Tegenaria is a genus of fast-running funnel weavers that occupy much of the Northern Hemisphere except for Japan and Indonesia. It was first described by Pierre André Latreille in 1804, though many of its species have been moved elsewhere. The majority of these were moved to Eratigena, including the giant house spider and the hobo spider.
Cedicoides is a genus of spiders in the family Cybaeidae made up of four species. It is characterized by well developed tegulum on the bulb of the male pedipalp. When it was published by Charitonov in 1946, it acted as a subgenus to Cedicus. Later, it was argued that the differences between spiders of Cedicoides and those of other subgenera - notably the presence of a terminal apophysis and the shape of the male pedipalp - were great enough to warrant a new genus. In 2003, it was upgraded from subgenus to genus status by Marusik & Guseinov. Spiders of this genus are rare, and are often missing from spider collections taken from these regions during any time other than their mating season.

Azerithonica is a genus of Asian funnel weavers containing the single species, Azerithonica hyrcanica. It was first described by E. Guseinov, Yuri M. Marusik & S. Koponen in 2005, and has only been found in Azerbaijan.
Cepheia is a monotypic genus of European araneomorph spiders in the family Synaphridae containing the single species, Cepheia longiseta. It was first described as Theonoe longiseta in 1881, and was moved to its own genus in 1894. Originally placed with the tangle-web spiders, it was moved several times before settling in the Synaphridae in 2003. Paolo Brignoli noted that it is an unidentifiable theridiid.
Synaphris is a genus of araneomorph spiders in the family Synaphridae, and was first described by Eugène Louis Simon in 1894. Originally placed with the tangle web spiders, it was moved to the Symphytognathidae in 1973, and to the Synaphridae in 2003.
Raveniola is a genus of spiders in the family Nemesiidae, first described in 1987 by Zonstein.
Chalcoscirtus lepidus is a species of jumping spider in the genus Chalcoscirtus that has been found in Afghanistan, Iran, Tajikistan,Turkmenistan and Uzbekistan. The spider was first described in 1996 by Wanda Wesołowska, although the first male was identified three years later. The spider is small, with a carapace between 1.06 and 1.2 mm long and an abdomen between 1.03 and 2.2 mm long. The female is larger and lighter than the male and has three narrower stripes on the back while the male has a large scutum. In both cases, the carapace is plain. The scutum and lack of pattern on the carapace help distinguish the spider from related species. It can also be identified by its copulatory organs, particularly the long curved embolus on the male and the position of the copulatory openings on the female epigyne, which differ from the otherwise similar Chalcoscirtus infimus.
Caviphantes is a genus of dwarf spiders that was first described by R. Oi in 1960.
