Chrosiothes is a genus of comb-footed spiders that was first described by Eugène Louis Simon in 1894.[3] It is considered a senior synonym of Theridiotis.[2]

They have thick legs and two minute setae in place of a colulus. Males are noticeably smaller than females. Females of C. jamaicensis are about 2.9 millimetres (0.11 in) long, while males are only about 1.6 millimetres (0.063 in).

They are closely related to members of Episinus, Spintharus, Thwaitesia and Anelosimus.
Species

As of May 2020 it contains twenty-seven species that occurs almost exclusively in the New World from the United States to Brazil, with one species found in China, Korea and Japan, and two species endemic to Taiwan:[1]
