Pachymerium antipai is a species of centipede in the Geophilidae family found in Romania. 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 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.
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.
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.
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 aetnensis is a species of soil centipede in the family Geophilidae found in Europe and northern Asia, excluding China. As described by Verhoeff in 1928, it grows up to 28 millimeters and has 53 leg pairs, 4 sensory setae each on the 2nd-4th front sternites, slightly notched maxillae, and very faint sternal pits on the thorax as well as poorly developed sternal grooves.
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.
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 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.
Mecistocephalus tahitiensis is a species of centipede in the Mecistocephalidae family. It was described in 1862 by American myriapodologist Horatio Wood.
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.
Eucratonyx is a genus of centipedes in the family Gonibregmatidae. This genus was described in 1898 by British zoologist Reginald Innes Pocock. Centipedes in this genus are found from the Andaman Islands to New Britain.
Mecistocephalus uncifer is a species of centipede in the Mecistocephalidae family. It was described in 1919 by Italian myriapodologist Filippo Silvestri. This species has 49 pairs of legs and can reach 65 mm in length.
