Geophilus Pygmaeus
''Geophilus pygmaeus'' is a species of soil centipede in the family Geophilidae found in the Southern Limestone Alps, between the Bergamasque Prealps in the west and the Slovene Prealps in the east, and in the northernmost Dinarides. Past records from other areas are usually false. ''G. pygmaeus'' is less than 20 millimeters long and has 41–47 leg pairs. It differs from other European species of Geophilus by the shape of the forcipular apparatus and arrangement of 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.

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 ...

Southern Limestone Alps
The Southern Limestone Alps ( it, Alpi Sud-orientali, german: Südliche Kalkalpen), also called the Southern Calcareous Alps, are the ranges of the Eastern Alps south of the Central Eastern Alps mainly located in northern Italy and the adjacent lands of Austria and Slovenia. The distinction from the Central Alps, where the higher peaks are located, is based on differences in geological composition. The Southern Limestone Alps extend from the Sobretta- Gavia range in Lombardy in the west to the Pohorje in Slovenia in the east. Alpine Club classification Ranges of the Southern Limestone Alps according to the Alpine Club classification (from east to west): * Pohorje (1) * Kamnik–Savinja Alps (2) * Karawanks (3) * Julian Alps (4) * Gailtal Alps (5) * Carnic Alps (6) * Southern Carnic Alps (7) * Dolomites (8) * Fiemme Mountains (9) * Vicentine Alps (10) * Nonsberg Group (11) * Brenta Group (12) * Garda Mountains (13) * Ortler Alps (14) * Adamello-Presanella Alps (15) * Sobretta ...

Bergamasque Prealps
The Bergamasque Prealps () are a mountain range within the Alps. The range is located in Lombardy, in the north of Italy. Geography Administratively the range belongs to the Italian province of Bergamo and, to a lesser extent, to the provinces of Lecco and Brescia. The western slopes of the mountains are drained by the Adda, the central and eastern part of the range by Oglio and other minor rivers and streams, all of them tributaries of the Po. SOIUSA classification According to SOIUSA (''International Standardized Mountain Subdivision of the Alps'') the mountain range is an Alpine subsection, classified in the following way: * main part = Eastern Alps * major sector = Southern Limestone Alps * section = Bergamasque Alps and Prealps * subsection = Bergamasque Prealps * code = II/C-29.II Borders The Bergamo Prealps stretch between Lake Como (west) and Lake Iseo (east). They are separated from the Bergamo Alps (north) by some secondary valleys of Val Brembana, Val Seriana and Va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slovene Prealps
The Slovene Prealps or the Slovenian Prealps ( sl, Slovenske Predalpe, , ) are a group of mountain ranges in the eastern part of the Alps. They are located in Slovenia and, for a small part of their northernmost area, in Austria. Geography SOIUSA classification According to SOIUSA (''International Standardized Mountain Subdivision of the Alps'') the Slovene Prealps are an Alpine section, classified in the following way: * main part = Eastern Alps * major sector = Southern Limestone Alps * section = Slovene Prealps * code = II/C-36 Subdivision The Slovene Prealps are divided into three non-contiguous subsections: * Western Slovene Prealps ( Sl: ''Zahodne Slovenske Predalpe'') - SOIUSA code:II/C-36.I * Eastern Slovene Prealps ( Sl: ''Vzhodne Slovenske Predalpe'') - SOIUSA code:II/C-36.II * Northeastern Slovene Prealps ( Sl: ''Severovzhodne Slovenske Predalpe'') - SOIUSA code:II/C-36.III Two of these subsections include just one Alpine supergroup, and the third one is furth ...

Dinarides
The Dinaric Alps (), also Dinarides, are a mountain range in Southern and Southcentral Europe, separating the continental Balkan Peninsula from the Adriatic Sea. They stretch from Italy in the northwest through Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, and Kosovo to Albania in the southeast. The Dinaric Alps extend for approximately along the western Balkan peninsula from the Julian Alps of the northeast Italy, downwards to the Šar and Korab massif, where their direction changes. The Accursed Mountains, is the highest section of the entire Dinaric Alps; this section stretches from Albania to Kosovo and eastern Montenegro. Maja Jezercë is the highest peak and is located in Albania, standing at above the Adriatic. The Dinaric Alps are one of the most rugged and extensive mountainous areas of Europe, alongside the Caucasus Mountains, Alps, Pyrenees, Carpathian Mountains and Scandinavian Mountains. They are formed largely of Mesozoic and Cenozoic sediment ... [...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 ...

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] |
