Pachymerium caucasicum is a species of centipede in Geophilidae family. It was described by Carl Attems in 1903 and is endemic to the European part of Turkey. Males of this species have 47 pairs of legs; females have 49 pairs of legs. Authorities now deem P. caucasicum to be a junior synonym of P. ferrugineum.
Himantariidae is a monophyletic family of centipedes in the order Geophilomorpha and superfamily Himantarioidea, found almost exclusively in the Northern Hemisphere. The number of leg-bearing segments in this family varies within as well as among species and ranges from 47 to 181. These centipedes are very elongated with a high mean number of trunk segments and great variability in this number within species. The maximum number of legs recorded in this family appears in the species Chomatobius bakeri. The minimum number of legs recorded in this family appears in the species Garriscaphus oreines, This family contains these genera:
Geophilus is a large, heterogeneous genus of soil centipedes in the family Geophilidae largely considered to be synonymous with Brachygeophilus. It is a mostly holarctic genus 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 range from 1 cm to 8 cm in length. 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 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.
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. The number of legs in this clade varies within species and ranges from 37 to 113 pairs of legs. Two species in this clade can have as few as 37 leg pairs, Ballophilus pallidus and Leucolinum trinidadense, and one species, Ityphilus grandis, can have as many as 113 pairs. Species in this clade tend to have more leg-bearing segments and greater intraspecific variability in this number than generally found in the family Schendylidae.
Zelanophilidae is a family of centipedes belonging to the order Geophilomorpha and superfamily Geophiloidea. Centipedes in this family are found in the Australasian region. The smallest species in this family, Tasmanophilus spenceri, measures only 23 mm in length and has only 39 pairs of legs, the minimum number recorded in this family. The largest species in this family, Australiophilus ferrugineus, can reach 120 mm in length and can have as many as 109 leg pairs. The species Australiophilus longissimus can reach 72 mm in length and can have as many as 117 leg pairs, the maximum number recorded in this family.
Steneurytion is a genus of centipedes in the family Geophilidae. It was first described by Austrian myriapodologist Carl Attems in 1909.
Geomerinus is a monotypic genus of centipedes in the family Geophilidae. It was described by French myriapodologist Henry Wilfred Brolemann in 1912. Its sole species is Geomerinus curtipes, originally described as Geophilus curtipes by Erich Haase in 1887. It is endemic to Australia.
Steneurytion morbosus is a species of centipede in the Geophilidae family. It was first described in 1877 by New Zealand naturalist Frederick Hutton.
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.
Tasmanophilus opinatus is a species of centipede in the Zelanophilidae family. It is endemic to Australia, and was first described in 1845 by British entomologist George Newport.
Australiophilus is a genus of two species of centipedes, in the family Zelanophilidae. It was described by German myriapodologist Karl Wilhelm Verhoeff in 1925.
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.
Zelanophilus is a genus of three species of centipedes, in the family Zelanophilidae. It was described by American biologist Ralph Vary Chamberlin in 1920.
Tasmanophilus spenceri is a species of centipede in the Zelanophilidae family. It is endemic to New Zealand. It was first described in 1901 by British zoologist Reginald Innes Pocock. The species epithet spenceri honours British-Australian evolutionary biologist Baldwin Spencer.
Zelanophilus provocator is a species of centipede in the Zelanophilidae family. It is endemic to New Zealand. It was first described in 1891 by British zoologist Reginald Innes Pocock. The original description of this species is based on two male specimens with 69 pairs of legs and reports a length of 59 mm, but other specimens indicate that this species can have from 67 to 77 pairs and that females can reach 75 mm in length.
Zelanophilus kapiti is a species of centipede in the Zelanophilidae family. It is endemic to New Zealand. It was first described in 1922 by New Zealand zoologist Gilbert Archey. Some authorities, including Archey himself, would later deem Z. kapiti to be a junior synonym of a similar species, Z. provocator.
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.
Maoriella australis is a species of centipede in the Geophilidae family. It is endemic to Australia. It was first described in 1936 by New Zealand zoologist Gilbert Archey. Others have since suggested that M. australis could be a junior synonym for M. macrostigma.
Marsikomerus is a genus of centipedes in the family Schendylidae. It was described by Austrian myriapodologist Carl Attems in 1938. Species in this genus are found in Mexico and in the United States.
