The species of Chlamydatus Curtis occurring in North America are reviewed. Chlamydatus californicus and Chlamydatus keltoni are described as new. The following synonymies are proposed: Chlamydatus arcuatus Knight and Chlamydatus auratus Kelton = Chlamydatus pulicarius (Fallén); Chlamydatus knighti Kelton = Chlamydatus schuhi Knight; and, Chlamydatus fulvipes Knight = Chlamydatus pullus (Reuter). Revised diagnoses, digital habitus illustrations, illustrations of male genitalia and legs, scanning micrographs of diagnostic features, and new distributional records are provided. A new key to the North American species is offered to facilitate identification.
