Aphileta misera
Aphileta misera is a species of dwarf spider in the family Linyphiidae. It has a broad distribution spanning North America, Europe, and Russia from Siberia to the Far East. As a member of the sheet-web weaving spiders, it constructs small webs in low vegetation. The species was first described by O. Pickard-Cambridge in 1882.
Carcinocephalus
Carcinocephalus is a genus of dwarf spiders (Linyphiidae: Erigoninae) characterized by distinctive cephalic modifications. These minute sheet-web building spiders are among the smallest arachnids, typically measuring only a few millimeters in length. The genus name refers to the crab-like or projecting head structure found in males. Members of this genus construct flat, sheet-like webs and are generally associated with ground-level or low vegetation habitats.
Ceratinops
Ceratinops is a genus of dwarf spiders in the family Linyphiidae, restricted to North America. First described by Nathan Banks in 1905, this genus contains small-bodied species that inhabit diverse terrestrial environments. Members of this genus are part of the sheet-web building spider fauna, though specific behavioral details remain poorly documented for most species.
Diplocentria bidentata
dwarf spider
Diplocentria bidentata is a species of dwarf spider in the family Linyphiidae, first described by Emerton in 1882. It is a small-bodied spider with a broad geographic distribution spanning the Holarctic region. The species has been recorded across North America, Europe, Russia (from European Russia to the Far East), and China. As a member of Linyphiidae, it is presumed to construct small sheet webs, though specific behavioral observations remain limited.
Emertongone
Emertongone is a monotypic genus of dwarf spiders in the family Linyphiidae. It was erected in 2022 to accommodate the species Emertongone montifer, previously classified under Oedothorax. The genus is known only from the United States. It belongs to the diverse sheet-web weaving spiders.
Emertongone montifer
Lineweaving Spider
Emertongone montifer is a dwarf spider and the sole species in the monotypic genus Emertongone. Originally described as Lophocarenum montiferum in 1882, it was later transferred to Oedothorax before being placed in its current genus in 2022 based on phylogenetic work by Lin, Lopardo & Uhl. It is a member of the sheet-web weaving family Linyphiidae and is known only from the United States.
Estrandia
Estrandia is a monotypic genus of dwarf spiders in the family Linyphiidae, containing only the species Estrandia grandaeva. First described by H. H. Blauvelt in 1936, this genus has a restricted distribution across parts of East Asia. As a member of the sheet-web weaving spiders, it shares family characteristics of small body size and web-building behavior, though specific details about its biology remain limited.
Estrandia grandaeva
Estrandia grandaeva is a small sheet-web spider in the family Linyphiidae, first described by Keyserling in 1886. It has a broad circumboreal distribution spanning northern North America, Europe, and Asia. Like other linyphiids, it constructs flat, horizontal sheet webs with a retreat area and an overlying tangle of threads to knock down prey. The species is found in cool, moist habitats across boreal and montane regions.
Floricomus
dwarf spiders
Floricomus is a genus of dwarf spiders in the family Linyphiidae, first described by C. R. Crosby and S. C. Bishop in 1925. The genus is endemic to North America, with species recorded from the United States and Canada. As of 2019, it comprises thirteen described species. These spiders belong to the sheet-web building family Linyphiidae, though specific web architectures for Floricomus species remain poorly documented.
Frontinella pyramitela
Bowl-and-doily Spider, Bowl and Doily Spider
Frontinella pyramitela, commonly known as the bowl-and-doily spider, is a small sheet-weaving spider found across North and Central America. It is distinguished by its highly characteristic web architecture: an inverted dome-shaped 'bowl' suspended above a horizontal sheet 'doily.' The species is one of the most common and widespread linyphiid spiders in North America, frequently encountered at forest edges, in pine woodlands, and in human-modified environments. Earlier taxonomic references treated this species as Frontinella communis, a name now synonymized with F. pyramitela.
Grammonota vittata
Grammonota vittata is a species of dwarf spider in the family Linyphiidae, first described by Barrows in 1919. The species is known from the United States, with additional records from several Canadian provinces including Alberta, British Columbia, and Manitoba. As a member of the sheet-web weaving spiders, it belongs to one of the most species-rich spider families. Very little is known about its specific biology or ecology.
Islandiana
dwarf spiders, money spiders
Islandiana is a genus of minute sheet-web spiders (family Linyphiidae, subfamily Erigoninae) first described by J. Braendegaard in 1932. The genus currently comprises 15 described species, with the majority distributed across North America. Several species exhibit obligate cave-dwelling habits, making the genus notable among subterranean spider faunas. The most recently described species, Islandiana lewisi, was identified in 2018 from a single cave in southern Indiana after a 30-year gap in new species descriptions for the genus.
Lepthyphantes
dwarf spiders
Lepthyphantes is a genus of dwarf spiders in the family Linyphiidae, containing 144 species and one subspecies as of October 2025. Species in this genus are found across Africa, Asia, Europe, and North America. The genus is notable for its members' adaptations to ephemeral and agricultural habitats, with documented life history strategies emphasizing high reproductive rates and dispersal capabilities.
Linyphia triangularis
Common sheetweb spider
Linyphia triangularis is a European sheet-web spider in the family Linyphiidae, first described by Carl Alexander Clerck in 1758. It is abundant throughout Europe and has been introduced to Maine, USA, where it is now established in coastal areas. The species constructs horizontal sheet-webs with 'barrage lines' above to intercept flying prey. Adults are active in late summer and autumn.
Mermessus albulus
Mermessus albulus is a species of sheet-web weaving spider in the family Linyphiidae, first described by Zorsch and Crosby in 1934. It belongs to a genus that has become notable in recent research as a model system for studying heritable bacterial symbionts and their effects on host reproduction. Related species in the genus, such as Mermessus fradeorum, host complex symbiont communities including Rickettsiella, Wolbachia, and Tisiphia, which can induce feminization in genetic males. The specific biology of M. albulus itself remains poorly documented in published literature.
Satilatlas marxi
Satilatlas marxi is a species of sheet-web weaving spider in the family Linyphiidae, described by Keyserling in 1886. It is a Holarctic species with documented occurrences in Alaska, Canada (Alberta, British Columbia, Manitoba), and South Siberia, Russia. The genus Satilatlas belongs to the diverse dwarf spider family, whose members construct horizontal sheet webs to capture prey. Very little is known about the specific biology of this species.
Soulgas
Soulgas is a monotypic genus of sheet web spiders (family Linyphiidae) endemic to the United States. It was established in 1936 by C. R. Crosby and S. C. Bishop and contains a single species, Soulgas corticarius. The genus is known from very few observations and remains poorly documented.
Spirembolus mundus
Spirembolus mundus is a species of sheet web spider (family Linyphiidae) described by Chamberlin & Ivie in 1933. It is found in the United States and Canada. The species belongs to a genus of small spiders that construct horizontal sheet webs, often with a dome or bowl shape. It was originally described as Spirembolus mundus by Chamberlin & Ivie, though some sources incorrectly cite Millidge (1980).
Tenuiphantes
Tenuiphantes is a genus of sheet-weaving spiders (family Linyphiidae) comprising 44 described species as of 2019. The genus was established by Saaristo and Tanasevitch in 1996 to accommodate species previously placed in other genera, particularly within the Lepthyphantes complex. Species occur across diverse habitats in the Northern Hemisphere and have been introduced to multiple Southern Hemisphere locations, including New Zealand, Chile, and Argentina.
