Lithobius is a large genus of centipedes in the family Lithobiidae, commonly called stone centipedes, common centipedes or brown centipedes.
Pachymerium is a genus of centipedes in the family Geophilidae. Centipedes in this genus feature elongate heads, sternal pores in a pair of anterior groups and a posterior transverse band, and scattered coxal pores; the forcipular coxosternite is broad, and the ultimate article of the forcipule has a conspicuous basal denticle. These centipedes range from about 2 cm to about 8 cm in length and have 37 to 79 pairs of legs. The Chilean species Pachymerium armatum measures only 20 mm in length and has only 37 leg pairs, the minimum number observed in this genus. The Russian species P. minutum is also notable for its small size and its modest number of legs. The Portuguese species P. coiffaiti is notable for its large size and many legs. Females of the large Turkish species P. serratum can reach 78 mm in length and have as many as 79 leg pairs, the maximum number observed in this genus. This genus contains the following species:
Himantariidae is a monophyletic family of centipedes in the order Geophilomorpha and superfamily Himantarioidea, found almost exclusively in the Northern Hemisphere. Centipedes in this family feature a short head with a concave labral margin bearing a row of denticles, a single dentate lamella and some pectinate lamellae on each mandible, second maxillae with strongly tapering telopodites and slightly spatulate claws, and a stout forcipular segment with short forcipules and a wide tergite; the ultimate legs usually have no pretarsus, and the female gonopods are distinct and biarticulate.
Himantarium is a genus of centipedes in the family Himantariidae. Centipedes in this genus feature a swollen trunk that is posteriorly stout, subcircular sternal pore-fields on almost all trunk segments, much inflated coxapleura completely covered with scattered pores, and a very small metasternite on the ultimate leg-bearing segment; each mandible has a robust dentate lamella and few pectinate lamellae. These centipedes range from 10 cm to 20 cm in length, have from 87 to 179 pairs of legs, and are found in the Mediterranean region. Both the minimum and the maximum number of legs in this genus appear in the species Himantarium gabrielis, which exhibits a striking degree of intraspecific variation in leg number.
Himantarium gabrielis is a species of centipede in the family Himantariidae.
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.
Strigamia is a genus of soil centipedes in the family Linotaeniidae. 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. There are at least 50 described species in Strigamia. Centipedes in this genus can reach 15 cm in length and can have as few as 31 pairs of legs or as many as 83 leg pairs. The species S. hoffmani is notable for its small size as well as for a small number of legs. Other species with notably few legs include the Siberian species S. sibirica and the Romanian species S. lutea.
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.
Dignathodontidae is a monophyletic clade of soil centipedes in the family Geophilidae found in the Mediterranean region, extending to Macaronesia, Caucasus, and western and central Europe. The clade is characterized by a gradually anteriorly tapered body, a short head with non-attenuated antennae, and a poorly sclerotized labrum with tubercles. The number of legs in this clade varies within as well as among species and ranges from 43 pairs to 153 pairs of legs. Species in this clade tend to have more leg-bearing segments and greater intraspecific variability in this number than generally found in the family Geophilidae.
Acanthogeophilus spiniger is a species of soil centipede in the family Geophilidae found in Northwest Africa. The original description of this species is based on a male specimen measuring 27 mm in length with 71 pairs of legs. It was first assigned to the genus Geophilus, but was moved to Acanthogeophilus in 1999 by Foddai and Minelli. Like other species in its genus, it is characterized by incomplete chitin lines, complete coxopleural sutures, stout legs, and a claw-like pretarsus.
Geophilus arenarius is a species of soil centipede in the family Geophilidae found in northwest Africa, specifically near Annaba, Algeria. This species is frequently misidentified with G. electricus, and as part of the carpophagus species-complex, is closely related to both G. carpophagus and G. easoni, though it differs mainly by lacking a transverse suture on the head and peculiar integumental features (carpophagus-structures) along the trunk, as well as having relatively stouter antennae and forcipular coxosternite. G. arenarius is distinctly smaller at full growth than G. carpophagus, with usually blunter and more sclerotised tubercles lining the intermediate part of the labrum and a minute denticle at the basis of the forcipular tarsungula. It has fewer bristles lining the lateral parts of the labrum than G. easoni as well as a generally higher number of legs and a more greyish coloured trunk. The descriptions of 36 G. arenarius syntypes indicate that males of this species have 55 pairs of legs, whereas females have 55 to 59 leg pairs, with 57 as the most common number.
Geophilus impressus is a species of soil centipede in the family Geophilidae found all over Europe, and has also been recorded in North Africa. It lives frequently in endogean habitats; in Sardinia it's found mostly in Quercus ilex woods, but also in Mediterranean shrub, open habitats, and maquis. It lives anywhere from sea level to 1700 meters above it, sometimes in caves.
Geophilus bosniensis is a species of soil centipede in the family Geophilidae endemic to Bosnia and Herzegovina. It grows up to 30 millimeters and has 75 leg pairs, as well as sternites unseparated in the median but with a suture line, and sternal pore areas in the trunk segments only. Overall, the identity and phyletic position of this centipede are uncertain.
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.
Australiophilus is a genus of two species of centipedes, in the family Zelanophilidae. This genus was described by German myriapodologist Karl Wilhelm Verhoeff in 1925. Centipedes in this genus are found in Australia and New Zealand.

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.
