Pachymerium antipai is a species of centipede in the Geophilidae family found in Romania. This species is yellow-brown and can reach 30 mm in length. A review of the original description of this species suggests that P. antipai may be a junior synonym of P. ferrugineum.
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.
Pachymerium syriacum is a species of centipede in the family Geophilidae. The original description of this species is based on a female specimen measuring 110 mm in length with 87 pairs of legs. Authorities now place this species in another genus under the name Gnathoribautia syriaca, a species found in Turkey, Greece, and Lebanon.
Pachymerium tabacarui is a species of centipede in Geophilidae family that is endemic to Romania. The original description of this species is based on a female specimen from the Carpathians measuring 15 mm in length with 53 pairs of legs. Some authorities consider this description consistent with a juvenile specimen of P. ferrugineum and therefore deem P. tabacarui to be a junior synonym of that species. A more recent review of this description suggests that P. tabacarui is a junior synonym of Geophilus flavus rather than P. ferrugineum. Extensive investigations in the Carpathian region have failed to collect any more specimens.
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.
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. These centipedes are found almost worldwide.
Mecistocephalidae is a monophyletic family of centipedes in the order Geophilomorpha. It is the only family in the suborder Placodesmata. Most species in this family live in tropical or subtropical regions, but some occur in temperate regions. This family is the third most diverse in the order Geophiliomorpha, with about 170 species, including about 130 species in the genus Mecistocephalus.
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.
Linotaeniidae are a monophyletic clade of soil centipedes in the family Geophilidae found mostly in the temperate regions of the Holarctic as well as the south Andes. Species in the clade Linotaeniidae are characterized by a body that usually tapers toward the anterior tip; mandibles with a single pectinate lamella; second maxillae with coxo-sternite usually undivided and claws without projections; forcipular segment short, with tergite remarkably wide, forcipules evidently tapering; coxal organs opening through distinct pores on the ventral surface of the coxo-pleura. The number of legs in this clade varies within as well as among species and ranges from as few as 31 pairs of legs to as many as 83 leg pairs. Compared to most families in the suborder Adesmata, this clade features a modest number of leg-bearing segments and limited variation in this number within each species.
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.
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.
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 pusillus is a species of soil centipede in the family Geophilidae found in Algeria. It grows up to 11 millimeters in length. The original description of this species is based on ten specimens: five male specimens from Algeria with 31 pairs of legs, and five specimens from Germany. Records from the Alpstein mountains indicate that G. pusillus is a soil-dwelling species that prefers humus-rich soil, but these records deserve confirmation. Some authorities consider the specimens recorded from Europe to be specimens of G. ribauti that have been misidentified as specimens of the Algerian species G. pusillus.
Geophilus bobolianus is a species of soil centipede in the family Geophilidae found in France and Italy. This species has 45 to 51 pairs of legs. It was originally classified as a subspecies of G. longicornis identified by its lack of anterior sternal pores.
Strigamia crassipes is a centipede belonging to the family Linotaeniidae in the order Geophilomorpha.
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.
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 or with only rudimentary claws.
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.
Mecophilus is a genus of soil centipedes in the subfamily Aphilodontinae, a clade formerly known as the family Aphilodontidae but now deemed a subfamily within the family Geophilidae. The species in this genus are among the smallest centipedes in the order Geophilomorpha, reaching only 8 mm in length. This genus is also notable for featuring the fewest legs in the subfamily Aphilodontinae. The species in this genus are found in the Atlantic Forest in south and southeastern Brazil.
