Stenaelurillus Iubatus
''Stenaelurillus iubatus'' is a species of jumping spider in the genus ''Stenaelurillus'' that in endemic to Nigeria. It was first described in 2011 by Wanda Wesołowska and Anthony Russell-Smith. The spider is medium-sized, with a brown carapace between in length and abdomen between in length. The male has two stripes of white scales on the carapace and the female has a heart-shaped white spot on the abdomen. The spider has a distinctive mane-like long hairs on its black eye field, which is recalled in the species name that is derived from the Latin for mane. It can be distinguished from other species in the genus by the ribbon-shaped embolus on the male and highly sclerotized epigyne with its narrow pocket and widely separated copulatory openings on the female. Taxonomy ''Stenaelurillus iubatus'' was first described by Wanda Wesołowska and Anthony Russell-Smith in 2011. It is one of over 500 species identified by the Polish arachnologist Wesołowska.

Stenaelurillus Albus
''Stenaelurillus albus'' is a species of jumping spider in the genus '' Stenaelurillus'' that lives in India. It was first described in 2015 by Pothalil A. Sebastian, Pradeep M. Sankaran, Jobi J. Malamel and Mathew M. Joseph. The spider was first found in Kerala but has also been observed in Karnataka, including the Mookambika Wildlife Sanctuary and Parambikulam Tiger Reserve. It prefers to live in the leaf litter found in deciduous forests. It is medium-sized, with a body length that ranges from . The female is larger than the male. The female has a black oval cephalothorax which has a pattern of yellow bands and an oval abdomen that has yellow patches, the most pronounced three of which make a triangle shape, on a black background. The male differs in having a shiny black abdomen which has no patterns and a cephalothorax that is black with thick white stripes that mark the spider from front to back. This pattern distinguishes the species from others in the genus, including ''Ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxa ranked above species are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Nigeria
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 becomin ...

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 ...

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 ...

Stenaelurillus Pilosus
''Stenaelurillus pilosus'' is a species of jumping spider in the genus ''Stenaelurillus'' that is endemic to Nigeria. It was first described in 2011 by Wanda Wesołowska and Anthony Russell-Smith. The spider is medium-sized, with a brown carapace between in length and an abdomen between in length. It can be distinguished from other species in the genus by the dark brown band on its clypeus, the distinctive long orangish-brown hairs on its black eye field, the male's straight embolus and the presence of two fissure-like openings in the epigyne on the female. Taxonomy ''Stenaelurillus pilosus'' was first described by Wanda Wesołowska and Anthony Russell-Smith in 2011. It is one of over 500 species identified by the Polish arachnologist Wesołowska. The genus ''Stenaelurillus'' was first raised by Eugène Simon in 1886. The name relates to the genus name '' Aelurillus'', which itself derives from the Greek word for cat, with the addition of a Greek stem meaning narrow.It has be ...

Pedipalp
Pedipalps (commonly shortened to palps or palpi) are the secondary pair of forward appendages among Chelicerata, chelicerates – a group of arthropods including spiders, scorpions, horseshoe crabs, and sea spiders. The pedipalps are lateral to the chelicerae ("jaws") and anterior to the first pair of walking legs. Overview Pedipalps are composed of six segments or articles. From the proximal end (where they are attached to the body) to the distal, they are: the coxa, the Arthropod leg#Trochanter, trochanter, the Arthropod leg#Femur, femur, the short Glossary_of_spider_terms#patella, patella, the Glossary_of_spider_terms#tibia, tibia, and the Arthropod_leg#Tarsus, tarsus. In spiders, the coxae frequently have extensions called Glossary_of_spider_terms#maxilla , maxillae or gnathobases, which function as mouth parts with or without some contribution from the coxae of the anterior arthropod leg, legs. The limbs themselves may be simple tactile organs outwardly resembling the legs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spinnerets
A spinneret is a silk-spinning organ of a spider or the larva of an insect. Some adult insects also have spinnerets, such as those borne on the forelegs of Embioptera. Spinnerets are usually on the underside of a spider's opisthosoma, and are typically segmented. While most spiders have six spinnerets, some have two, four, or eight. They can move both independently and in concert. Most spinnerets are not simple structures with a single orifice producing a single thread, but complex structures of many microscopic spigots, each producing one filament. This produces the necessary orientation of the protein molecules, without which the silk would be weak and useless. Spigots can be singular or found in groups, which also permits spiders to combine multiple filaments in different ways to produce many kinds of silk for various purposes. Spinneret morphology can help arachnologists identify the taxon of a specimen and the specific morphology of a spigot can determine its use as wel ...

Clypeus (arthropod Anatomy)
The clypeus is one of the sclerites that make up the face of an arthropod. In insects, the clypeus delimits the lower margin of the face, with the labrum articulated along the ventral margin of the clypeus. The mandibles bracket the labrum, but do not touch the clypeus. The dorsal margin of the clypeus is below the antennal sockets. The clypeus is often well-defined by sulci ("grooves") along its lateral and dorsal margins, and is most commonly rectangular or trapezoidal in overall shape. The post-clypeus is a large nose-like structure that lies between the eyes and makes up much of the front of the head in cicadas. In spider Spiders (order (biology), order Araneae) are air-breathing arthropods that have eight limbs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude spider silk, silk. They are the largest order of arachnids and ran ...s, the clypeus is generally the area between the anterior edge of the carapace and the anterior eyes ...

Thorax
The thorax (: thoraces or thoraxes) or chest is a part of the anatomy of mammals and other tetrapod animals located between the neck and the abdomen. In insects, crustaceans, and the extinct trilobites, the thorax is one of the three main divisions of the body, each in turn composed of multiple segments. The human thorax includes the thoracic cavity and the thoracic wall. It contains organs including the heart, lungs, and thymus gland, as well as muscles and various other internal structures. The chest may be affected by many diseases, of which the most common symptom is chest pain. Etymology The word thorax comes from the Greek θώραξ ''thṓrax'' " breastplate, cuirass, corslet" via . Humans Structure In humans and other hominids, the thorax is the chest region of the body between the neck and the abdomen, along with its internal organs and other contents. It is mostly protected and supported by the rib cage, spine, and shoulder girdle. Contents The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
