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.
Geophilus is a large, heterogeneous genus of soil centipedes in the family Geophilidae largely considered to be synonymous with Brachygeophilus. This genus is mostly Holarctic and characterized by a claw-shaped ultimate pretarsus, 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.
Aphilodontidae is a monophyletic clade of soil centipedes in the family Geophilidae found in South America and South Africa. These centipedes are closely related to Geoperingueyia and characterized by shieldlike setae on the front of the head, lateral parts of the flattened cuticle above the mouthparts, and combined forcipular trochanteroprefemur and femur. The number of legs in this clade varies within species as well as among species and ranges from as few as 33 pairs of legs to as many as 93 pairs. The three species in the Brazilian genus Mecophilus have the fewest legs and smallest size in this clade. The two species with the fewest legs in the Neotropical genus Aphilodon also feature notably modest numbers with limited variation recorded: A. meganae and A. indespectus. Aphilodon meganae is also notable for its small size, the smallest in its genus. Species with more legs also exhibit greater variation in the number of leg pairs. The largest species in this clade (A. micronyx and A. pereirai) can reach 70 mm in length.
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 gavoyi is a species of soil centipede in the family Geophilidae. It is closely related to both Geophilus aetnensis and its junior synonym G. evisensis; it's considered by some to be a synonym of G. evisensis. It's found under stones in northern Asia and western Europe, especially France and England. It grows to between 23 and 35 millimeters in length and has between 39 and 43 leg pairs in males and 41–45 in females. In the since debunked elongata subspecies it was said to vary from between 49 and 55 leg pairs in males and between 51 and 57 in females. As described in 1964, it has well-developed sternal grooves, longer legs than G. aetnensis, and normal claws in the anal legs.
Geophilus osquidatum is a species of soil centipede in the family Geophilidae found in western Europe, from mainland Spain through western France to Britain and Ireland, though it's also been recorded in Italy, Czech Republic, and Germany. Males of this species have 51 to 57 pairs of legs; females have 53 to 63 leg pairs. This species grows up to 30 millimeters and is bright yellow with a darker reddish head. Because of this, it's often confused with G. flavus and G. gracilis. Its subspecies, G. osquidatum porosum, was found synonymous with G. flavus. In Britain, G. osquidatum is found in a wide range of habitats including woodland, grassland, and coastal shingle as well as gardens and waste ground.
Geophilus punicus is a species of soil centipede in the family Geophilidae found in the Western Mediterranean, specifically Italy and North Africa (Tunisia). It's an epigeic species, though its habitat preferences are unknown apart from one record from caves, indicating it may also be a trogloxene. The original description of this species is based on male specimens with 43 pairs of legs.
Geophilus erzurumensis is a species of soil centipede in the family Geophilidae found only in Erzurum, Turkey, which it is named after.
Steneurytion morbosus is a species of centipede in the Geophilidae family. This species was first described in 1877 by New Zealand naturalist Frederick Hutton. Authorities would later deem Pachymeroides alter, Zelanion paucipes, and Zelanion similis to be junior synonyms. Some authorities do not include this species in the genus Steneurytion.
Tuoba laticeps is a species of centipede in the Geophilidae family. It is endemic to Australia, and was first described in 1891 by British zoologist Reginald Innes Pocock.
Zelanophilus pococki is a species of centipede in the Zelanophilidae family. It was first described in 1963 by R.E. Crabill.
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 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.
Maoriella ecdema is a species of centipede in the Geophilidae family. It is endemic to New Zealand. It was first described in 1964 by American zoologist Ralph Crabill.
Maoriella zelanica is a species of centipede in the Geophilidae family. It is endemic to New Zealand. It was first described in 1920 by American biologist Ralph Vary Chamberlin.
