Daesiidae
Daesiidae is a family of solifugids, which are widespread in Africa and the Middle East. Members of the family are also present in India, Italy, South America, the Balkans, and the single species '' Gluvia dorsalis'' in the Iberian Peninsula. A single fossil species is known from Eocene Baltic amber. Genera , the World Solifugae Catalog accepts the following twenty-nine genera: *'' Ammotrechelis'' Roewer, 1934 *''Biton'' Karsch, 1880 *'' Bitonota'' Roewer, 1933 *'' Bitonupa'' Roewer, 1933 *'' Blossia'' Simon, 1880 *'' Blossiana'' Roewer, 1933 *'' Ceratobiton'' Delle Cave & Simonetta, 1971 *'' Daesiola'' Roewer, 1933 *'' Eberlanzia'' Roewer, 1941 *'' Gluvia'' C.L.

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of Genus, genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical o ...

Argentina
Argentina, officially the Argentine Republic, is a country in the southern half of South America. It covers an area of , making it the List of South American countries by area, second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the List of countries and dependencies by area, eighth-largest country in the world. Argentina shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a Federation, federal state subdivided into twenty-three Provinces of Argentina, provinces, and one autonomous city, which is the federal capital and List of cities in Argentina by population, largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a Federalism, federal system. Argentina claims sovereignty ov ...

Solifugae Genera
Solifugae is an order of arachnids known variously as solifuges, sun spiders, camel spiders, and wind scorpions. The order includes more than 1,000 described species in about 147 genera. Despite the common names, they are neither true spiders (order Araneae), nor true scorpions (order Scorpiones). Most species of solifuges live in dry climates and feed opportunistically on ground-dwelling arthropods and other small animals. The largest species grow to a length of , including legs. A number of urban legends exaggerate the size and speed of solifuges, and their potential danger to humans, which is negligible. Etymology The order's name is derived from the Latin ''sol'' meaning "sun" and ''fugere'' meaning "to flee". Put together, it means "those that flee from the sun". These animals have a number of common names, including sun spiders, wind scorpions, wind spiders, red romans, and camel spiders. In Afrikaans, they are known as ''haarskeerders'' ("hair cutters"), and ''baardskeerder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
