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.

Dicellophilus anomalus is a soil centipede in the family Mecistocephalidae, one of only four species in this family known from North America. First described by Ralph V. Chamberlin in 1904 from a single male specimen collected in Pacific Grove, California, this species was later transferred to the genus Dicellophilus by Filippo Silvestri in 1919. It is characterized by having exactly 41 pairs of legs in both sexes without variation, reaching up to 60 mm in body length. The species exhibits a restricted distribution along the west coast of the United States from Oregon to central California.
Gosibius intermedius
Gosibius intermedius is a centipede species in the family Lithobiidae, first described by Chamberlin in 1917. It belongs to the order Lithobiomorpha, a group commonly known as stone centipedes or lithobiomorphs. The species has been recorded from California, USA, with 36 observations documented on iNaturalist. As with other lithobiid centipedes, it is likely a predatory soil-dwelling arthropod, though specific ecological details remain poorly documented.
Scolopendra
Giant Centipedes
Scolopendra is a genus of large tropical centipedes in the family Scolopendridae, containing some of the largest living centipedes. The genus was established by Carl Linnaeus in 1758 and remains one of the most species-rich genera in the order Scolopendromorpha. Members are characterized by their substantial size, with the largest species exceeding 30 cm in length, and their potent venom delivered through modified forcipules. The genus exhibits considerable variation in coloration and size across its constituent species.
Scolopendra viridis
Florida Blue Centipede, Green Centipede
Scolopendra viridis is a medium-sized centipede in the family Scolopendridae, commonly known as the Florida Blue Centipede. It is one of 21 native North American species in the order Scolopendromorpha. The species has been documented as prey for the pygmy rattlesnake (Sistrurus miliarius), indicating its role in food webs of the southeastern United States.
Theatops
Theatops is a genus of centipedes in the family Cryptopidae, order Scolopendromorpha. Species in this genus are found in North America, southern Europe, and Asia. The genus includes Theatops posticus, a common eastern Nearctic species with a disjunct western population, and Theatops chuanensis, the first Asian record of the family. Theatops species possess distinctive morphological features including modified ultimate legs, with some species exhibiting ventral spurs on the prefemora and femora.
Thereuonema tuberculata
Japanese House Centipede
Thereuonema tuberculata is a scutigeromorph centipede in the family Scutigeridae. Native to Asia, it has been documented from China, Japan, the Korean peninsula, and Taiwan. The species has established introduced populations in North America, particularly in the eastern United States, with confirmed outdoor populations in forested and lakeside habitats in Nebraska. It is commonly confused with the related Scutigera coleoptrata in its introduced range.
Zygona duplex
Zygona duplex is a species of soil-dwelling centipede in the family Geophilidae, described by Chamberlin in 1960. It belongs to the order Geophilomorpha, which comprises the most diverse group of centipedes characterized by their elongated, worm-like bodies with numerous leg pairs. The species is known from the United States.
