Rhene Formosa
''Rhene formosa'' is a species of jumping spider in the genus ''Rhene'' that lives in the mountains of Guinea. The female was first identified in 2002 while the male remains unknown. The spider is small, with a line of white hairs on a darker brown carapace and a lighter beige and longer elongated abdomen. Taxonomy ''Rhene formosa'' was first identified by Charles Haddad and Wanda Wesołowska in 2011. It was allocated to the genus ''Rhene'', which is named after the Greek female name, shared by mythological figures, in the family Salticidae. The species name is the Latin for shapely, and recalls the body shape of the spider. Description Only the female has been described. It has a flat, wide, dark brown carapace that is in length. The carapace is hairy, mostly covered with brown and grey hairs, but with a line of white hairs behind the first row of eyes. The abdomen is elongated and light beige, measuring in length. The species is similar to the related '' Rhene pinguis'', b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wanda Wesołowska
Wanda Wesołowska (born 11 August 1950) is a Polish zoologist known for her work with jumping spiders. She has described more species of jumping spider than any contemporary writer, and is second only to Eugène Simon in the history of arachnology. Originally a student of ornithology, she developed an interest in jumping spiders while still a student at the Siedlce University of Natural Sciences and Humanities in the 1970s. She subsequently undertook study into the genus ''Heliophanus'' at the University of Wroclaw. Her subsequent doctoral thesis described 44 new species, and joined the staff at the university. She stayed until retiring in 2020. Her research included the taxonomy and zoogeography of jumping spiders, and has included extensive work on African genera like ''Menemerus'' and ''Pachyballus''. She has identified over 500 species, including half of all those from South Africa, as well as having more than 20 named after her. Early life Wanda Wesołowska (née Nowysz) was ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jumping Spider
Jumping spiders are a group of spiders that constitute the family (biology), family Salticidae. As of 2019, this family contained over 600 described genera and over 6,000 described species, making it the largest family of spiders at 13% of all species. Jumping spiders have some of the best vision among arthropods and use it in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps. Both their book lungs and Invertebrate trachea, tracheal system are well-developed, and they use both systems (bimodal breathing). Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes, with the Anatomical terms of location, anterior median pair being particularly large. Distinguishing characteristics Jumping spiders are among the easiest to distinguish from similar spider f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. 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 ...

Rhene
''Rhene'' is a spider genus of the family Salticidae (jumping spiders). Taxonomy The genus was originally named ''Rhanis'' by C. L. Koch in 1846. However, this name had already been used for a beetle genus in 1834. Accordingly, Tamerlan Thorell provided the replacement name ''Rhene'' in 1869. The name ''Rhene'' is derived from the Greek woman's name '' Rhene'' (). Species , the World Spider Catalog accepted the following extant species: * '' Rhene albigera'' (C. L. Koch, 1846) – India to Korea, Sumatra * '' Rhene amanzi'' Wesołowska & Haddad, 2013 – South Africa * '' Rhene atellana'' (Thorell, 1895) – Myanmar * '' Rhene atrata'' ( Karsch, 1881) – Russia, China, Korea, Taiwan, Japan * '' Rhene banksi'' Peckham & Peckham, 1902 – South Africa * '' Rhene biguttata'' Peckham & Peckham, 1903 – South Africa * '' Rhene brevipes'' (Thorell, 1891) – Sumatra * '' Rhene bufo'' (Doleschall, 1859) – Myanmar to Sumatra * '' Rhene callida'' Peckham & Peckham, 1895 – I ...

Carapace
A carapace is a Dorsum (biology), 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. 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 (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, 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 Plate (animal anatomy), plate which carries the e ...

Abdomen
The abdomen (colloquially called the belly, tummy, midriff, tucky or stomach) is the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. The abdomen is the front part of the abdominal segment of the torso. The area occupied by the abdomen is called the abdominal cavity. In arthropods it is the posterior (anatomy), posterior tagma (biology), tagma of the body; it follows the thorax or cephalothorax. In humans, the abdomen stretches from the thorax at the thoracic diaphragm to the pelvis at the pelvic brim. The pelvic brim stretches from the lumbosacral joint (the intervertebral disc between Lumbar vertebrae, L5 and Vertebra#Sacrum, S1) to the pubic symphysis and is the edge of the pelvic inlet. The space above this inlet and under the thoracic diaphragm is termed the abdominal cavity. The boundary of the abdominal cavity is the abdominal wall in the front and the peritoneal surface at the rear. In vertebrates, the abdomen is a large body c ...

