Pseudopolydesmus

Pseudopolydesmus is a genus of flat-backed millipedes in the family Polydesmidae.

Species
Formerly, there were at least 12 described species in the genus Pseudopolydesmus. Presently however, following a review published in 2019 which used scanning electron microscopy and ultraviolet fluorescence to produce detailed images of specimens, only the following eight species are recognised:
 * Pseudopolydesmus caddo Chamberlin, 1949
 * Pseudopolydesmus canadensis (Newport, 1844)
 * Pseudopolydesmus collinus Hoffman, 1974
 * Pseudopolydesmus erasus (Loomis, 1943)
 * Pseudopolydesmus minor (Bollman, 1888)
 * Pseudopolydesmus paludicolus Hoffman, 1950
 * Pseudopolydesmus pinetorum (Bollman, 1888)
 * Pseudopolydesmus serratus (Say, 1821)
