Pseudonemesia kochalkai is a species of spider in the family Microstigmatidae. It was first described by Robert J. Raven & Norman I. Platnickin 1981. It is found in Colombia.
The Mygalomorphae, or mygalomorphs, are an infraorder of spiders, and comprise one of three major groups of living spiders with over 3000 species, found on all continents except Antarctica. Many members are known as trapdoor spiders due to their creation of trapdoors over their burrows. Other prominent groups include Australian funnel web spiders and tarantulas, with the latter accounting for around one third of all mygalomorphs.
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.
Atracidae is a family of mygalomorph spiders, commonly known as Australian funnel-web spiders or atracids. It has been included as a subfamily of the Hexathelidae, but is now recognized as a separate family. All members of the family are native to Australia. Atracidae consists of three genera: Atrax, Hadronyche, and Illawarra, comprising 35 species. Some members of the family produce venom that is dangerous to humans, and bites by spiders of six of the species have caused severe injuries to victims. The bites of the Sydney funnel-web spider and northern tree-dwelling funnel-web spider are potentially deadly, but no fatalities have occurred since the introduction of modern first-aid techniques and antivenom.
Nursery web spiders (Pisauridae) is a family of araneomorph spiders first described by Eugène Simon in 1890. They resemble wolf spiders (Lycosidae) except for several key differences. Wolf spiders have two very prominent eyes in addition to the other six, while a nursery web spider's eyes are all about the same size. Additionally, female nursery web spiders carry their egg sacs with their jaws and pedipalps instead of attaching them to their spinnerets as wolf spiders do. When the eggs are about to hatch, a female spider builds a nursery "tent", places her egg sac inside, and stands guard outside, hence the family's common name. Like the wolf spiders, however, the nursery web spiders are roaming hunters that don't use webs for catching prey.
Hexathelidae is a family of mygalomorph spiders. It is one of a number of families and genera of spiders known as funnel-web spiders. In 2018, the family was substantially reduced in size by genera being moved to three separate families: Atracidae, Macrothelidae and Porrhothelidae. Atracidae includes the most venomous species formerly placed in Hexathelidae.
Zoropsidae, also known as false wolf spiders for their physical similarity to wolf spiders, is a family of cribellate araneomorph spiders first described by Philipp Bertkau in 1882. They can be distinguished from wolf spiders by their two rows of eyes that are more equal in size than those of Lycosidae.
Spider Widow is a fictional superhero character that was published by Quality Comics during the Golden Age of Comic Books. The character was created by writer and artist Frank Borth, and debuted in Feature Comics #57, which bore a cover date of June 1942. Borth continued to write and draw the Spider Widow feature until the end of its run in Feature Comics #72.
Microstigmatidae is a small family of spiders with about 25 described species in eight genera. They are small ground-dwelling and free-living spiders that make little use of silk.
Nemesiidae, also known as funnel-web trapdoor spiders, is a family of mygalomorph spiders first described by Eugène Simon in 1889, and raised to family status in 1985. Before becoming its own family, it was considered part of "Dipluridae".
Barychelidae, also known as brushed trapdoor spiders, is a spider family with about 300 species in 42 genera.
Palpimanidae, also known as palp-footed spiders, is a family of araneomorph spiders first described by Tamerlan Thorell in 1890. They are widely distributed throughout the tropical and subtropical regions of the world, the Mediterranean and one in Uzbekistan, but not Australia. They are not common and there is a high degree of endemism.
Lygromma is a spider genus of Central and South America. There are species with eight, six and no eyes. The eyeless L. anops is endemic to Galapagos, while the not closely related blind L. gertschi is found only on Jamaica.
Robert John Raven is an Australian arachnologist, being the Head of Terrestrial Biodiversity and the Senior Curator (Arachnida) at the Queensland Museum. Dr Raven has described many species of spider in Australia and elsewhere, and is spider bite consultant to the Royal Brisbane Hospital, leading to much work on spider toxins.
Caledothele is a genus of South Pacific spiders in the family Euagridae. It was first described by Robert Raven in 1991.
Pseudonemesia parva is a species of spider in the family Microstigmatidae. It was described by Caporiacco (1955) in Venezuela.
Pseudonemesia is a genus of spiders in the family Microstigmatidae, found in Colombia and Venezuela.
Striamea is a genus of South American curtain web spiders that was first described by Robert Raven in 1981. As of May 2019 it contains only two species, both found in Colombia: S. gertschi and S. magna.
Semidysderina is a genus of spiders in the family Oonopidae. It was first described in 2011 by Platnick & Dupérré. As of 2017, it contains 6 species, all found in Colombia.
Zimiromus is a genus of ground spiders that was first described by Nathan Banks in 1914.