Rhene (mythology)
In Greek mythology, Rhene (Ancient Greek: Ῥήνη) may refer to the following personages: * Rhene, a nymph of Mount Cyllene.Dionysius of Halicarnassus1.61.3/ref> She was the lover of Hermes and mother by him of Saon (or Samon) of Samothrace. * Rhene, also a nymph who was a paramour of Oileus and mother of his son Medon, although some suggest that Oileus fathered Medon with Alcimache. In one source, Rhene is given as the mother of Oileus' another son, Ajax the Lesser, as well, though the latter is more commonly said to be the son of Oileus' legitimate wife Eriopis.Homer, ''Iliad'', 13. 697 with scholia Notes References * Diodorus Siculus, '' The Library of History'' translated by Charles Henry Oldfather.

Rhene Pinguis
''Rhene pinguis'' is a species of jumping spider in the genus ''Rhene'' that was identified in South Africa. The male was first described in 2009 and the female in 2018. The spider is flat and hairy, its swollen look giving rise to its species name. The female is slightly larger than the male, but neither have been seen with a cephalothorax longer than and abdomen more than in length. Taxonomy ''Rhene pinguis'' is a member of the genus ''Rhene'', which is named after the Greek female name, shared by mythological figures. The species name, pinguis, means fat or thick, and relates to the swollen look of the spider. Description The spider was first identified in 2009, with initially only the male described. The female was first described in 2018. The spider is flat, hairy and brown in colour. The male is distinguished by its the wide vane at the tip of the embolus. The female is similar to the related ''Rhene formosa'', but differs in the design of its copulatory opening. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epigyne
The epigyne or epigynum is the external genital structure of female spiders. As the epigyne varies greatly in form in different species, even in closely related ones, it often provides the most distinctive characteristic for recognizing species. It consists of a small, hardened portion of the exoskeleton located on the underside of the abdomen, in front of the epigastric furrow and between the epigastric plates. Functions The primary function of the epigyne is to receive and direct the palpal organ of the male during copulation. The various specific forms of epigynes are correlated, in each case, with corresponding specific differences in the palpus of the male. This specialization prevents individuals of different species from mating. The epigyne covers or accompanies the openings of the spermathecae, which are pouches for receiving and retaining sperm. Frequently, the openings of the spermathecae are on the outer face of the epigyne and can be easily seen. A secondary functi ...

Guinea Highlands
The Guinea Highlands is a densely forested mountainous plateau extending from central Guinea through northern Sierra Leone and Liberia to western Ivory Coast. The highlands include a number of mountains, ranges and plateaus, including the Fouta Djallon highlands in central Guinea, the Loma Mountains in Sierra Leone, the Simandou and Kourandou massifs in southeastern Guinea, the Nimba Range at the border of Guinea, Liberia, and Ivory Coast, and the Monts du Toura in western Ivory Coast. Geography In Guinea they are known as ''Dorsale Guinéenne''. The highest peak in the region is Mount Bintumani in Sierra Leone, at 1,945 metres (6,381 ft). Other peaks include Sankan Biriwa () in Sierra Leone and Mount Richard-Molard (Mount Nimba) () on the border of Guinea and Ivory Coast. The highlands mostly lie between above sea level. The Guinea Highlands are the source of many of West Africa's rivers, including the Niger River, West Africa's longest river, the Senegal and Gamb ...

Fauna Of Guinea
The wildlife of Guinea is very diverse due to the wide variety of different habitats. The southern part of the country lies within Guinean Forests of West Africa Biodiversity Hotspot, while the north-east is characterized by dry savanna woodlands. Ecoregions of Guinea are Western Guinean lowland forest, Guinean montane forest, Guinean forest-savanna mosaic, West Sudanian Savanna, and Guinean mangroves. Declining populations of large mammals are restricted to uninhabited distant parts of parks and reserves, because of the inappropriate nature conservation. A noteworthy NGO specialized to nature conservation is the Guinean Parks. Famous strongholds of Guinean wildlife are Pinselly Classified Forest, National Park of Upper Niger, Badiar National Park, Mount Nimba Strict Nature Reserve, Ziama Massif, Bossou Hills Reserve, and Diécké Classified Forest.
