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.

Boreal Yellow-headed Soil Centipede
Geophilus flavus is a soil centipede in the family Geophilidae, commonly found in terrestrial habitats including seashore locations across Europe. As a member of the Geophilomorpha, it belongs to a group of elongate, multi-legged centipedes adapted for burrowing in soil and leaf litter. The species is distinguished by its yellowish head and preference for moist coastal environments.
Geophilus oweni
Geophilus oweni is a soil centipede in the family Geophilidae, known from the central United States. It is a moderately sized geophilid, reaching up to 40 mm in length, with high numbers of leg pairs showing sexual dimorphism. The species exhibits variable yellow coloration and possesses distinctive morphological features useful for identification.
Taiyuna
Taiyuna is a genus of soil-dwelling centipedes in the family Geophilidae, established by Chamberlin in 1912. Members are elongate, multi-legged arthropods adapted to burrowing in soil and leaf litter. The genus belongs to the order Geophilomorpha, which contains the most species-rich group of centipedes. Observations are relatively sparse, with limited published natural history information available.
Taiyuna isantus
Taiyuna isantus is a species of soil centipede in the family Geophilidae, order Geophilomorpha. It was described by Chamberlin in 1909 based on specimens from the United States. Like other geophilomorph centipedes, it is likely an elongate, multi-legged arthropod adapted to burrowing in soil and leaf litter. The genus Taiyuna contains multiple species distributed in North America, but detailed biological studies of T. isantus specifically remain limited.
Taiyuna moderata
Taiyuna moderata is a soil-dwelling centipede in the family Geophilidae, first described by Chamberlin in 1941. It belongs to the order Geophilomorpha, a group characterized by elongated bodies with numerous leg pairs. The species is known from the United States, with records indicating presence in North America. Limited published information exists regarding its biology and ecology.
Zygona
Zygona is a genus of soil-dwelling centipedes in the family Geophilidae, first described by Chamberlin in 1960. Members of this genus are elongate, multi-legged arthropods characteristic of the order Geophilomorpha. The genus is poorly documented in scientific literature, with minimal published information on its species composition or biology. A single observation exists on iNaturalist, suggesting it is rarely encountered or underreported.
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.
