Phryssonotus
''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.

Polyxenida
Polyxenida is an Order (biology), order of millipedes readily distinguished by a unique body plan consisting of a soft, non-calcified body ornamented with tufts of bristles. These features have inspired the common names bristly millipedes or pincushion millipedes. This order includes about 148 species in four families worldwide, which represent the only living members of the subclass Penicillata. Description Polyxenida differ from other millipedes in having a soft, non-calcified exoskeleton, unique tufts of bristles or setae, fewer legs (no more than 17 pairs), and an absence of copulatory appendages in males. Individuals are small, usually 1.5 to 4 millimeters (0.06 to 0.16 inches) long and not exceeding 7 millimeters (0.28 inches) long. Adults in most species have 13 pairs of legs, but in one species (''Lophoturus madecassus''), they have only 11 pairs of legs, and in one genus (''Phryssonotus''), they have 17 pairs of legs, except for one species (''Phryssonotus brevicape ...

Synxenidae
Synxenidae is a family of bristle millipedes (Polyxenida Polyxenida is an Order (biology), order of millipedes readily distinguished by a unique body plan consisting of a soft, non-calcified body ornamented with tufts of bristles. These features have inspired the common names bristly millipedes or p ...). Three genera and around 10 species are known. Adult synxenids possess 15 or 17 pairs of legs, with the last two pair modified for small jumps. Adults in most species in this family have 17 pairs of legs, but in two species (''Condexenus biramipalpus'' and ''Phryssonotus brevicapensis''), they have only 15 pairs of legs.
