Langona Sabulosa
''Langona sabulosa'' is a species of jumping spider in the genus ''Langona'' that lives in Namibia. It was first described in 2011 by Wanda Wesołowska. The spider is large with a cephalothorax between long and a abdomen between . The female is noticeably larger than the male and has a very different shape to its much larger abdomen, being more heart-shaped than oval. It has the toothless chelicerae typical of the genus. The abdomen has a large leaf-like pattern, which differentiates it from other species in the genus, as can the yellowish-orange colour of the pedipalps on the male. The female has a unique epigyne that led Wesołowska to question where it should be allocated in the subtribe Aelurillina. Taxonomy ''Langona sabulosa'' ia a jumping spider that was first described by the Polish arachnologist Wanda Wesołowska in 2011. It was one of over 500 species that she has identified. She placed it in the genus ''Langona'', first described by Eugène Simon in 1901, on the bas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Carapace
A carapace is a dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. In botany, a carapace refers to the hard outer cover of a seed which protects the inner embryo. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum. The carapace is calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keetmanshoop
Keetmanshoop is a town in the ǁKaras Region of southern Namibia. It is named after , a German Empire, German industrialist and benefactor of the city. Keetmanshoop had a population of 27,862 people in 2023. History Before the colonial era, the settlement was known as ''ǂNuǂgoaes'' or ''Swartmodder'', both meaning "Black Marsh" and indicating the presence of a spring in the area. The first white settler, Guilliam Visagie, arrived here in 1785. When in February 1850 the Kharoǃoan clan (Keetmanshoop Nama) split from the Red Nation (Namibia), Red Nation, the main subtribe of the Nama people, they settled permanently in the area. In 1860 the Rhenish Missionary Society founded a mission there to christianise the local Nama people. The first missionary, Johann Georg Schröder, arrived in Keetmanshoop on April 14, 1866, which is now marked as the founding date of Keetmanshoop. The mission station was named after the German trader and director of the Rhenish Missionary Society, , w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes, with little or no vegetation, are called ''Erg (landform), ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the wiktionary:stoss, stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of Outwash plain, glacial outwash ...

Karasburg
Karasburg (, old name , literally "carst spring") is a town in the ǁKaras Region of southern Namibia and the district capital of the Karasburg electoral constituency. It lies at the heart of the southern Namibian sheep farming industry. Karasburg had a population of 6,621 people in 2023. Geography There are three main routes that lead into Karasburg. From Grünau in the west, Onseepkans in the south and the B3 national road that leads to the South African border in the east. The town lies south of Windhoek, north of Cape Town and west of the Ariamsvlei border post. Karasburg is the only town south of Keetmanshoop in Namibia. Climate Karasburg has an extreme climate most of the year with temperatures rising well over 40 degrees Celsius in summer and dropping to sub-zero in winter. Low rainfall is experienced in this region (annual average rainfall: at the Karasburg weather station), the rainy season usually arriving in early January and leaving as late as early A ...

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Langona Hirsuta
''Langona hirsuta'' is a species of jumping spider in the genus ''Langona'' that lives in South Africa. It was first described in 2011 by Charles Haddad and Wanda Wesołowska. The spider is large with a carapace between long and a abdomen between long. The female is significantly larger than the male, particularly in the abdomen, which is also wider and a lighter brown. The male has very hairy pedipalps, after which it is named. It has the toothless chelicerae typical of the genus, and a single appendage, or apophysis, on the palpal tibia. The length of the apophysis helps to distinguish it from other spiders in the genus. It lives in semi-arid climates. Taxonomy ''Langona hirsuta'' is a jumping spider that was first described by Wanda Wesołowska and Charles Haddad in 2011. It isone of over 500 species identified by the Polish arachnologist Wesołowska during her career. The species was placed in the genus ''Langona'', first described by Eugène Simon in 1901.

Gonopore
A gonopore, sometimes called a gonadopore, is a genital pore in many invertebrates. Hexapods, including insects, have a single common gonopore, except mayflies, which have a pair of gonopores. More specifically, in the unmodified female, it is the opening of the common oviduct, and in the male, it is the opening of the ejaculatory duct. The position of the gonopore varies considerably between groups, but is generally constant within groups, allowing its position to be used as a "segmental marker". In Malacostraca, it is on the sixth thoracic segment; in Symphyla, it is on the fourth trunk segment; in arachnids, it is on the second segment of the opisthosoma. In insects and centipedes, the gonopores are close to the animal's tail, while in millipede Millipedes (originating from the Latin , "thousand", and , "foot") are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Dipl ...

Embolus (spider Anatomy)
The two palpal bulbs – also known as palpal organs and genital bulbs – are the copulatory organs of a male spider. They are borne on the last segment of the pedipalps (the front "limbs" of a spider), giving the spider an appearance often described as like wearing boxing gloves. The palpal bulb does not actually produce sperm, being used only to transfer it to the female. Palpal bulbs are only fully developed in adult male spiders and are not completely visible until after the final moult. In the majority of species of spider, the bulbs have complex shapes and are important in identification. Structure The palpal bulb of a mature male spider is borne on the last segment of the pedipalp. This segment usually has touch-sensitive hairs (setae) with nerves leading to them. The bulb itself is entirely without nerves, and hence without sensory organs and muscles, since these depend on nerves for their functioning, although some spiders have one or two muscles external to the bulb an ...
