Geophilus is a large, heterogeneous genus of soil centipedes in the family Geophilidae largely considered to be synonymous with Brachygeophilus. The generic name first appeared in Brewster's Edinburgh Encyclopaedia in 1814 as Geophilus electricus. This genus has a Holarctic distribution.
Schendylidae is a family of soil centipedes in the superfamily Himantarioidea and the order Geophilomorpha. These centipedes are found in the Americas, the Palearctic region, Africa, Madagascar, Australia, and southeast Asia, and also on some Pacific islands. This family was first proposed by the American biologist Orator F. Cook in 1896.
Ballophilidae is a monophyletic group of centipedes belonging to the order Geophilomorpha and superfamily Himantarioidea. Authorities now dismiss this group as a family, citing phylogenetic analysis, and instead refer to this clade as Ballophilinae, a possible subfamily within the family Schendylidae. Centipedes in this clade differ from others in the family Schendylidae by having bodies tapered toward the anterior tip, short heads, slender forcipules that are well apart, and an undivided lamina for the female gonopods. Centipedes in this clade are found in most tropical regions.
Queenslandophilus is a genus of soil centipedes in the family Geophilidae. This genus was described by German myriapodologist Karl Wilhelm Verhoeff in 1925. These centipedes are found in Australia, Japan, and North America.
Ribautia is a genus of centipedes in the family Geophilidae. This genus 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.
Tuoba is a genus of 17 species of centipedes, in the family Geophilidae. This genus was described by American biologist Ralph Vary Chamberlin in 1920. These centipedes are found in coastal regions and islands in the Mediterranean and in the Atlantic, Pacific, and Indian oceans.
Schendyla is a genus of soil centipedes in the family Schendylidae. These centipedes are found in the west Palearctic region. This genus was described by Danish entomologists Vilhelm Bergsøe and Frederik Vilhelm August Meinert in 1866. This genus now includes more than 20 species.
Maoriella is a genus of centipedes in the family Geophilidae. It was described by Austrian myriapodologist Carl Attems in 1903. Species in this genus are found in New Zealand, Australia, and Tahiti.
Pectiniunguis is a genus of centipedes in the family Schendylidae. This genus was described by American naturalist Charles Harvey Bollman in 1889. Centipedes in this genus feature second maxillae with claws fringed by two rows of filaments, transversally elliptical sternal pore-fields on almost all trunk segments, two pores on each coxopleuron, and ultimate legs without claws.
Nesomerium is a monotypic genus of centipedes in the family Geophilidae. It was described in 1953 by American myriapodologist Ralph Vary Chamberlin. The sole species is Nesomerium hawaiiense Chamberlin, 1953. Since the original description of this species based on a single specimen, no other specimens have been referred to this species or this genus, and some authorities express doubts about the validity of these taxa and their placement in the family Geophilidae.
Schendylops is the largest genus of centipedes in the family Schendylidae, containing more than 60 species. This genus was first proposed by the American biologist Orator F. Cook in 1899 for the type species originally named Schendyla grandidieri in 1897. Most species in this genus are found in the Neotropical region, but a dozen species are found in Africa and Madagascar. These species live in diverse habitats, ranging from sea level to high altitudes, e.g., at 4,500 m (14,800 ft) above sea level in the Andes mountains.
Dinogeophilus is a genus of soil centipedes in the family Schendylidae. This genus contains only two species, Dinogeophilus pauropus and D. oligopodus, which range from 4.5 to 5.5 mm in length. These species are notable as the smallest not only in the order Geophilomorpha but also in any epimorphic order of centipedes. The species D. oligopodus is also notable as one of only six species of soil centipedes to feature only 29 pairs of legs and one of only two species to include females with only 29 pairs, the minimum number recorded for females in the order Geophilomorpha.
Dinogeophilus oligopodus is a species of soil centipede in the family Schendylidae. This centipede ranges from 4.5 to 5.5 mm in length, the smallest size recorded not only in the order Geophilomorpha but also in any epimorphic order of centipedes. This species is also notable as one of only six species in the order Geophilomorpha to feature only 29 pairs of legs and one of only two species to include females with only 29 pairs, the minimum number recorded for females in this order.
Arctogeophilus is a genus of soil centipedes in the family Geophildae. These centipedes are found in subarctic and temperate regions of Asia, North America, and western Europe. The taxon Arctogeophilus was first proposed in 1909 by the Austrian myriapodologist Carl Attems as a subgenus within the genus Geophilus. The French zoologist Henri Ribaut elevated Arctogeophilus to the rank of genus in 1910.
Arctogeophilus glacialis is a species of soil centipede in the family Geophildae. This centipede is found in Russia, Alaska, and Canada. This species was first described in 1909 by the Austrian myriapodologist Carl Attems as the type species for the taxon Arctogeophilus, which was originally described as a subgenus of the genus Geophilus but was elevated to the status of genus in 1910 by the French zoologist Henri Ribaut.
Escaryus is a genus of soil centipedes in the family Schendylidae. These centipedes are notable as schendylids adapted to colder temperatures and restricted to cool climates and high latitudes. With more than 30 species, this genus is easily the largest group of such centipedes in the family Schendylidae. Most schendylids are limited to tropical or subtropical regions.
Alloschizotaenia is a genus of soil centipedes in the family Geophilidae. This genus contains only three valid species. Centipedes in this genus are found in central and east Africa.
Escaryus kirgizicus is a species of soil centipede in the family Schendylidae. As the species name suggests, this centipede is found in Kyrgyzstan. This species is known only from high mountains and is notable for being found at one of the highest altitudes recorded for any centipede in the order Geophilomorpha in Central Asia.
Mecistocephalus nannocornis is a species of soil centipede in the Mecistocephalidae family. This centipede has only 45 pairs of legs, the minimum number recorded in the genus Mecistocephalus. This centipede was the second species in this genus to be discovered with such a modest number of legs.
Mesoschendyla is a genus of soil centipedes in the family Schendylidae. These centipedes are found in Africa, Madagascar, and Java. The Austrian myriapodologist Carl Attems originally proposed Mesoschendyla in 1909 as a subgenus within the genus Schendyla. The genus Mesochendyla is relatively small, containing only eight species. These centipedes resemble their close relatives in the genera Schendylops and Orygmadyla.
