Typhochlaena Seladonia
''Typhochlaena seladonia'' is a species of aviculariine tarantula, and is the type species of the genus ''Typhochlaena''. It is unique as an arboreal spider that constructs trapdoors in the bark of trees. The common name is the Brazilian jewel tarantula. Taxonomy ''T. seladonia'' was originally described by Carl Ludwig Koch, in Brazil in 1841, as ''Mygale seladonia''. In 1850 he changed its name to ''Typhochlaena seladonia''; then Eugène Simon changed it again to ''Avicularia seladonia''. In 1928, Candido Mello-Leitão changed the species name back to ''Typhochlaena seladonia'', but Andrew Smith (in 1993) changed it to ''Iridopelma seladonia'', and then Lina Almeida-Silva changed it to ''Iridopelma seladonium''. Rogèrio Bertani finally changed the name back to ''Typhochlaena seladonia'' in 2012. Characteristics The female ''Typhochlaena seladonia'' has long, thin spermathecae, which are spiralled distally. The male has a very long embolus. Additionally, both genders have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aviculariinae
The Aviculariinae are a subfamily of spiders in the family Theraphosidae (tarantulas). They can be distinguished from other theraphosids by a number of characters. Their legs have no or few spines on the underside (ventral surface) of the tibial and metatarsal joints of the legs. The last two leg joints (the metatarsi and tarsi) have brushes of hairs (scopulae) that extend sideways, particularly on the front legs, giving them a spoon-like (spatulate) appearance. Females have two completely separated spermathecae. Taxonomy The earliest classification of the mygalomorph spiders to include sufficient genera to be reasonably comprehensive was that of Eugène Simon in 1892. He recognized only two mygalomorph families; his Avicularidae taxon includes at least 12 modern families. The earliest equivalent to the modern subfamily Aviculariinae is considered to be Simon's 1889 tribe Aviculariae, which included three genera: ''Avicularia'', '' Tapinauchenius'' and ''Scodra'' (now '' Stromato ...

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.

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.

Typhochlaena
''Typhochlaena'' is a genus of small-bodied tarantulas with an arboreal trapdoor lifestyle. All the species except for ''T. seladonia'' were first described by Rogério Bertani in 2012. Characteristics ''Typhochlaena'' differs from all other aviculariine species by having a domed, short distal segment on the posterior lateral spinneret; the sternum is as long as wide, truncated behind; they are also quite small, with type II urticating hairs.Bertani, R.

Carl Ludwig Koch
Carl Ludwig Koch (21 September 1778 – 23 August 1857) was a German entomologist and arachnologist. He was responsible for classifying a great number of spiders, including the Brazilian whiteknee tarantula and common house spider. He was born in Kusel, Germany, and died in Nuremberg, Germany. Carl Ludwig Koch was an inspector of water and forests. His principal work ''Die Arachniden'' (1831–1848) (16 volumes) was commenced by Carl Wilhelm Hahn (1786–1836). Koch was responsible for the last 12 volumes. He also finished the chapter on spiders in ''Faunae insectorum germanicae initia oder Deutschlands Insecten'' lements of the insect fauna of Germanya work by Georg Wolfgang Franz Panzer (1755–1829). He also co-authored, with Georg Karl Berendt, an important monograph ''Die im Bernstein befindlichen Myriapoden, Arachniden und Apteren der Vorwelt'' (1854) on arachnids, myriapods, and wingless insects in amber based on material in Berendt's collection, now held in the Muse ...

Eugène Simon
Eugène Louis Simon (; 30 April 1848 – 17 November 1924) was a French naturalist who worked particularly on insects and spiders, but also on birds and plants. He is by far the most prolific spider taxonomist in history, describing over 4,000 species. Work on spiders His most significant work was ''Histoire Naturelle des Araignées'' (1892–1903), an encyclopedic treatment of the spider genera of the world. It was published in two volumes of more than 1000 pages each, and the same number of drawings by Simon. Working at the Muséum National d'Histoire Naturelle in Paris, it took Simon 11 years to complete, while working at the same time on devising a taxonomic scheme that embraced the known taxa. Simon described a total of 4,650 species, and as of 2013 about 3,790 species are still considered valid. The International Society of Arachnology offers a Simon Award recognising lifetime achievement. The Eocene fossil spider species '' Cenotextricella simoni'' was named in his ...

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] |
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 ...
