Chrosiothes
Chrosiothes is a genus of comb-footed spiders in the family Theridiidae, established by Eugène Louis Simon in 1894. The genus contains 27 species distributed primarily in the New World, with most species occurring from the United States to Brazil. Males are noticeably smaller than females, with females of C. jamaicensis measuring approximately 2.9 mm compared to 1.6 mm for males. The genus is considered a senior synonym of Theridiotis.
Coleosoma
Coleosoma is a genus of comb-footed spiders in the family Theridiidae, established by O. Pickard-Cambridge in 1882. The genus comprises ten currently recognized species with a cosmopolitan distribution. Taxonomic revision has been ongoing, with several species transferred to other genera and numerous synonymies established. The genus includes both native and introduced species, with C. octomaculatum documented as established in New Zealand through anthropogenic introduction.
Neopisinus
Neopisinus is a genus of comb-footed spiders in the family Theridiidae, established in 2011 to accommodate species previously placed in other genera. The genus contains nine species distributed across the Americas, from the southern United States through Central America and the Caribbean to South America. Two species, N. fiapo and N. urucu, were described as new in the original genus description. The type species is Neopisinus fiapo.
Neospintharus
Neospintharus is a genus of comb-footed spiders in the family Theridiidae, subfamily Argyrodinae. First described by Exline in 1950, it was synonymized with Argyrodes in 1962 but revalidated in 2004. Phylogenetic studies confirm it as sister group to Rhomphaea within monophyletic Argyrodinae. The genus comprises free-living species that are not kleptoparasitic, distinguishing them from other Argyrodinae genera.
Neottiura
Neottiura Cobweb Spiders
Neottiura is a genus of comb-footed spiders (family Theridiidae) first described by Anton Menge in 1868. The genus contains six species and one subspecies distributed across Asia, Europe, North America, and North Africa. Members are small cobweb spiders that construct irregular, tangled webs. The type species, Neottiura bimaculata, has the widest distribution, spanning from North America across Eurasia to Japan.
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.
Stemmops
Stemmops is a genus of small comb-footed spiders (Theridiidae: Spintharinae) first described in 1894. The genus contains approximately 27 species, with the majority distributed in the Americas from the United States through Central America to Brazil, and a smaller number of species in East Asia including China, Japan, Korea, and Laos. One species, S. satpudaensis, has been recorded from India.
