Euagrus formosanus is a species of Taiwanese spider in the family Euagridae. [2] It was first described in 1933 from a female specimen found in the Taihoku Prefecture of Taiwan. Its Japanese name is "Taiwan-Jegogume". [1]
Adult females have a light grey hairless thorax about 1.2 centimeters long with three pairs of circular furrows. Its eyes are relatively small and all eight are white, the central four forming a trapezoid. The legs are about 1.5 centimeters long, and are a paler grey than the thorax with long black hairs. The sternum is square shaped, extending from the head to the fourth pair of legs. The abdomen is oval shaped and also grey, coated in black hairs. It has four spinnerets, the rear pair longer than the front pair at .7 centimeters. [1]
It is similar in size and color to Euagrus mexicanus, but there are two main differences. The first is a square shaped sternum rather than the oval one found in E. mexicanus. The second is that the labium only contacts the sternum, rather than inserting into it as it does in E. mexicanus. [1]

The rain beetles are a group of beetles found in the far west of North America. They spend most of their lives underground, emerging in response to rain or snow, thus the common name. Formerly classified in the Geotrupidae, they are currently assigned to their own family Pleocomidae, considered the sister group to all the remaining families of Scarabaeoidea. The family contains a single extant genus, Pleocoma, and two extinct genera, Cretocoma, described in 2002 from Late Cretaceous deposits in Mongolia, and Proteroscarabeus of Late Cretaceous China.

Archaea is an extinct genus of spiders in the family Archaeidae. As of October 2016, four species are placed in the genus. All have been found preserved in amber, either from the Baltic or Bitterfeld, Germany. First described in 1854, Archaea species have a distinctive "neck" separating the head from the thorax, and very long chelicerae ("jaws").
Dorymetaecus is a monotypic genus of Australian araneomorph spiders in the family Phrurolithidae, containing the single species, Dorymetaecus spinnipes. It was first described by William Joseph Rainbow in 1920, and has only been found on Lord Howe Island. Rainbow died in November 1919, shortly before publication of the work this species is described in.
Halonoproctidae is a family of mygalomorph spiders, split off from the family Ctenizidae in 2018. Species in the family are widely distributed in North and Central America, Australasia, Asia, southern Europe and North Africa. One species is recorded from Venezuela in South America. They are relatively large, sombrely coloured spiders, that live in burrows with some kind of trapdoor.
Exechocentrus lancearius is a species of spider in the orb-weaver spider family Araneidae, found only in Madagascar. It was initially described from a partial specimen of an adult female. The first description of a complete specimen and its prey-catching behaviour was published in 2012. E. lancearius is a bolas spider. Rather than using a web, adult females catch their prey by using a line with one or two sticky drops which they swing.
