Pachymerium syriacum is a species of centipede in the family Geophilidae that is endemic to the Dodecanese Islands. The original description of this species is based on a female specimen measuring 110 mm in length with 87 pairs of legs. More recently, authorities have assigned this species to another genus under the name Gnathoribautia syriaca.
The Geophilidae are a polyphyletic, cosmopolitan family of soil centipedes in the superfamily Geophiloidea containing the mostly defunct clades Aphilodontidae, Dignathodontidae, Linotaeniidae, Chilenophilinae, and Macronicophilidae.
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.
Schendylidae is a family of centipedes in the order Geophilomorpha.
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.
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.
Pachymerinus is a genus of centipedes in the family Geophilidae. It was described by Italian entomologist Filippo Silvestri in 1905. Centipedes in this genus feature elongate heads, elongate forcipules with denticles, scattered coxal pores, and few sternal pores, if any; the intermediate part of the labrum is narrow and has no denticles. These centipedes range from about 3 cm to 8 cm in length, have 47 to 81 pairs of legs, and are found in Chile and southeast Australia. The Australian species Pachymerinus froggatti is notable for its relatively small size, measuring only 28 mm in length. The larger Chilean species P. porteri measures 46 mm in length but can have as few as 47 leg pairs, the minimum number recorded in this genus. The Chilean species P. pluripes measures only 32 mm in length but can have 79 or 81 leg pairs, the maximum number recorded in this genus. The Chilean species P. canaliculatus is known from a female specimen with 75 leg pairs and is notable for its large size, measuring 75 mm in length.
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.
Pachymerellus zygethus is a species of centipede in the Geophilidae family. It is endemic to Australia and New Zealand, and was first described in 1920 by American biologist Ralph Vary Chamberlin.
Tuoba is a genus of 17 species of centipedes, in the family Geophilidae. It was described by American biologist Ralph Vary Chamberlin in 1920.
Zelanophilus is a genus of three species of centipedes, in the family Zelanophilidae. This genus was described by American biologist Ralph Vary Chamberlin in 1920. Centipedes in this genus are found in Australia and New Zealand.
Mecistocephalus is a genus of centipedes in the family Mecistocephalidae. It was described by British entomologist George Newport in 1843.
