Harpaphe haydeniana, commonly known as the yellow-spotted millipede, almond-scented millipede or cyanide millipede, is a species of polydesmidan ("flat-backed") millipede found in the moist forests along the Pacific coast of North America, from Southeast Alaska to California. The dark coloration with contrasting yellow-tipped keels warn of its ability to exude toxic hydrogen cyanide as a defense. Despite the various common names given the species, the coloration pattern, cyanide defense, and associated almond scent occur in other flat-backed millipedes around the world.
Desmoxytes, whose species are commonly known as the dragon millipedes, is a genus of millipede of the family Paradoxosomatidae found in southeast Asia. The genus was described by Ralph Vary Chamberlin in 1923 and reviewed by Sergei Golovatch and Henrik Enghoff in 1994. At least twenty-nine species are known from southeastern China to Myanmar, Thailand, and Vietnam. One species, D. planata, has also been observed in Sri Lanka, the Andaman Islands, Seychelles, Java, Great Coco Island, and Fiji; however, this species has expanded its range by being transported through human activity. Several species have only recently been discovered and some have yet to be officially described.
