Poecilotheria Regalis10
''Poecilotheria'' is a genus of tarantulas native to India and Sri Lanka. It was first described by Eugène Louis Simon in 1885. They are arboreal tarantulas, commonly known as ornamental tarantulas, known for their vivid color patterns, fast movement, and potent venom compared to other tarantulas. all species are protected under CITES. The genus name is a combination of the Ancient Greek " poikilos" (), meaning "spotted", and therion" (), meaning "wild beast". Taxonomy The species belonging to ''Poecilotheria'' were first documented in 1734 by Dutch zoologist Albertus Seba, when he went to Sri Lanka. He published the new spiders he saw in his illustrations of the book ''Albertus Seba's Thesaurus'' under the name of ''Aranea maxima ceilonica'' (meaning ''big spider from Sri Lanka''). However, the most precise scientific explanation came in 1804 when Pierre Latreille described the spider as ''Mygale fasciata''. After about 40 years delay, in 1850, C.L. Koch revised the generic ...

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 ...

Poecilotheria Regalis
''Poecilotheria regalis'' is a species of arboreal tarantula and is found in parts of India. The common name for this spider is Indian ornamental tree spider, or simply Indian ornamental. It is one of the most popular arboreal tarantulas for amateur collectors. Their leg span sometimes exceeds 7 inches (18 cm). Name The name '' Poecilotheria'' is derived from Greek "poikilos" - spotted and "therion" - wild beast. Regalis refers to "royal". This whole genus of arboreal tarantulas exhibits an intricate fractal-like pattern on the abdomen. The spider's natural habitat is primarily Southeastern India. Behavior The behavior of ''P. regalis'' parallels that of many arboreal spiders. In the wild individuals live in holes in tall trees where they make asymmetric funnel webs. Their primary prey consists of various flying insects, which they seize in flight and paralyze. It is not unknown for the spiders of this genus to live communally when territory, i.e. the number of holes p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maxilla (arthropod Mouthpart)
In arthropods, the maxillae (singular maxilla) are paired structures present on the head as mouthparts in members of the clade Mandibulata, used for tasting and manipulating food. Embryologically, the maxillae are derived from the 4th and 5th segment of the head and the maxillary palps; segmented appendages extending from the base of the maxilla represent the former leg of those respective segments. In most cases, two pairs of maxillae are present and in different arthropod groups the two pairs of maxillae have been variously modified. In crustaceans, the first pair are called maxillulae (singular maxillula). Modified coxae at the base of the pedipalps in spiders are also called "maxillae", although they are not homologous with mandibulate maxillae. Myriapoda Millipedes In millipedes, the second maxillae have been lost, reducing the mouthparts to only the first maxillae which have fused together to form a gnathochilarium, acting as a lower lip to the buccal cavity and the man ...

Spider Anatomy
The anatomy of spiders includes many characteristics shared with other arachnids. These characteristics include bodies divided into two tagmata (sections or segments), eight jointed legs, no wings or antennae, the presence of chelicerae and pedipalps, simple eyes, and an exoskeleton, which is periodically shed. Spiders also have several adaptations that distinguish them from other arachnids. All spiders are capable of producing silk of various types, which many species use to build webs to ensnare prey. Most spiders possess venom, which is injected into prey (or defensively, when the spider feels threatened) through the fangs of the chelicerae. Male spiders have specialized pedipalps that are used to transfer sperm to the female during mating. Many species of spiders exhibit a great deal of sexual dimorphism. External anatomy Spiders, unlike insects, have only two main body parts ( tagmata) instead of three: a fused head and thorax (called a cephalothorax or prosoma) and a ...

Poecilotheria Bara
''Poecilotheria subfusca'', or the ivory ornamental, is a spider in the tarantula family, Theraphosidae.

Poecilotheria Hanumavilasumica
''Poecilotheria hanumavilasumica'', also known as the Rameshwaram ornamental, or Rameshwaram parachute spider, is a critically endangered species of tarantula. Distribution It was discovered in 2004 by Andrew Smith from a sacred grove of the Hanumavilasum Temple in Rameshwaram. It was initially thought to be endemic to the Ramanathapuram district in the state of Tamil Nadu, India, but has since been identified outside India in the Mannar District of Northern Sri Lanka. The close proximity of Mannar island to India suggests that the species may have dispersed over the land bridge between the two countries in the Pleistocene The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.

Poecilotheria Rajaei
''Poecilotheria rajaei'' is a tarantula in the genus ''Poecilotheria'' endemic to Sri Lanka. Genus The genus is native to Sri Lanka and India. The name ''Poecilotheria'' is derived from Greek: "poikilos", meaning spotted, and "therion", meaning wild beast.

Description The spider has a leg span of up to , has vivid yellow and gray piping on the first and fourth legs with a pink abdominal band. It prefers to live in old-growth trees, but is considered rare due to deforestation in its war-torn habitat and has taken to living in old buildings.

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.
