Geophilus Gracilis
''Geophilus gracilis'' 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 most commonly in Britain and Ireland, though specimens have also been recorded in Chile, France, Greece, and Algeria. It lives under mud and stones along the coast near or below the high tide mark, grows up to 30 millimeters in length, and is bright yellow in color with a darker reddish head. Males of this species have 51 to 57 pairs of legs; females have 51 to 61 leg pairs. This species is often confused with '' G. flavus'' and, in coastal locations, '' G. osquidatum''.

Brölemann
Henry Wilfred Brolemann (10 July 1860 – 31 July 1933) was a French myriapodologist and former president of the Société entomologique de France known for major works on centipede Centipedes (from New Latin , "hundred", and Latin , " foot") are predatory arthropods belonging to the class Chilopoda (Ancient Greek , ''kheilos'', lip, and New Latin suffix , "foot", describing the forcipules) of the subphylum Myriapoda, an ...s and millipedes, of which he named some 500 species. Brolemann was born on 10 July 1860 in Paris, to a wealthy family of Israelite industrialists and bankers that had long since converted to Protestantism. He graduated from the University of Paris and was in the banking business early in life, then left for studies in the United States, including at Indiana University, and then studied in Italy before returning to France and becoming one of the world's experts in myriapods. Brolemann was fluent in English, German and Italian, and wrote in Spani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Geophilus Flavus
''Geophilus flavus'' is a terrestrial, soil-dwelling, species of centipede in the Geophilidae family. ''G. flavus'' occurs in a range of habitats across central Europe, North America, Australia and other tropical regions. Geophilomorph centipedes, like centipedes generally, are primary predators, hunting predominantly in underground soil burrows or above ground leaf litter. Their consumption behaviours are influenced by environment and seasonal factors. Given their lack of economic value and marginal medical significance, ''G.flavus'' remains largely understudied in mainstream research. Some recent studies have detailed the evolutionary development of ''G.flavus'' and Geophilidae generally, illustrating developed predatory features like forcipule venom glands. Description These centipedes are yellow and may grow up to in length. They are sightless, and rely on specialised sensory organs to sense movement, humidity and light. Like other myriapods, they have an exoskeleton an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geophilus Osquidatum
''Geophilus osquidatum'' 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 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. Ref ...

Geophilus Fucorum
''Geophilus fucorum'' is a halophilic 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 in the French Mediterranean, Corsica, Italy, and Greece. Males of this species have 49 to 53 pairs of legs; females have 51 to 55. Taxonomy ''G. fucorum'' shares several characteristics with both '' G. algarum'' and '' G. gracilis'', which was previously classified as a subspecies of ''G. fucorum'', leading some to believe that the three are a single species consisting of highly individual subspecies. It's differentiated from the two by having 5-7 labral teeth, absence of a clear clypeal area, 12-14 prehensorial teeth, two clustered and one isolated ventral (posterior) pore, and a rudimentary claw of the anal leg.

Geophilus Algarum
''Geophilus algarum'' is a species of centipede in the family Geophilidae found in the littoral zone on the French Atlantic and Channel Coasts. It has one subspecies, ''G. algarum var. decipiens'', which can be identified by lack of a dorsal coxal In vertebrate anatomy, hip (or "coxa"Latin ''coxa'' was used by Celsus in the sense "hip", but by Pliny the Elder in the sense "hip bone" (Diab, p 77) in medical terminology) refers to either an anatomical region or a joint.

Taxonomy ''G. algarum'' shares several characteristics with both '' G. fucorum'' and '' G. gracilis'', leading some to believe that the three are a single polytypic species consisting of highly individual subspecies. ''G. algarum'' is differentiated from the other two centipedes by having two labral teeth, a clear clypeal area, 8–12 prehensorial teeth, three ventral (po ...

Labrum (arthropod Mouthpart)
The labrum is a flap-like structure that lies immediately in front of the mouth in almost all extant Euarthropoda. The most conspicuous exceptions are the Pycnogonida, which probably are chelicerate-relatives. In entomology, the labrum amounts to the "upper lip" of an insect mouth, the corresponding "lower lip" being the labium. The evolutionary origin, embryogenesis and morphological development of the labrum have proved to be by far the most controversial and challenging topic in the study of arthropod head structures. Embryonic nature and origin of the labrum The labrum is innervated in crustaceans and insects from the tritocerebrum (the back of the brain). However, in development, its embryonic primordium often appears at the anterior of the head and migrates backwards towards its adult position. Furthermore, it often appears as a bilobed structure, with a set of muscles, nerves and gene expression in many ways similar to that of an appendage. This evidence has been use ...

Clypeus (arthropod Anatomy)
The clypeus is one of the sclerites that make up the face of an arthropod. In insects, the clypeus delimits the lower margin of the face, with the labrum articulated along the ventral margin of the clypeus. The mandibles bracket the labrum, but do not touch the clypeus. The dorsal margin of the clypeus is below the antennal sockets. The clypeus is often well-defined by sulci ("grooves") along its lateral and dorsal margins, and is most commonly rectangular or trapezoidal in overall shape. The post-clypeus is a large nose-like structure that lies between the eyes and makes up much of the front of the head in cicadas. In spiders, the clypeus is generally the area between the anterior edge of the carapace A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises.
