Phryssonotus is a genus of bristle millipedes containing around nine extant species. Species are characterized by the possession of dark, rear-projecting scale-shaped bristles (trichomes) on the tergites; all other bristles are long and hairlike. Adults in this genus have 17 pairs of legs, except for the species Phryssonotus brevicapensis, in which they have only 15 pairs of legs.
