Yanomamius Neblina
''Yanomamius'' is a genus of South American tarantulas first erected by Rogério Bertani and M. Q. Almeida in 2021 for two newly discovered species and one previously described species from Brazil. In one of Bertani's prior studies, he investigated a tarantula collected by the Yanomami as a source of food. Based on the limited material available for study- two adult females and one immature spider- the species was placed into ''Holothele''. The next year, it was moved to newly erected genus ''Guyruita'' due, in part, to the multi-lobed shape of its spermathecae. When the first male was found and described, the diagnostic characteristics didn't match that of ''Holothele'' or ''Guyruita'', so a new genus was erected for ''Y. waikoshiemi'' and three other closely related species. Species it contains four species: *'' Y. franciscoi'' Bertani & Almeida, 2021 (type) – Brazil *'' Y. neblina'' Bertani & Almeida, 2021 – Brazil *'' Y. raonii'' Bertani & Almeida, 2021 – Brazil *'' Y. ...

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] |
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 ...

Tarantula
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. , 1,040 species have been identified, with 156 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes. Overview Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support.Pomeroy, R. (2014, February 4). Pub.

Yanomami
The Yanomami, also spelled Yąnomamö or Yanomama, are a group of approximately 35,000 indigenous people who live in some 200–250 villages in the Amazon rainforest on the border between Venezuela and Brazil. Etymology The ethnonym ''Yanomami'' was produced by anthropologists on the basis of the word , which, in the expression , signifies "human beings." This expression is opposed to the categories (game animals) and (invisible or nameless beings), but also (enemy, stranger, non-Indian). According to ethnologist : History The first report of the Yanomami to the Northern world is from 1654, when an El Salvadorian expedition under Apolinar Diez de la Fuente visited some Ye'kuana people living on the Padamo River. Diez wrote: From approximately 1630 to 1720, the other river-based indigenous societies who lived in the same region were wiped out or reduced as a result of slave-hunting expeditions by the conquistadors and bandeirantes. How this affected the Yanomami is unk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holothele
''Holothele'' is a genus of tarantulas that was first described by Ferdinand Anton Franz Karsch in 1879. Originally placed with the curtain-web spiders, it was transferred to the tarantulas in 1980. Diagnosis They can be distinguished by the lack of urticating hairs, tarsus 4 being pseudo segmented. The tarsal claws own a row of teeth, and a labium with around 90 cuspules. Species it contains six species, found in the West Indies and in the north of South America: *'' Holothele culebrae'' ( Petrunkevitch, 1929) – Puerto Rico *'' Holothele denticulata'' (Franganillo, 1930) – Cuba *'' Holothele longipes'' (L.

Spermatheca
The spermatheca (pronounced plural: spermathecae ), also called receptaculum seminis (plural: 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 fertilization 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] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
