Asiolasma Schwendingeri
''Asiolasma schwendingeri'' is a species of harvestmen belonging to the family Nemastomatidae. It is found in Vietnam, Ha Noi Province. It was described in the genus ''Asiolasma ''Asiolasma'' is a genus of harvestman, harvestmen in the family Nemastomatidae with six described species (as of 2023). The species are found in Southeast Asia, namely China, Vietnam and Thailand. Some species are treated under other genera in S ...''. Description ''Asiolasma schwendingeri'' is said to be the largest and leggiest of the genus. The original description indicates it can be diagnosed by the rather flat body, anterior part of prosoma including eye mound and hood slightly elevated (in lateral view). This can give the visual impression of a massive body, and short hood plus slender and fanned tubercles of hood. Else the species is said to have conspicuously long and slender pedipalps that are only found in this species. The pedipalpal tibia and tarsus are notably together longer than femur ( ...

Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harvestmen
The Opiliones (formerly Phalangida) are an Order (biology), order of arachnids, Common name, colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs (see below). , over 6,650 species of harvestmen have been discovered worldwide, although the total number of extant taxon, extant species may exceed 10,000. The order Opiliones includes five suborders: Cyphophthalmi, Eupnoi, Dyspnoi, Laniatores, and Tetrophthalmi, which were named in 2014. Representatives of each extant suborder can be found on all continents except Antarctica. Well-preserved fossils have been found in the 400-million-year-old Rhynie cherts of Scotland, and 305-million-year-old rocks in France. These fossils look surprisingly modern, indicating that their basic body shape developed very early on, and, at least in some taxa, has changed little since that time. Their Phylogenetics, phylogenetic position within the Arachnida is disputed; their closest relatives may be camel spiders (Solifugae ...

Nemastomatidae
The Nemastomatidae are a family of harvestmen with about 170 described species in 16 recent genera. Several fossil species and genera are known. Unlike some related currently recognized families, the Nemastomatidae are monophyletic. (2007): Nemastomatidae. Simon, 1872. In: Pinto-da-Rocha et al. 2007: 148ff Description Members of the Nemastomatidae range in body length from about one to almost six millimeters. Their chelicerae are of normal proportions, but the pedipalps are very elongated and thin in some groups. Leg length is likewise variable. Distribution The Nemastomatidae are divided into two subfamilies. The subfamily Ortholasmatinae occur on both sides of the Pacific Ocean: in western North America from Alaska and British Columbia to Mexico and possibly Honduras, but also eastern Asia (China, Japan Thailand and Vietnam). The subfamily Nemastomatinae occur across Europe and near, including Iceland and the Caucasus, plus in the Atlas Mountains of North Africa, from Anatoli ...

Vietnam
Vietnam, officially the Socialist Republic of Vietnam (SRV), is a country at the eastern edge of mainland Southeast Asia, with an area of about and a population of over 100 million, making it the world's List of countries and dependencies by population, fifteenth-most populous country. One of two communist states in Southeast Asia, Vietnam shares land borders with China to the north, and Laos and Cambodia to the west. It shares Maritime boundary, maritime borders with Thailand through the Gulf of Thailand, and the Philippines, Indonesia, and Malaysia through the South China Sea. Its capital is Hanoi and its largest city is Ho Chi Minh City. Vietnam was inhabited by the Paleolithic age, with states established in the first millennium BC on the Red River Delta in modern-day northern Vietnam. Before the Han dynasty's invasion, Vietnam was marked by a vibrant mix of religion, culture, and social norms. The Han dynasty annexed Northern and Central Vietnam, which were subs ...

Asiolasma
''Asiolasma'' is a genus of harvestman, harvestmen in the family Nemastomatidae with six described species (as of 2023). The species are found in Southeast Asia, namely China, Vietnam and Thailand. Some species are treated under other genera in Schönhofer (2013). Description The genus ''Asiolasma'' was described by Jochen Martens, with the nominated type species ''Dendrolasma angka'' Schwendinger & Gruber (1992). In the past, this species was alternatively placed in ''Cladolasma'', Another species was later described as ''Cladolasma damingshan'' Zhang & Zhang (2013), but both have since been transferred. Species These six species belong to the genus ''Asiolasma'': * ''Asiolasma ailaoshan'' (Zhang, Zhao & Zhang, 2018)China * ''Asiolasma angka'' (Schwendinger & Gruber, 1992)Thailand * ''Asiolasma billsheari'' Martens, 2019China * ''Asiolasma damingshan'' (Zhang & Zhang, 2013)China * ''Asiolasma juergengruberi'' Martens, 2019China * ''Asiolasma schwendingeri'' Martens, 2019Vietnam ...

Arachnids Of Vietnam
Arachnids are arthropods in the class Arachnida () of the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, harvestmen, camel spiders, whip spiders and vinegaroons. Adult arachnids have eight legs attached to the cephalothorax. In some species the frontmost pair of legs has converted to a sensory function, while in others, different appendages can grow large enough to take on the appearance of extra pairs of legs. Almost all extant arachnids are terrestrial, living mainly on land. However, some inhabit freshwater environments and, with the exception of the pelagic zone, marine environments as well. They comprise over 110,000 named species, of which 51,000 are species of spiders. The term is derived from the Greek word (''aráchnē'', 'spider'), from the myth of the hubristic human weaver Arachne, who was turned into a spider. Morphology Almost all adult arachnids have eight legs, unlike adult insects which all ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
