Chrosiothes is a spider genus that occurs almost exclusively in the New World from the USA to Brazil, with one species found in China, Korea and Japan, and two species endemic to Taiwan.

They have two minute setae in place of a colulus, and thick legs. The males are noticeably smaller than the females: for example in C. jamaicensis the female is 2.9mm long, the male only 1.6mm.

The genera Episinus, Spintharus, Thwaitesia and Anelosimus are closely related.
