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.
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
dwarf spiders
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.
Neoantistea magna
Thick-hooked Comb-tailed Spider
Neoantistea magna is a species of true spider in the family Hahniidae, a group commonly known as the sheet-web weaving spiders. It is found in the United States and Canada, with records from Alberta, British Columbia, and Manitoba. The species belongs to the marronoid clade, a genetically defined group of spiders that includes diverse ecologies and behaviors. The common name "Thick-hooked Comb-tailed Spider" refers to characteristic structures on the posterior abdomen.
