Geophilus Arenarius
''Geophilus arenarius'' is a species of soil centipede in the family Geophilidae found in northwest Africa, specifically near Annaba, Algeria. It's frequently misidentified with '' G. electricus'', and as part of the carpophagus species-complex it's 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 Sclerotin is a component of the cuticle of various Arthropoda, most familiarly insects. It is formed by cross-linking members of particular classes of protein molecules, a biochemical process called sclerotization, a form of tanning in which qui ... tubercles lining the intermediate part of the labrum and a minute denticle at the bas ...

Frederik Vilhelm August Meinert
Frederik Vilhelm August Meinert (1833, in Copenhagen – 1912), was a Danish people, Danish entomologist and editor of the first series of ''Entomologiske Meddelelser''. Meinert initially studied theology . Later he was a pupil of Jørgen Matthias Christian Schiødte and he too became ''Inspektor'' at the University of Copenhagen Zoological Museum, Zoological Museum in Copenhagen.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Maghreb
The Maghreb (; ar, الْمَغْرِب, al-Maghrib, lit=the west), also known as the Arab Maghreb ( ar, المغرب العربي) and Northwest Africa, is the western part of North Africa and the Arab world. The region includes Algeria, Libya, Mauritania (also considered part of West Africa), Morocco, and Tunisia. The Maghreb also includes the disputed territory of Western Sahara (controlled mostly by Morocco and partly by the Sahrawi Arab Democratic Republic) and the Spanish cities Ceuta and Melilla.Article 143. As of 2018, the region had a population of over 100 million people. Through the 18th and 19th centuries, English sources often referred to the region as the Barbary Coast or the Barbary States, a term derived from the demonym of the Berbers. Sometimes, the region is referred to as the Land of the Atlas, referring to the Atlas Mountains, which are located within it. The Maghreb is usually defined as encompassing much of the northern part of Africa, including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annaba
Annaba ( ar, عنّابة, "Place of the Jujubes"; ber, Aânavaen), formerly known as Bon, Bona and Bône, is a seaport city in the northeastern corner of Algeria, close to the border with Tunisia. Annaba is near the small Seybouse River and is in the Annaba Province. With a population of about 464,740 (2019) and 1,000,000 for the metropole, Annaba is the third-largest city and the leading industrial center in Algeria. Annaba is a coastal city that underwent significant growth during the 20th century. Annaba has a metropolitan area with a higher population density than the other metropolitan areas of the Algerian coastline, such as Oran and Algiers. Much of eastern and southern Algeria uses the services, equipment and infrastructure of Annaba. Economically, it is the centre for various economic activities, such as industry, transportation, finance, and tourism. Names Present-day Annaba grew up on the site of Aphrodisium, the seaport of the Roman city . (The modern city ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geophilus Electricus
''Geophilus electricus'' is a species of soil centipede in the family Geophilidae found across temperate Europe, especially Britain and Ireland. Originally discovered and named ''Scolopendra electrica'' in 1758, it was later moved to its own genus, Geophilus. As the first species described in this genus, it is considered by some to be the type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen ... (along with '' Geophilus carpophagus''). It is yellowish-orange in color and can grow up to 45 millimeters, with 55 to 75 leg pairs (more than other similar ''Geophilus'' species), a distinct carpophagus fossae on the anterior sternites, and a distinctive arrangement of the coxal pores of the last leg pair. Like many geophilomorphans, ''G. electricus'' has been known to glow in the da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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 ...

Sclerite
A sclerite (Greek , ', meaning "hard") is a hardened body part. In various branches of biology the term is applied to various structures, but not as a rule to vertebrate anatomical features such as bones and teeth. Instead it refers most commonly to the hardened parts of arthropod exoskeletons and the internal spicules of invertebrates such as certain sponges and soft corals. In paleontology, a scleritome is the complete set of sclerites of an organism, often all that is known from fossil invertebrates. Sclerites in combination Sclerites may occur practically isolated in an organism, such as the sting of a cone shell. Also, they can be more or less scattered, such as tufts of defensive sharp, mineralised bristles as in many marine Polychaetes. Or, they can occur as structured, but unconnected or loosely connected arrays, such as the mineral "teeth" in the radula of many Mollusca, the valves of Chitons, the beak of Cephalopod, or the articulated exoskeletons of Arthropoda.

Geophilus
''Geophilus '' is a large, heterogeneous genus of soil centipedes in the family Geophilidae largely considered to be synonymous with '' Brachygeophilus''. It is a mostly holarctic genus characterized by a claw-shaped ultimate pretarsus, anterior porefields, complete or nearly complete coxo-pleural sutures at the prosternum, and incomplete chitin-lines. The generic name first appeared in Brewster's Edinburgh Encyclopaedia in 1814 as ''Geophilus electricus''. Although centipedes in this genus can have as many as 89 pairs of legs, most species have a much smaller number of leg pairs. For example, two species in this genus include centipedes with only 29 pairs of legs, the lowest number found in the family Geophilidae: '' G. persephones'' (29 pairs in the only specimen, a male) and '' G. richardi'' (29 or 31 pairs in males and 33 pairs in females). This genus also includes other species with notably few legs, for example, ''G. hadesi'' (33 pairs in both males and females) and ''G ...
