Black-backed Antshrike
The black-backed antshrike (''Thamnophilus melanonotus'') is a species of bird in the family Thamnophilidae. It is found in Colombia and Venezuela, where its natural habitat is subtropical or tropical dry forests. The black-backed antshrike was described by the English zoologist Philip Sclater in 1855 and given the binomial name ''Thamnophilus melanonotus''. It was subsequently placed in the genus '' Sakesphorus''. A molecular phylogenetic study published in 2007 found that ''Sakesphorus'' was polyphyletic and that three species including the black-backed antshrike were embedded within a clade containing members of '' Thamnophilus''. The black-backed antshrike was therefore moved back to its original genus.

Philip Sclater
Philip Lutley Sclater (4 November 1829 – 27 June 1913) was an England, English lawyer and zoologist. In zoology, he was an expert ornithologist, and identified the main zoogeographic regions of the world. He was Secretary of the Zoological Society of London for 42 years, from 1860–1902. Early life Sclater was born at Tangier Park, in Wootton St Lawrence, Hampshire, where his father William Lutley Sclater had a country house. George Sclater-Booth, 1st Baron Basing was Philip's elder brother. Philip grew up at Hoddington House where he took an early interest in birds. He was educated in school at Twyford and at thirteen went to Winchester College and later Corpus Christi College, Oxford where he studied scientific ornithology under Hugh Edwin Strickland. In 1851 he began to study law and was admitted a Fellow of Corpus Christi College. In 1856 he travelled to America and visited Lake Superior and the upper St. Croix River (Wisconsin–Minnesota), St. Croix River, cano ...

Sakesphorus
''Sakesphorus'' is a genus of passerine birds in the antbird family, Thamnophilidae. The genus ''Sakesphorus'' was erected by the British ornithologist Charles Chubb in 1918 with the black-crested antshrike as the type species. The name of genus is from the Ancient Greek ''sakesphoros '' "shield-bearing", from ''sakos'' "shield" and ''-phoros'' "-bearing". The genus contains the following species: * Black-crested antshrike (''Sakesphorus canadensis'') * Glossy antshrike The glossy antshrike (''Sakesphorus luctuosus'') is a species of bird in the family Thamnophilidae, the antbirds. The glossy antshrike is endemic to Brazil, and can only be found near the Amazon River's outlet at the western Atlantic Ocean, and m ...

Birds Described In 1855
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

Thamnophilus
''Thamnophilus'' is a genus of antbird in the antbird family, Thamnophilidae. The species in this genus are commonly known as antshrikes. They are insectivores that feed by gleaning prey from foliage and are found in the Neotropics. The genus ''Thamnophilus'' was introduced by the French ornithologist Louis Vieillot in 1816. The name combines the Ancient Greek words ''thamnos'' "bush" and ''philos'' "loving". The type species was subsequently designated as the barred antshrike. The genus contains the following species: * Collared antshrike, ''Thamnophilus bernardi'' * Black-backed antshrike, ''Thamnophilus melanonotus'' * Band-tailed antshrike, ''Thamnophilus melanothorax'' * Barred antshrike, ''Thamnophilus doliatus'' * Chapman's antshrike, ''Thamnophilus zarumae'' * Bar-crested antshrike, ''Thamnophilus multistriatus'' * Chestnut-backed antshrike, ''Thamnophilus palliatus'' * Lined antshrike, ''Thamnophilus tenuepunctatus'' * Black-hooded antshrike, ''Thamnophilus br ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Binomial Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth.
