The genus Speorthus Chamberlin is revalidated for S. tuganbius Chamberlin and S. reyesi, new species (Diplopoda, Polydesmida, Macrosternodesmidae). The families Polydesmidae and Macrosternodesmidae (as they occur in North America) are briefly discussed, and their component North American genera listed. The validity of Macrosternodesmidae is reaffirmed; the family is predominantly North American. Nearctodesminae, new status, is formally designated as a subfamily of Macrosternodesmidae. The superfamily Trichopolydesmoidea is synonymized with the superfamily Polydesmoidea, new combination.
