Lipseuma Josianae
''Lipseuma'' is a genus of Millipede, millipedes in the Family (biology), family Kashmireumatidae. This genus contains only two species, the type species ''Lipseuma josianae, L. josianae'' and its close relative ''Lipseuma bernardi, L. bernardi''. Both species are List of troglobites, troglobites found in caves in China. The species in this genus are notable for featuring Gonopod, gonopods that are among the simplest in the order Chordeumatida. Discovery and distribution This genus and its two species were first described in 2006 by the Myriapodology, myriapodologist species:Sergei_Ilyich_Golovatch, Sergei Golovatch of the Russian Academy of Sciences and two myriapodologists at the National Museum of Natural History, France, Muséum National d’Histoire Naturelle in France, species:Jean-Jacques_Geoffroy, Jean-Jacques Geoffroy and species:Jean-Paul_Mauriès, Jean-Paul Mauriès. The original descriptions are based on specimens collected in 1999 by the Biospeleology, biospeleologis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Telson
The telson () is the hindmost division of the body of an arthropod. Depending on the definition, the telson is either considered to be the final segment (biology), segment of the arthropod body, or an additional division that is not a true segment on account of not arising in the embryo from teloblast areas as other segments. It never carries any appendages, but a forked "tail" called the caudal furca may be present. The shape and composition of the telson differs between arthropod groups. Crustaceans In lobsters, Caridea, shrimp and other Decapoda, decapods, the telson, along with the uropods, forms the tail fan. This is used as a paddle in the caridoid escape reaction ("lobstering"), whereby an alarmed animal rapidly flexes its tail, causing it to dart backwards. Krill can reach speeds of over 60 cm per second by this means. The Induction period, trigger time to optical stimulus (physiology), stimulus is, in spite of the low temperatures, only 55 milliseconds. In th ...

Troglomorphism
Troglomorphism is the morphological adaptation of an animal to living in the constant darkness of caves, characterised by features such as loss of pigment, reduced eyesight or blindness, and frequently with attenuated bodies or appendages. The terms troglobitic, stygobitic, stygofauna, troglofauna, and hypogean or hypogeic, are often used for cave-dwelling organisms. Troglomorphism occurs in molluscs, velvet worms, arthropods, fish, amphibians (notably cave salamanders) and reptiles. To date no mammals or birds have been found to live exclusively in caves. Pickerel frogs are classed as either trogloxenes, or possibly troglophiles. The first Troglobiont to be described was ''Leptodirus hochenwartii.'' Morphology of Troglomorphism Troglomorphic species must adapt to unique elements of subterranean life, like continual darkness, reduced season queues, and limited food availability. The reduction of characters like eyes and pigmentation is generally considered to be an evolutionary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paris
Paris () is the Capital city, capital and List of communes in France with over 20,000 inhabitants, largest city of France. With an estimated population of 2,048,472 residents in January 2025 in an area of more than , Paris is the List of cities in the European Union by population within city limits, fourth-most populous city in the European Union and the List of cities proper by population density, 30th most densely populated city in the world in 2022. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, culture, Fashion capital, fashion, and gastronomy. Because of its leading role in the French art, arts and Science and technology in France, sciences and its early adoption of extensive street lighting, Paris became known as the City of Light in the 19th century. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an official estimated population of 12,271,794 inhabitants in January 2023, or ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the scientific name of every taxon is ...

Sichuan
Sichuan is a province in Southwestern China, occupying the Sichuan Basin and Tibetan Plateau—between the Jinsha River to the west, the Daba Mountains to the north, and the Yunnan–Guizhou Plateau to the south. Its capital city is Chengdu, and its population stands at 83 million. Sichuan neighbors Qinghai and Gansu to the north, Shaanxi and Chongqing to the east, Guizhou and Yunnan to the south, and Tibet to the west. During antiquity, Sichuan was home to the kingdoms of Ba and Shu until their incorporation by the Qin. During the Three Kingdoms era (220–280), Liu Bei's state of Shu was based in Sichuan. The area was devastated in the 17th century by Zhang Xianzhong's rebellion and the area's subsequent Manchu conquest, but recovered to become one of China's most productive areas by the 19th century. During World War II, Chongqing served as the temporary capital of the Republic of China, and was heavily bombed. It was one of the last mainland areas captured ...

Hubei
Hubei is a province of China, province in Central China. It has the List of Chinese provincial-level divisions by GDP, seventh-largest economy among Chinese provinces, the second-largest within Central China, and the third-largest among inland provinces. Its provincial capital at Wuhan serves as a major political, cultural, and economic hub for the region. Hubei is associated with the historical state of E that existed during the Western Zhou dynasty (771 BCE). Its name means 'north of the lake', referring to Dongting Lake. It borders Henan to the north, Anhui and Jiangxi to the east, Hunan to the south, and Chongqing and Shaanxi to the west. The high-profile Three Gorges Dam is located at Yichang in the west of the province. History The Hubei region was home to sophisticated Neolithic cultures. By the Spring and Autumn period (770–476 BC), the territory of today's Hubei formed part of the powerful Chu (state), State of Chu. Chu, nominally a tributary state of the Zh ...

Paratype
In zoology and botany, a paratype is a specimen of an organism that helps define what the scientific name of a species and other taxon actually represents, but it is not the holotype (and in botany is also neither an isotype (biology), isotype nor a syntype). Often there is more than one paratype. Paratypes are usually held in museum research collections. The exact meaning of the term ''paratype'' when it is used in zoology is not the same as the meaning when it is used in botany. In both cases however, this term is used in conjunction with ''holotype''. Zoology In zoological nomenclature, a paratype is officially defined as "Each specimen of a type series other than the holotype.", ''International Code of Zoological Nomenclature'' In turn, this definition relies on the definition of a "type series". A type series is the material (specimens of organisms) that was cited in the original publication of the new species or subspecies, and was not excluded from being type material ...
