Bifurcitus Ducalis
''Bifurcitus ducalis'', formerly ''Megadytes ducalis'', is a species of water beetle in the family Dytiscidae. It is the largest species in the family. Until recently, the species was only known from a single specimen that was collected in the 19th century from Brazil, but more specimens, also collected in the 19th century from Brazil, were discovered in 2019. Although listed as extinct by the IUCN, the limited studies conducted on water beetles in Brazil means that it might still survive. History The first specimen of ''B. ducalis'' was collected in the 19th century from an unknown locality in Brazil and is kept at the Natural History Museum, London. Rumors indicated it was found in the bottom of a canoe in the Amazon. In 2019, a study reported 10 additional specimens (including the first female of the species), all collected in the late 19th century, discovered incidentally in the National Museum of Natural History of France. While the original holotype lacked any exact locati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Beetles Described In 1882
Beetles are insects that form the order Coleoptera (), in the superorder Holometabola. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described arthropods and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. However, the number of beetle species is challenged by the number of species in dipterans (flies) and hymenopterans (wasps). Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids ...

Extinct Animals Of Brazil
Extinction is the termination of an organism by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. As a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, and mammoths. Through evolution, species arise through the process of speciation. Species become extinct when they are no longer able to survive in changing conditions or against superior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerrado
The Cerrado () is a vast ecoregion of Tropics, tropical savanna in central Brazil, being present in the states of Goiás, Mato Grosso do Sul, Mato Grosso, Tocantins, Maranhão, Piauí, Bahia, Minas Gerais, São Paulo (state), São Paulo, Paraná (state), Paraná and the Federal District (Brazil), Federal District. The core areas of the Cerrado biome are the Brazilian highlands – the ''Planalto''. The main habitat types of the Cerrado consist of forest savanna, wooded savanna, park savanna and grass, gramineous-woody savanna. The Cerrado also includes savanna wetlands and gallery forests. The second largest of Biomes in Brazil, Brazil's major habitat types, after the Amazon rainforest, Amazonian rainforest, the Cerrado accounts for a full 21 percent of the country's land area (extending marginally into Paraguay and Bolivia). About 75% of the Cerrado’s 2 million km2 is privately owned. Vast amounts of research have shown that the Cerrado is one of the richest of all tropi ...

Megadytes Magnus
''Megadytes'' is a genus of diving beetles in the family Dytiscidae. They are found in slow-moving or static freshwater habitats in the Neotropics. The adult beetles measure about long depending on the exact species and the largest is also the largest in the family (together with certain ''Dytiscus''). Species Following reclassification in 2024, ''Megadytes'' now contains two described species: * ''Megadytes latus'' (Fabricius, 1801) * ''Megadytes parvus ''Megadytes'' is a genus of diving beetles in the family Dytiscidae.

Hypocephalus Armatus
''Hypocephalus armatus'', the mole beetle, is a species of beetle in the family Vesperidae. It is the only species in the genus ''Hypocephalus''. Both the genus and species were first described by Anselme Gaëtan Desmarest in 1832. It is found in Brazil and is popular in museums and collections for its curiosity value and adaptations to digging in soil that make them appear outwardly similar to the mole crickets. Description ''Hypocephalus armatus'' can reach a body length of about . This rare species has an evident sexual dimorphism, as the very strong legs of the males are more developed than in females. It is similar in appearance to a mole cricket through convergent evolution. In both sexes the flight wings are absent, the prothorax is ovoid and shiny black, the dark brown elytra are fused together and the hind legs are much heavier than the others and adapted for digging. Adult males can be found from November to March, usually after the rains, when they dig into the soil. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Museum Of Natural History, France
The French National Museum of Natural History ( ; abbr. MNHN) is the national natural history museum of France and a of higher education part of Sorbonne University. The main museum, with four galleries, is located in Paris, France, within the Jardin des Plantes on the left bank of the River Seine. It was formally founded in 1793, during the French Revolution, but was begun even earlier in 1635 as the royal garden of medicinal plants. The museum now has 14 sites throughout France. Since the 2014 reform, it has been headed by a chairman, assisted by deputy managing directors. The Museum has a staff of approximately 2,350 members, including six hundred researchers. It is a member of the national network of naturalist collections (RECOLNAT).

Natural History Museum, London
The Natural History Museum in London is a museum that exhibits a vast range of specimens from various segments of natural history. It is one of three major museums on Exhibition Road in South Kensington, the others being the Science Museum (London), Science Museum and the Victoria and Albert Museum. The Natural History Museum's main frontage, however, is on Cromwell Road. The museum is home to life and earth science specimens comprising some 80 million items within five main collections: botany, entomology, mineralogy, palaeontology and zoology. The museum is a centre of research specialising in Taxonomy (biology), taxonomy, identification and conservation. Given the age of the institution, many of the collections have great historical as well as scientific value, such as specimens collected by Charles Darwin. The museum is particularly famous for its exhibition of dinosaur skeletons and ornate architecture—sometimes dubbed a ''cathedral of nature''—both exemplified by the ...
