Parafontaria is a genus of "flat-backed" millipedes (order Polydesmida) consisting of 13 species native to Japan, where they are referred to as train millipedes.[1][2] This is because some species[vague] exhibit periodical swarming behavior during which large numbers congregate and can impact train passage when this congregation occurs on tracks. Documentation of this event goes back to 1920.[3] Individuals vary from around 3.5 to 6 cm (1.4 to 2.4 in) as adults, and feed on leaf litter as well as soil, making them comparable to earthworms in facilitating decomposition and soil nutrient cycling.[4][5]

Species

  • Parafontaria crenata Shinohara, 1986
  • Parafontaria doenitzi (Karsch, 1880)
  • Parafontaria erythrosoma (Takakuwa, 1942)
  • Parafontaria falcifera (Verhoeff, 1936)
  • Parafontaria ishiii Shinohara, 1986
  • Parafontaria laminata (Attems, 1909)[6][7] This species is poisonous.[8]
  • Parafontaria longa Shinohara, 1986
  • Parafontaria longispina Miyosi, 1951
  • Parafontaria shiraiwaensis Shinohara, 1986
  • Parafontaria terminalis (Takakuwa, 1942)
  • Parafontaria tokaiensis Tanabe, 2002
  • Parafontaria tonominea (Attems, 1899)
