Stenaelurillus Mirabilis
''Stenaelurillus mirabilis'' is a species of jumping spider in the genus ''Stenaelurillus'' that lives in Kenya and Tanzania. It was first described in 2000 by Wanda Wesołowska and Anthony Russell-Smith. The spider is medium-sized, with a dark brown carapace between in length that has two white stripes across its length and a black abdomen between long. The female abdomen has orange sides and a white marking of a single stripe interrupted by other marks. The male abdomen has a white cross shape formed of five spors. It is distinguished from other members of the genus by the male's long, thin palpal bulb and the female's epigyne with its short and slightly bent insemination ducts. Taxonomy ''Stenaelurillus mirabilis'' was first described by Wanda Wesołowska and Anthony Russell-Smith in 2000. It is one of over 500 species identified by the Polish arachnologist Wesołowska. It was placed in the genus ''Stenaelurillus'', first raised by Eugène Simon in 1885. The name relates to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stenaelurillus
''Stenaelurillus'' is a genus of jumping spiders that was first described by Eugène Louis Simon in 1886. Most species live in Africa, with some species found in Asia, including China. All species have two white longitudinal stripes on the carapace, and both sexes show strong bristles around the eyes. The name is a combination of the Greek ''sten-'' "narrow" and the salticid genus '' Aelurillus''. Species it contains forty-six species, found only in Africa and Asia: *''Stenaelurillus abramovi'' Logunov, 2008 – Thailand, Vietnam *'' Stenaelurillus albopunctatus'' Caporiacco, 1949 – Kenya *''Stenaelurillus albus'' Sebastian, Sankaran, Malamel & Joseph, 2015 – India *''Stenaelurillus arambagensis'' (Biswas & Biswas, 1992) – India *''Stenaelurillus bandama'' Logunov & Azarkina, 2018 – Ivory Coast *''Stenaelurillus belihuloya'' Logunov & Azarkina, 2018 – Sri Lanka *''Stenaelurillus brandbergensis'' ( Wesolowska, 2006) – Namibia *''Stenaelurillus darwini'' Wesolowska & R ...

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] |
Tsavo East National Park
Tsavo East National Park is a national park in Kenya with an area of . It was established in April 1948 and covers a semi-arid area previously known as the Taru Desert. Together with the Tsavo West National Park, it forms an area of about 22,000 square kilometers. The Tsavo River flows west to east through the national park, which is located in the Taita-Taveta County of the former Coast Province. Geography Tsavo East National Park is generally flat, with dry plains across which the Galana River flows. Other features include the Yatta Plateau and Lugard Falls. Inside Tsavo East National Park, the Athi and Tsavo rivers converge to form the Athi-Galana-Sabaki River. Most of the park consists of semi-arid grasslands and savanna. The Yatta Plateau, the world's longest lava flow, runs along the western boundary of the park above the Athi-Galana-Sabaki River. Its length was formed by lava from Ol Donyo Sabuk Mountain.

Combretum
''Combretum'', the bushwillows or combretums, make up the type genus of the family Combretaceae. The genus comprises about 272 species of trees and shrubs, most of which are native to Tropics, tropical and southern Africa, about 5 to Madagascar, but there are others that are native to tropical Asia, New Guinea and the Bismarck Archipelago, Australia, and Neotropics, tropical America. Around 17 species in the genus Quisqualis are very similar to Combretum and are now classified as species of the genus. Though somewhat reminiscent of willows (''Salix'') in their Morphology (biology), habitus, they are not particularly close relatives of these. Ecology Bushwillow trees often are important plants in their habitat. Savannahs in Africa, in particular those growing on granite, granitic soils, are often dominated by ''Combretum'' and its close relative ''Terminalia (plant), Terminalia''. For example, ''C. apiculatum'' is a notable tree in the Angolan mopane woodlands ecoregion in the K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acacia Senegal
''Senegalia senegal'' (also known as ''Acacia senegal'') is a small thorny deciduous tree from the genus ''Senegalia'', which is known by several common names, including gum acacia, gum arabic tree, Sudan gum and Sudan gum arabic. In parts of India, it is known as kher, khor, or kumatiya. It is native to semi-desert regions of Sub-Saharan Africa, as well as Oman, Pakistan, and west coastal India. It grows to a height of 5–12 metres (16-40'), with a trunk up to 30 cm (1') in diameter. Sudan is the source of the world's highest quality gum arabic, known locally as hashab gum in contrast to the related, but inferior, gum arabic from Red acacia or talah gum. Uses Gum arabic The tree is of great economic importance for the gum arabic it produces which is used as a food additive, in crafts, and as a cosmetic. The gum is drained from cuts in the bark, and an individual tree will yield 200 to 300 grams (7 to 10 oz). Eighty percent of the world's gum arabic is produced ...

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 ...

Stenaelurillus Ignobilis
''Stenaelurillus ignobilis'' is a species of jumping spider in the genus ''Stenaelurillus'' that lives in Zimbabwe. The female was first described in 2011 by Wanda Wesołowska and Meg Cumming. The male has yet to be described. The spider takes its name from a Latin word that can be translated unsightly. The spider is medium-sized, with a carapace long and abdomen long. The carapace is brown, covered in bristles and has an almost indiscernible stripe, while the abdomen is larger and has a stripe of lighter brown down the middle of its generally darker, nearly black. The long spinnerets are also hairy while the legs have both hairs and spines. It is similar to ''Stenaelurillus mirabilis'' but can be distinguished by the design of the epigyne, and particularly the way that the gonopores are hidden in deep cup-like depressions. Taxonomy ''Stenaelurillus ignobilis'' was first described by Wanda Wesołowska and Meg Cumming in 2011. It is one of over 500 species identified by the Poli ...

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 ...

Spermatheca
The spermatheca (pronounced : spermathecae ), also called ''receptaculum seminis'' (: ''receptacula seminis''), is an organ of the female reproductive tract in insects, e.g. ants, bees, some molluscs, Oligochaeta worms and certain other invertebrates and vertebrates. Its purpose is to receive and store sperm from the male or, in the case of hermaphrodites, the male component of the body. Spermathecae can sometimes be the site of fertilisation when the oocytes are sufficiently developed. Some species of animal have multiple spermathecae. For example, certain species of earthworms have four pairs of spermathecae—one pair each in the 6th, 7th, 8th, and 9th segments. The spermathecae receive and store the spermatozoa of another earthworm during copulation. They are lined with epithelium and are variable in shape: some are thin, heavily coiled tubes, while others are vague outpocketings from the main reproductive tract. It is one of the many variations in sexual reproduct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sclerotization
Sclerotization is a biochemical process that produces the rigid shell of sclerotin that comprises an insect's chitinous exoskeleton. It is prominent in the thicker, armored parts of insects and arachnid Arachnids are arthropods in the Class (biology), class Arachnida () of the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, opiliones, harvestmen, Solifugae, camel spiders, Amblypygi, wh ...s, especially in the biting mouthparts and sclerites of scorpions and beetles. Molecular mechanism Sclerotization entails crosslinking of oxygen-reactive derivatives of dopamine. The reaction of the dopamine derivatives toward oxygen is catalyzed by diverse enzymes such as laccase, which convert the catechol groups to quinones. The resulting quinones are susceptible to nucleophilic attack by amines and thiols, which decorate the side-chains of proteins. These reactions gives rise to color (typically brown), loss of solubili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palpal Bulb
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 and ...
