• Arctogeophilus

  Arctogeophilus is a genus of soil centipedes in the family Geophilidae, comprising fourteen species distributed across subarctic and temperate regions of Asia, North America, and western Europe. First described as a subgenus by Carl Attems in 1909 and elevated to genus rank by Henri Ribaut in 1910, its name references the northern distribution toward Ursa Major. Species range from 11 mm to 50 mm in length and possess 35 to 69 pairs of legs.
