Badumna
House Spiders, Black House Spider, Grey House Spider
Badumna is a genus of medium to large cribellate spiders in the family Desidae, first described by Tamerlan Thorell in 1890. The genus is native to the Indo-Australian region, with most species endemic to Australasia. Several species, particularly B. longinqua and B. insignis, have become synanthropic and have been introduced to multiple continents, establishing populations in urban environments. The most well-known species, B. insignis, is commonly called the 'black house spider' and has been documented in Japan as an introduced species.
Calymmaria persica
Calymmaria persica is a species of true spider in the family Cybaeidae, found in the United States. It belongs to the marronoid clade, a diverse group of small to medium-sized spiders united by genetic rather than obvious morphological characteristics. The species constructs distinctive basket-shaped webs and is primarily nocturnal.
Cicurina tersa
Cicurina tersa is a species of true spider in the family Cicurinidae, a family recently elevated from subfamily status within the marronoid spider clade. The species was described by Eugène Simon in 1886 and is known from the United States and Canada. Like other members of its genus, C. tersa is a small, generally cryptically colored spider.
Cybaeus
Soft Spiders
Cybaeus is a genus of araneomorph spiders in the family Cybaeidae, first described by Ludwig Carl Christian Koch in 1868. The genus contains approximately 198 species distributed across America, Europe, Japan, Korea, and China. North American species are classified into Holarctic and Californian clades, with many exhibiting restricted geographic ranges and conservation concerns. Females of different species are difficult to distinguish, particularly in North America; species identification relies heavily on examination of male pedipalps.
Cybaeus eutypus
Owl Woodland Spider
Cybaeus eutypus is a species of true spider in the family Cybaeidae, commonly known as the Owl Woodland Spider. It is found in the United States and Canada. The species was described by Chamberlin and Ivie in 1932. Like other members of the genus Cybaeus, it belongs to the marronoid clade of spiders, a group that has been subject to recent phylogenetic revision.
Cybaeus morosus
Morose Woodland Spider
Cybaeus morosus is a small woodland spider in the family Cybaeidae, first described by Eugène Simon in 1886. It belongs to the 'marronoid' clade, a group of spiders united by molecular phylogenetics rather than obvious morphological similarities. The species is known from forest floor habitats in North America, where it constructs sheet webs or retreats under debris. Like other Cybaeidae, it is a ground-dwelling spider that plays a role in leaf litter decomposition and nutrient cycling.
Cybaeus reticulatus
Common West Coast Woodland Spider
Cybaeus reticulatus is a species of true spider in the family Cybaeidae. It was first described by French arachnologist Eugène Simon in 1886. The species is found in the United States and Canada, with observations concentrated on the West Coast. It belongs to the marronoid clade, a group of spiders united by molecular phylogenetics rather than obvious morphological synapomorphies.
Cybaeus signifer
Night-hunting Woodland Spider
Cybaeus signifer is a species of true spider in the family Cybaeidae, described by Eugène Simon in 1886. It is distributed across the United States and Canada. The species belongs to the marronoid group of spiders, a diverse clade that has been subject to recent phylogenetic revision using genetic data from museum specimens.
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.
Nigma
Nigma is a genus of cribellate araneomorph spiders in the family Dictynidae, established by Pekka T. Lehtinen in 1967. The genus contains approximately fourteen species distributed across Eurasia, North America, and Northern Africa. Members are generally small, with N. walckenaeri being among the largest in the family at up to 5 mm body length. The genus is part of the marronoid spider group, which has been subject to recent phylogenetic revision using genetic data from museum specimens.
