Cybaeidae
Guides
Calymmaria californica
Calymmaria californica is a species of true spider in the family Cybaeidae. It was described by Nathan Banks in 1896. The species is found in the United States, though specific details about its biology and ecology remain poorly documented in published literature.
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.
Calymmaria suprema
Calymmaria suprema is a species of true spider in the family Cybaeidae, first described by Chamberlin and Ivie in 1937. It belongs to the genus Calymmaria, which contains 31 species north of Mexico, most restricted to the Pacific coast region. The species occurs in the United States and Canada, though specific details about its biology remain limited in published literature.
Cryphoeca montana
Cryphoeca montana is a species of true spider in the family Cybaeidae, originally described by Emerton in 1909. It is a nocturnal spider belonging to the subfamily Cryphoecinae, which was historically classified within the family Hahniidae. The species occurs in forested habitats of the United States and Canada, where it has been documented from under bark on dead trees, in leaf litter, moss, and beneath stones.
Cybaeota shastae
Cybaeota shastae is a small true spider in the family Cybaeidae, first described by Chamberlin & Ivie in 1937. It is known only from the United States, with records from the western region including California. The genus Cybaeota contains diminutive spiders closely related to Cybaeus but distinguished by genitalic and somatic characteristics. Very little is known of its biology.
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 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.
Dirksia cinctipes
Dirksia cinctipes is a species of true spider in the family Cybaeidae, described by Nathan Banks in 1896. The species has been documented across northern North America including Alaska, Canada, and the contiguous United States. Cybaeidae are wandering spiders typically associated with ground-level habitats rather than web-building.
Neocryphoeca
Neocryphoeca is a genus of small North American araneomorph spiders in the family Cybaeidae, established by V. D. Roth in 1970. It contains only two described species, both endemic to the United States: N. beattyi and N. gertschi. The genus was originally classified with funnel weavers (Agelenidae) but was reassigned to Cybaeidae in 1983 based on morphological evidence. Cybaeidae spiders are generally associated with moist microhabitats and build simple sheet webs or silk retreats.
Yorima
Yorima is a genus of araneomorph spiders in the family Cybaeidae, first described by Chamberlin & Ivie in 1942. The genus has undergone several family reassignments, originally placed in Agelenidae (funnel weavers), then Dictynidae in 1967, and finally Cybaeidae in 2017 based on revised phylogenetic understanding. It contains six described species distributed in the United States and Cuba, with most species occurring in the western United States.
Yorima angelica
Yorima angelica is a species of true spider in the family Cybaeidae, described by Roth in 1956. It is known from the United States. The genus Yorima belongs to a family of small to medium-sized spiders commonly found in leaf litter and other ground-level habitats. Information about this species is limited in the available literature.
