki. It was first described by Eugène Simon in 1887, and has been found in Colombia, Bolivia, Guyana, and Brazil.

Heterognatha is a genus of South American orb-weaver spiders containing the single species, Heterognatha chilensis. It was first described by H. Nicolet in 1849, and has only been found in Chile.

Hypsacantha is a genus of African orb-weaver spiders containing the single species, Hypsacantha crucimaculata. It was first described by Friedrich Dahl in 1914, and is found from Central to Southern Africa.

Friula is a genus of orb-weaver spiders containing the single species, Friula wallacei. It was first described by O. Pickard-Cambridge in 1897, and has been found only on Borneo. Pickard-Cambridge based his description and drawing on a specimen collected by Alfred Russel Wallace in Sarawak between November 1854 and January 1856. Pickard-Cambridge personally confirmed with Wallace that Wallace "was the captor of this spider, and in the locality mentioned." In 2017, the Alfred Russel Wallace Memorial Fund published a call for observations of this species, stating that no specimens of the species

Actinosoma is a genus of orb-weaver spiders containing the single species, Actinosoma pentacanthum. It was first described by E. L. Holmberg in 1883, and is found throughout South America, from Colombia to Argentina.

Madacantha is a genus of East African orb-weaver spiders containing the single species, Madacantha nossibeana. It was first described by M. Emerit in 1970, and has only been found in Madagascar.

Actinacantha is a genus of Southeast Asian orb-weaver spiders containing the single species, Actinacantha globulata. It was first described by Eugène Simon in 1864, and has only been described from Sumatra, Java in Indonesia.

Lariniaria is a genus of Asian orb-weaver spiders containing the single species, Lariniaria argiopiformis. It was first described by M. Grasshoff in 1970, and has only been found in Russia, China, Korea, and Japan.

Thelacantha (Asian spinybacked orbweaver) is a genus of orb-weaver spiders containing the single species, Thelacantha brevispina. It was first described by in 1882, and has been found in Australia, Madagascar, the Indian subcontinent, and Southeast Asia, as well as parts of Japan. It has also been introduced into Hawaii. T. brevispina is closely related to those in the genus Gasteracantha and was briefly synonymized with it in 1859, but revalidated in 1974. Saito described three other Thelacantha species in 1933, which were later synonymized with T. brevispina.

Epeiroides is a genus of orb-weaver spiders containing the single species, Epeiroides bahiensis. It was first described by Eugen von Keyserling in 1885, and has only been found in Costa Rica and Brazil.

Colphepeira is a genus of North American orb-weaver spiders containing the single species, Colphepeira catawba. It was first described by Allan Frost Archer in 1941, and has only been found in United States and Mexico.

Encyosaccus is a genus of South American orb-weaver spiders containing the single species, Encyosaccus sexmaculatus. It was first described by Eugène Simon in 1895, and has only been found in Colombia, Ecuador, Peru, and Brazil.

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 West and Central Africa.

Allocyclosa is a genus of orb weaver spiders that contains only one species, Allocyclosa bifurca. It was first described in 1887 by McCook under the name Cyrtophora bifurca, and was transferred to its own genus in 1999. It is the only Cyclosa species north of Mexico to have a forked rear tip of the abdomen hence the name bifurca, Latin for "two-pronged". The forked tip of the abdomen, bearing two humps shaped like the letter M, is a defining feature in both males and females, though it is similar to features present in certain Cyrtophora species. Both sexes are a grey-green color, though only

Aethrodiscus is a genus of African orb-weaver spiders containing the single species, Aethrodiscus transversalis. It was first described by Embrik Strand in 1913, and has only been found in Central Africa.

Afracantha is a genus of African orb-weaver spiders containing the single species, Afracantha camerunensis. It was first described by Friedrich Dahl in 1914, and has only been found in Africa.

Austracantha is a genus of spider with a single species, Austracantha minax, commonly known as the jewel spider or the Christmas spider. It is a member of the family Araneidae (the orb-weavers) and is endemic to Australia. They are relatively small spiders, reaching a maximum total body length of only around for females, and for males. Their abdomen has six distinctive projections ("spines") that makes them easy to identify. They are predominantly a shiny black, with variable white, yellow, and orange patterns. Melanistic forms also occur during autumn. They are facultatively gregarious, and c

Cyrtobill is a genus of Australian orb-weaver spiders containing the single species, Cyrtobill darwini. It was first described by V. W. Framenau & N. Scharff in 2009, and has only been found in Australia.
