The Araneomorphae are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to the Mygalomorphae, where they point straight down. Araneomorphs comprise the vast majority of living spiders.
Norman Ira Platnick was an American biological systematist and arachnologist. At the time of his death, he was a professor emeritus of the Richard Gilder Graduate School and Peter J. Solomon Family Curator Emeritus of the invertebrate zoology department of the American Museum of Natural History. A 1973 Ph.D. recipient at Harvard University, Platnick described over 1,800 species of spiders from around the world, making him the second most prolific spider taxonomist in history, behind only Eugène Simon. Until 2014 he was also the maintainer of the World Spider Catalog, a website formerly hosted by the AMNH which tracks the arachnology literature, and attempts to maintain a comprehensive list, sorted taxonomically, of every species of spider which has been formally described. In 2007 he received the International Society of Arachnology's Bonnet award, named for Pierre Bonnet, in recognition of his work on the catalog.
Hindumanes is a genus of jumping spiders found in India. It was first described by Dmitri Logunov in 2004. The name Hindumanes is a portmanteau of "Hinduism", the dominant religion of India, and Lyssomanes, the genus H. karnatakaensis was initially assigned to. As of May 2024, two species have been described:
Spelungula is a monotypic genus of South Pacific large-clawed spiders containing the single species, Spelungula cavernicola, or the Nelson cave spider.
Aphonopelma seemanni, the Costa Rican zebra tarantula, also known as the striped-knee tarantula, is a species of tarantula inhabiting most of western Costa Rica and other parts of Central America, such as Honduras and Nicaragua, and possibly Guatemala. It is usually black with white stripes near the leg joints, but a brown color form also exists for the spider.
Kokomopterus is a genus of prehistoric eurypterid. The genus contains a single species, Kokomopterus longicaudatus, known from the Silurian of Kokomo, Indiana.
Ryuthela is a spider genus in the family Heptathelidae. This genus, as well as their closest relatives, Heptathela, formed when land masses from present-day Japan separated from the rest of Asia, forming islands in the late Miocene. Speciation of Ryuthela and Heptathela also occurred during this time, because of the further separation of islands, causing allopatric speciation.
Ryuthela nishihirai is a species of spider in the family Liphistiidae. They thrive on the Japanese islands of Okinawa.
Omothymus is a genus of spiders in the family Theraphosidae, found in Malaysia, Indonesia and Singapore.
Pardosa tesquorum is a spider in the genus Pardosa, in the family Lycosidae . The distribution range of Pardosa tesquorum includes Russia, Mongolia, China, the US, and Canada.
Erigone autumnalis is a species of dwarf spiders in the family Linyphiidae. It is found in North and Central America, and it has been introduced to Azores, Europe, United Arab Emirates, and New Caledonia.
Kaira alba, the pale frilled orbweaver, is a species of orb weaver in the family Araneidae. It is found in the US and Mexico.
Neon pixii is a species of jumping spider in the family Salticidae. It is found in the United States.
Olios giganteus is a large species of huntsman spider in the family Sparassidae. It is found in the United States and Mexico. This species is harmless to humans.
Habronattus moratus is a species of jumping spider in the family Salticidae. It is found in Texas and northern Mexico.
Steatoda palomara is a species of cobweb spider in the family Theridiidae. It is found in the United States.

Neriene litigiosa, the sierra dome spider, is a species of sheet weaver spider in the family Linyphiidae. It is found in North America and has been introduced into China. This species' complex mating system has been under study since 1980 at University of Montana's Flathead Lake Biological Station by Dr. Paul J. Watson.
Yuri Mikhailovitch Marusik is a Russian arachnologist.
Heptathelidae is a family of spiders. It has been sunk within the family Liphistiidae as the subfamily Heptathelinae, but as of April 2024 was accepted by the World Spider Catalog. It is placed in suborder Mesothelae, which contains the most basal living spiders.
