Geophilus is a large, heterogeneous genus of soil centipedes in the family Geophilidae largely considered to be synonymous with Brachygeophilus. This genus is a mostly holarctic and characterized by a claw-shaped ultimate pretarsus, anterior porefields, complete or nearly complete coxo-pleural sutures at the prosternum, and incomplete chitin-lines. Centipedes in this genus feature slightly elongate heads and labral intermediate parts with tubercles, the forcipules are usually poorly elongate with a single small tubercle at the base of each tarsungulum, and the anterior trunk metasternites usually have an anterior medial socket and a posterior transversally elongate pore-field. The generic name first appeared in Brewster's Edinburgh Encyclopaedia in 1814 as Geophilus electricus.
Tygarrup is a genus of centipedes in the family Mecistocephalidae, found mainly in southeast Asia and from the Seychelles to Hawaii. Although species in this genus can have either 43 or 45 leg-bearing segments, most of these species have 45 leg pairs. An undescribed Tygarrup species found in the Andaman Islands has 43 leg pairs. Centipedes in this genus are sometimes melanised in patches, and sternal glands are present the males of most species. These centipedes range from 2 cm to 6 cm in length. Tygarrup javanicus is one of the smallest of the mecistocephalid species and has become an invasive in greenhouses in Europe.

Diphyonyx is a genus of soil centipedes in the family Geophilidae found in the Palearctic region. They are notable for the unusually shaped claws on the anterior part of the trunk, which are swollen and have anterior spurs enlarged into elongate projections. Centipedes in this genus have a forcipular coxosternite with a pair of anterior tubercles and feature no sternal pores. Most coxal organs open into a single pit on each coxopleuron. These centipedes range from 4 cm to 6 cm in length and have 65 to 81 pairs of legs.
Sepedonophilus is a genus of three species of centipedes in the family Geophilidae. This genus is endemic to Australia, and was first described by Austrian myriapodologist Carl Attems in 1909. Centipedes in this genus feature scattered coxal pores and have no sternal pores; the lateral parts of the labrum almost touch medially, and the intermediate part is inconspicuous; the coxosternite of the second maxillae have peculiar anterior projections. These centipedes range from about 2 cm to 5 cm in length and have 49 to 79 pairs of legs. The smallest species in this genus, Sepedonophilus hodites, measures only 18 mm in length and has only 49 leg pairs, the minimum number recorded in this genus, whereas the largest species, S. perforatus, measures 50 mm in length and has 79 leg pairs, the maximum number recorded in this genus.
Steneurytion is a genus of centipedes in the family Geophilidae. It was first described by Austrian myriapodologist Carl Attems in 1909.
Queenslandophilus is a genus of centipedes in the family Geophilidae. It was described by German myriapodologist Karl Wilhelm Verhoeff in 1925. Centipedes in this genus feature second maxillae with sclerotized ridges on the coxosternite, no sternal pores, and coxopleura many scattered pores; the lateral parts of the labrum almost touch medially, and the ultimate legs most often have claws. These centipedes range from 1 cm to 6 cm in length, have 37 to 75 pairs of legs, and are found in Australia, Japan, and North America. The Japanese species Queenslandophilus monoporus and Q. macropalpus are notable for their small sizes, measuring only 10 mm and 15 mm in length, respectively. The species Q. elongatus, found in California, is notable for its large size, ranging from 40 mm to 63 mm in length. The species Q. macropalpus has only 37 leg pairs, the minimum number recorded in this genus, whereas Q. elongatus has 73 to 75 leg pairs, the maximum number recorded in this genus.
Ribautia is a genus of centipedes in the family Geophilidae. It was described by French myriapodologist Henry Wilfred Brolemann in 1909. Centipedes in this genus are found in South America, tropical Africa, Madagascar, the Arabian peninsula, Australia, New Zealand, and Melanesia.
Tasmanophilus is a genus of two species of centipedes, in the family Zelanophilidae. It was described by American biologist Ralph Vary Chamberlin in 1920. Centipedes in this genus are found in Australia and New Zealand.
Australiophilus longissimus is a species of centipede in the Zelanophilidae family. It is endemic to Australia, and was first described in 1925 by German myriapodologist Karl Wilhelm Verhoeff.
Tuoba is a genus of 17 species of centipedes, in the family Geophilidae. It was described by American biologist Ralph Vary Chamberlin in 1920.
Mecistocephalus is a genus of centipedes in the family Mecistocephalidae. It was described by British entomologist George Newport in 1843.
Orphnaeus is a genus of centipedes in the family Oryidae. This genus was described by Danish entomologist Frederik Vilhelm August Meinert in 1870. Centipedes in this genus are found in tropical regions.
Australoschendyla is a genus of centipedes in the family Schendylidae. It was described by R. E. Jones in 1996. Centipedes in this genus feature claws on the second maxillae fringed by a single row of filaments, short forcipules, subcircular sternal pore-fields, one or two pores on each coxopleuron, and ultimate legs without claws. These centipedes range from 1 cm to 2 cm in length, have 41 to 47 pairs of legs, and are found in west Australia.
Schendyla is a genus of centipedes in the family Schendylidae. It was described by Danish entomologists Vilhelm Bergsøe and Frederik Vilhelm August Meinert in 1866. Centipedes in this genus feature only a few spines on the claws of the second maxillae, two pores on each coxopleuron, and ultimate legs without claws. These centipedes range from 1 cm to about 4 cm in length and have from 31 to 57 pairs of legs. The species Schendyla verneri is notable for its small size and for having only 31 leg pairs, the minimum recorded in this genus. Other small species with notably few legs in this genus include S. walachica, S. dalmatica, S. dentata, S. gracillima. and S. armata. The species S. monoeci measures only 17.5 mm in length but can have from 51 to as many as 57 leg pairs, the maximum number found in this genus. Descriptions of the species S. vizzavonae report no more than 51 leg pairs, but this species is notable for its relatively large size, reaching 45 mm in length.
Australiophilus ferrugineus is a species of centipede in the Zelanophilidae family. It is endemic to New Zealand. It was first described in 1877 by New Zealand biologist Frederick Hutton. Since then, authorities have recognized two junior synonyms, deeming Geophilus huttoni a synonym in 1936 and Geophilus polyporus a synonym in 2014.
