Microlinyphia dana
Dana Sheet-web Micro-weaver
Microlinyphia dana is a small sheetweb spider in the family Linyphiidae, commonly known as the Dana Sheet-web Micro-weaver. It constructs flat, horizontal sheet webs typically positioned close to the ground or vegetation. The species is documented from the United States and Canada, though detailed natural history information remains limited.
Microlinyphia mandibulata mandibulata
Microlinyphia mandibulata mandibulata is a subspecies of sheet-web weaving spider in the family Linyphiidae. Members of this genus are commonly known as "platform spiders" for their flat, sheet-like webs built close to the ground. Males are distinguished by a circular filament called the embolus that extends from the pedipalp. This subspecies has been documented from the United States.
Microlinyphia mandibulata punctata
Microlinyphia mandibulata punctata is a subspecies of sheet-web weaving spider in the family Linyphiidae. It was described by Chamberlin and Ivie in 1943. The genus Microlinyphia is known for the distinctive embolus structure in males—a circular filament that serves as the sperm delivery channel. Members of this genus construct flat, sheet-like webs close to the ground in grassy habitats.
Microlinyphia pusilla
Platform spider
Microlinyphia pusilla is a small sheet-web spider in the family Linyphiidae, characterized by strong sexual dimorphism and a distinctive hammock-shaped web built close to the ground in vegetation. Males actively wander in search of mates during autumn, while females and immature males remain on their webs. The species has a Holarctic distribution across North America and Eurasia.
Microneta
Microneta is a genus of dwarf spiders (family Linyphiidae) established by Anton Menge in 1869. The genus contains eleven described species distributed across North America, Europe, South America, and parts of Asia. One species, Microneta viaria, has an exceptionally broad distribution spanning multiple continents. Most species have more restricted ranges, with several endemic to specific regions such as Sweden, Peru, or Mexico.
Mythoplastoides

Mythoplastoides is a genus of dwarf spiders in the family Linyphiidae, first described by C. R. Crosby and S. C. Bishop in 1933. The genus contains two species, both restricted to the United States: M. erectus and M. exiguus (the type species). As members of Linyphiidae, these spiders are small-bodied and build sheet webs. The genus is poorly documented in scientific literature, with minimal ecological or behavioral data available.
Mythoplastoides exiguus
Mythoplastoides exiguus is a dwarf spider species in the family Linyphiidae, first described by Nathan Banks in 1892. It is known from the United States. As a member of the sheet-web weaving spiders, it belongs to one of the most species-rich spider families globally, though specific information about this particular species remains limited.

Neriene is a genus of sheet-web weaving spiders (family Linyphiidae) first described by John Blackwall in 1833. As of 2025, the genus contains approximately 62 species distributed across Africa, Asia, Europe, North America, and Greenland. These spiders construct distinctive sheet webs—horizontal platforms of silk often accompanied by a dome or bowl-shaped structure above. Species in this genus are small-bodied, with mature females typically measuring only a few millimeters. The genus has been subject to behavioral research, particularly regarding mating plug function in species such as N. emphana.

The species has an exceptionally wide geographic distribution spanning the Holarctic region, occurring across North America, Europe, North Africa, the Caucasus, Russia (from European to Far East), China, Korea, and Japan. Despite its broad range, detailed biological information remains limited. As a member of the Linyphiidae, it constructs sheet webs rather than orb webs.
Neriene digna
Neriene digna is a sheetweb spider in the family Linyphiidae, a large group commonly known as money spiders or sheetweb weavers. The species was originally described as Linyphia digna by Keyserling in 1886. It is recorded from the United States and Canada, though specific details about its biology and ecology remain poorly documented in the scientific literature. Like other members of the genus Neriene, it constructs flat sheet webs with a dome-shaped retreat.

These spiders are characterized by their small size, typically measuring only about 2 mm in total body length. Males of certain species, such as O. trilobatus, exhibit distinctive cephalothoracic modifications including tumor-like swellings or horn-like extensions. The genus has gained scientific attention due to O. gibbosus hosting up to five different bacterial endosymbionts simultaneously, representing a unique system for studying host-endosymbiont interactions.
Oreoneta
A genus of dwarf spiders (family Linyphiidae) established in 1894, comprising approximately 30 species distributed across cold-temperate and Arctic regions of the Northern Hemisphere. Most species inhabit high-latitude or high-altitude environments. The genus was revised extensively by Saaristo & Marusik in 2004, resulting in numerous new species descriptions.
