Geophilus Easoni
''Geophilus easoni'' is a species of soil centipede in the family Geophilidae 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. Species in ... found throughout Britain and Ireland, though its range extends through western France to at least the foothills of the Pyrenees. Until 2001, it was considered synonymous with '' G. carpophagus'', and most pre-2001 records probably refer to ''G. easoni''. It's typically shorter than ''G. carpophagus'' (up to 40 mm), with fewer leg pairs (between 47 and 51), uniform tan/chestnut coloring, and a greater size and number of coxal pores, as well as a darkly pigmented mid-piece of the labrum which bears blunt teeth. Specimens in north-western Iberia typically have a wider range of leg pairs (between 47 and 55). It nests on the ground surface under stones and dead ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ...

Geophilomorpha
The centipedes or Chilopoda are divided into the following orders. Scutigeromorpha The Scutigeromorpha are anamorphic, reaching 15 leg-bearing segments in length. Also known as house centipedes, they are very fast creatures, and able to withstand falling at great speed: they reach up to 15 body lengths per second when dropped, surviving the fall. They are the only centipede group to retain their original compound eyes, within which a crystalline layer analogous to that seen in chelicerates and insects can be observed. They also bear long and multi-segmented antennae. Adaptation to a burrowing lifestyle has led to the degeneration of compound eyes in other orders; this feature is of great use in phylogenetic analysis. The group is the sole extant representative of the Notostigmophora, defined by having a single spiracle opening at the posterior of each dorsal plate. The more derived groups bear a plurality of spiracular openings on their sides, and are termed the Pleurostigmopho ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Geophilidae
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. Species in this family are characterized by mandibles with a single pectinate lamella, slender antennae, sternal pores with variable arrangement, a generally slightly or moderately elongate head, frequently undivided coxosternite with two paramedian sclerotized lines, claws without rows of filament, and female gonopods usually being an undivided lamina. Compared to most other families in the suborder Adesmata, this family features a modest number of leg-bearing segments (no more than 125) and limited variation in this number within each species. Two species in this family include centipedes with only 29 pairs of legs: ''Geophilus persephones'' (29 pairs in the only specimen, a male), and '' G. richardi'' (29 or 31 pairs in the males and 33 pairs in ...

Geophilus Carpophagus
''Geophilus carpophagus'' is a species of soil centipede in the family Geophilidae, widely considered to be a type species of the genus ''Geophilus'' (along with '' G. electricus''). It grows up to 60 millimeters in length, with an orange/tan body bearing a distinctive purplish marbled pattern (also seen in '' Henia vesuviana''). Males of this species have 51 to 55 pairs of legs; females have 53 to 57. Taxonomy Recent studies indicate that ''G. carpophagus'' is actually a group of closely related species (dubbed the carpophagus species-complex). So far only three species have been clearly defined; ''G. carpophagus'' (Leach, 1814), '' G. easoni'' (Arthur, et al., 2001) from Europe, and '' G. arenarius'' (Meinert, 1870) from North Africa. Habitat ''Geophilus carpophagus'' is most commonly found across southeast England, though specimens have also been found in mainland Europe, North Africa, and the Canarie Islands, with a viable population discovered in Finland in 2018.
