Geophilus Mordax
''Geophilus mordax'', also called the pitted soil centipede, is a species of soil centipede in the family Geophilidae found in North America, especially Indiana, Arkansas, Louisiana, North and South Carolina, and Florida. It grows up to 50 millimeters in length, though it averages 25–40, has 49–53 leg pairs in males and 49–57 in females, and is bright red in color. ''G. mordax'' also bears 3–5 labral teeth, a short and robust apical claw of the second maxillae, an exposed prebasal plate, and a large, consolidated sacculi. Taxonomy ''G. mordax'' is often confused with '' G. ampyx'', though it can be differentiated by the presence of a sacculus or pit on each sternite. It is polymorphic and may comprise two separate subspecies, one with lateral coxo-pleural The pleural cavity, pleural space, or interpleural space is the potential space between the pleurae of the pleural sac that surrounds each lung. A small amount of serous pleural fluid is maintained in the pleural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Taxa Named By Frederik Vilhelm August Meinert
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Pleuron (insect Anatomy)
The pleuron (pl. pleura, from Greek side, rib) is a lateral sclerite of thoracic segment of an insect between the tergum and the sternum. The terms pro-, meso- and metapleuron The metathorax is the posterior of the three segments in the thorax of an insect, and bears the third pair of legs. Its principal sclerites ( exoskeletal plates) are the metanotum (dorsal), the metasternum (ventral), and the metapleuron (lateral) ... are used respectively for the pleura of the first, second and third thoracic segments.

Arthropod Leg
The arthropod leg is a form of jointed appendage of arthropods, usually used for walking. Many of the terms used for arthropod leg segments (called podomeres) are of Latin origin, and may be confused with terms for bones: ''coxa'' (meaning hip, plural ''coxae''), ''trochanter'', ''femur'' (plural ''femora''), ''tibia'' (plural ''tibiae''), ''tarsus'' (plural ''tarsi''), ''ischium'' (plural ''ischia''), ''metatarsus'', ''carpus'', ''dactylus'' (meaning finger), ''patella'' (plural ''patellae''). Homologies of leg segments between groups are difficult to prove and are the source of much argument. Some authors posit up to eleven segments per leg for the most recent common ancestor of extant arthropods but modern arthropods have eight or fewer. It has been argued that the ancestral leg need not have been so complex, and that other events, such as successive loss of function of a ''Hox''-gene, could result in parallel gains of leg segments. In arthropods, each of the leg segments ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geophilus Ampyx
''Geophilus ampyx'' is a species of soil centipede in the family Geophilidae found in North America, especially South Carolina. It grows up to 52 millimeters in length, though it averages 30–40, has 49–53 leg pairs in males and 51–55 in females, and is bright red in color. ''G. ampyx'' also bears five sclerotized and deeply pigmented labral teeth and a nearly entirely exposed prebasal plate. It's often confused with '' G. mordax'', though it can be differentiated by the absence of sacculi.

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Brolemann
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] |
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 ...

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 ...
