Pachymerium is a genus of centipedes in the family Geophilidae found mainly in the west Palearctic region and in south Africa. Centipedes in this genus feature an elongate head, scattered coxal pores, and sternal pores in a pair of anterior groups and a posterior transverse band; the forcipular coxosternite is broad, and the ultimate article of the forcipule has a prominent basal denticle.
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 centipedes in the order Geophilomorpha found in the Americas, the Palearctic region, Africa, Madagascar, Australia, and southeast Asia, and also on some Pacific islands.
Strigamia is a genus of soil centipedes in the family Linotaeniidae found in temperate parts of the Holarctic region. Members of this family can be identified by their anteriorly tapering bodies, the extra claw on the forcipules, scattered coxal pores, and the distinctly swollen ultimate legs of the males. The generic name is from Latin striga, "strip," referring to its strip of bristles.
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.
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.
Zelanophilidae is a family of centipedes belonging to the order Geophilomorpha and superfamily Geophiloidea. Centipedes in this family are found in the Australasian region.
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.
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. 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.
Mecistocephalus is a genus of centipedes in the family Mecistocephalidae. It was described by British entomologist George Newport in 1843.
Schendyla is a genus of centipedes in the family Schendylidae found in the west Palearctic region. This genus 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.
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.
Ityphilus is a genus of centipedes in the clade Ballophilidae. It was described by American myriapodologist Orator Fuller Cook in 1899. Centipedes in this genus feature distinctly club-like antennae, well marked sclerotized lines on the forcipular coxosternite, and two pores on each coxopleuron. These centipedes range from about 1 cm to about 9 cm in length and have 41 to 113 pairs of legs. The dwarf species Ityphilus donatellae ranges from 8.5 to 11 mm in length and can have as few as 41 leg pairs, the minimum number found in this genus. The large species I. grandis can reach 93 mm in length and have as many as 113 leg pairs, the maximum number found in the clade Ballophilidae.
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.
Otostigminae is a large subfamily of centipedes, containing nearly half of all species in the family Scolopendridae. Members of this subfamily are abundant and widespread throughout the tropical and subtropical regions of the world, mostly in Africa, Asia, and Australia.
Schendylops ramirezi is a species of soil centipede in the family Schendylidae. This centipede is notable as the species with the fewest legs recorded in the order Geophilomorpha for each sex. This species is also the smallest in the genus Schendylops, reaching only 7 mm (0.28 in) in length.
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 among all epimorphic 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.
