Delturinae
The Delturinae are a subfamily of catfishes (order Siluriformes) of the family Loricariidae, including two genera, '' Delturus'' and '' Hemipsilichthys''. This group is sister to all other loricariids except ''Lithogenes''. The geographical distribution of Delturinae, exclusively on the southeastern Brazilian Shield The Amazonian Craton is a geologic province located in South America. It occupies a large portion of the central, north and eastern part of the continent and represents one of Earth's largest cratonic regions. The Guiana Shield and Central Brazi ..., indicates southeastern Brazil acts as either a refugium for basal loricariid taxa or a point of origin for the Loricariidae. Both genera can be separated from all other loricariids by the presence of a postdorsal ridge made up of raised, median, unpaired plates and the presence of an adipose fin membrane. ''Hemipsilichthys'' can be separated from ''Delturus'' by not having the anterior plates of the ridge contacting t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loricariidae
The Loricariidae is the largest family of catfish (order Siluriformes), with 92 genera and just over 680 species. Loricariids originate from freshwater habitats of Costa Rica, Panama, and tropical and subtropical South America. These fish are noted for the bony plates covering their bodies and their suckermouths. Several genera are sold as " plecos", notably the suckermouth catfish, '' Hypostomus plecostomus'', and are popular as aquarium fish. Common names Members of the family Loricariidae are commonly referred to as loricariids, suckermouth armoured catfishes, or armoured catfish. The name " plecostomus", and its shortened forms "pleco" and "plec", are used for many Loricariidae, since ''Plecostomus plecostomus'' (now called '' Hypostomus plecostomus'') was one of the first loricariid species imported for the fish-keeping hobby. Some loricariids are not normally considered "plecostomus", such as '' Farlowella'' catfish. In their native range, these fish are known as '' ...

Hemipsilichthys
''Hemipsilichthys'' is a genus of catfishes belonging to the family Loricariidae. These wide-mouthed freshwater catfishes are restricted to southeast Brazil in the Paraíba do Sul, Perequê-Áçu and Taquari river basins. ''Hemipsilichthys'', along with ''Delturus'', form a clade (Delturinae). In these two genera, members have a ridge behind their dorsal fin and an adipose fin membrane. However, in ''Hemipsilichthys'', the dorsal fin membrane and most anterior plate of the adipose fin do not touch, while they do in ''Delturus''. Species There are currently three recognized species in this genus: Additional species were formerly placed in this genus, but these are now placed in ''Pareiorhaphis''. * ''Hemipsilichthys gobio'' ( Lütken, 1874) * ''Hemipsilichthys nimius'' Pereira, Reis, Souza & Lazzarotto, 2003 * ''Hemipsilichthys papillatus ''Hemipsilichthys papillatus'' is a species of loricariid catfish endemic to Brazil, where it is restricted to the Rio Preto, a tributar ...

Subfamily
In biological classification, a subfamily ( Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae".

Catfish
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus '' Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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 of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Cladistics
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a ' grade', which are fruitless to precisely delineate, especially when including extinct species. ...

Lithogenes
''Lithogenes'' is a genus of South American catfish of the family Loricariidae. It is the only genus within the subfamily Lithogeneinae. Taxonomy ''Lithogenes'' is the only genus within the subfamily Lithogeneinae. This genus and subfamily, the most Basal (phylogenetics), basal group in Loricariidae, is the cladistics, sister group to the rest of the family.

Brazilian Highlands
The Brazilian Highlands or Brazilian Plateau ( pt, Planalto Brasileiro) are an extensive geography, geographical region, covering most of the eastern, southern and central portions of Brazil, in all approximately half of the country's land area, or some 4,500,000 km2 (1,930,511 sq mi). In addition, the vast majority of Brazil's population (190,755,799; ''2010 census'') lives in the highlands or on the narrow coastal region immediately adjacent to it. Ancient basaltic lava flows gave birth to much of the region. However, the time of dramatic geophysics, geophysical activity is long past, as there is now no earthquake, seismic or volcano, volcanic activity. Erosion has also played a large part in shaping the Highlands, forming extensive sedimentary deposits and wearing down the mountains. The Brazilian Highlands are recognized for the great diversity to be found there: within the region there are several different biomes, vastly different climate, climatic conditions, many typ ...

Taxa Named By Roberto Esser Dos Reis
In biology, a taxon ( back-formation from '' taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
