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.
The spider family Liphistiidae, recognized by Tamerlan Thorell in 1869, comprises 8 genera and about 100 species of medium-sized spiders from Southeast Asia, China, and Japan. They are among the most basal living spiders, belonging to the suborder Mesothelae. In Japan, the Kimura spider is well known.
Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of araneomorph spiders first described by Carl Jakob Sundevall in 1833. This diverse, globally distributed family includes over 3,000 species in 124 genera, and is the most common arthropod found in human dwellings throughout the world.
Linyphiidae, spiders commonly known as sheet weavers, or money spiders is a family of very small spiders comprising 4706 described species in 620 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly understood due to their small body size and wide distribution, new genera and species are still being discovered throughout the world. The newest such genus is Himalafurca from Nepal, formally described in April 2021 by Tanasevitch. Since it is so difficult to identify such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
Dictynidae is a family of cribellate, hackled band-producing spiders first described by Octavius Pickard-Cambridge in 1871. Most build irregular webs on or near the ground, creating a tangle of silken fibers among several branches or stems of one plant.
The ray spiders (Theridiosomatidae) are a family of spiders first described by Eugène Simon in 1881. They are most recognizable for their construction of cone-shaped webs.
Synaphridae is a family of spiders with thirteen described species in three genera. It was first described as a subfamily of Anapidae, but it has since been raised to family status.
Nigma is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Pekka T. Lehtinen in 1967. They have a wide distribution, including Eurasia, North America, and Northern Africa. N. walckenaeri is one of the biggest members of the Dictynidae, growing up to 5 millimetres (0.20 in) long. They are translucent green and sometimes have red or black markings on the abdomen.
Altella is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Eugène Simon in 1884.
Brommella is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Albert Tullgren in 1948.
Spermophorides is a genus of cellar spiders that was first described by J. Wunderlich in 1992.
Acartauchenius is a genus of dwarf spiders that was first described by Eugène Louis Simon in 1884.
Brasilionata is a genus of Brazilian spiders first described by Wunderlich in 1995. It is represented by a single species, B. arborense. The defining characteristics of this genus include a homogeneous color pattern on the back of the abdomen, setae on the cymbial fold the same size as other setae, a space between the anterior median eyes, and a pointed switch on the end of the palpal bulb similar to that of Microdipoena. Only two specimens have been identified, one in 1995 and another in 2015.
Dippenaaria is a genus of African araneomorph spiders in the family Anapidae, containing the single species, Dippenaaria luxurians. It was first described by J. Wunderlich in 1995, and has only been found in South Africa.
Crassignatha is a genus of Asian dwarf orb-weavers that was first described by J. Wunderlich in 1995.
Telemofila is a genus of long-legged cave spiders that was first described by J. Wunderlich in 1995. As of September 2019 it contains two species, found on Sumatra and New Caledonia: T. pecki and T. samosirensis.
Canariphantes is a genus of dwarf spiders that was first described by J. Wunderlich in 1992. It might be a junior synonym of Lepthyphantes.
Erigophantes is a monotypic genus of Indonesian dwarf spiders containing the single species, Erigophantes borneoensis. It was first described by J. Wunderlich in 1995, and has only been found on Borneo.
Bassaniodes is a genus of crab spiders that was first described by Reginald Innes Pocock in 1903.
Myanmardictyna is a genus of araneomorph spiders in the family Dictynidae, containing the single species, Myanmardictyna longifissum. It was first described by J. Wunderlich in 2017, and is only found in Myanmar.
