Motyxia is a genus of cyanide-producing millipedes (collectively known as Sierra luminous millipedes or motyxias) that are endemic to the southern Sierra Nevada, Tehachapi, and Santa Monica mountain ranges of California. Motyxias are blind and produce the poison cyanide, like all members of the Polydesmida. All species have the ability to glow brightly: some of the few known instances of bioluminescence in millipedes.

Apheloria is a genus of flat-backed millipedes in the tribe Apheloriini within the family Xystodesmidae. These millipedes are found in the central and northeastern regions of the United States, but the distribution of this genus extends as far north as southern Quebec in Canada. Like all millipedes in the tribe Apheloriini, all species of Apheloria produce cyanide, which they emit through their ozopores as a defense against predators. Species of Apheloria are also known as cherry millipedes, because the production of cyanide also generates benzaldehyde, which smells like cherries or almonds.

Oxidus is a genus of flat-backed millipedes in the family Paradoxosomatidae. There are about nine described species in Oxidus. thumb|Oxidus gracilis
