Attidops
Attidops is a genus of diminutive jumping spiders (Salticidae) established by Nathan Banks in 1905. The genus contains four described species distributed across North America from Canada to Mexico. These spiders measure only 2–3 mm in body length and exhibit minimal sexual dimorphism. The genus name derives from the salticid suffix -attus and Greek -ops ("to look like"), referencing its resemblance to related genera.
Eilica
Eilica is a genus of ground spiders in the family Gnaphosidae, established by Eugen von Keyserling in 1891. The genus comprises 28 species with worldwide distribution, though South America hosts 10 species including several with meridional distributions. Members are small to medium-sized spiders ranging from 2.2–7.8 mm in length. They are distinguished by distinctive cheliceral morphology including two or three translucent laminae on the cheliceral retromargin and anteriorly produced chelicerae with convergent endites.
Phoroncidia
Mushroom Comb-footed Spiders, cob-web spiders
Phoroncidia is a genus of comb-footed spiders in the family Theridiidae, first described by J. O. Westwood in 1835. The genus contains approximately 83 species distributed worldwide. Members are characterized by heavily sclerotized, often leathery abdomens with distinctive sculpturing including folds, humps, spines, or tubercles. They are commonly known as Mushroom Comb-footed Spiders.
Spirembolus
Spirembolus is a genus of sheet web spiders in the family Linyphiidae, first described by Ralph Vary Chamberlin in 1920. The genus contains 41 species distributed across North America, with records from the United States, Canada, and Mexico. These spiders are small-bodied web-builders characteristic of the sheet weaver guild. The genus has been subject to taxonomic revision, with many species described by A.F. Millidge in 1980.
Urozelotes
Urozelotes is a genus of ground spiders in the family Gnaphosidae, first described by Mello-Leitão in 1938. The genus comprises six species as of 2025. These small spiders are characterized by their oval carapace with distinctive setation and uniform pale orange coloration.
