Geospizopsis
''Geospizopsis'' is a genus of seed-eating birds in the tanager family Thraupidae that are commonly known as sierra finches. Taxonomy and species list The two species now placed in ''Geospizopsis'' were formerly placed in the genus '' Phrygilus''. A molecular phylogenetic study of the tanagers published in 2014 found that ''Phrygilus'' was polyphyletic. In the subsequent rearrangement to create monophyletic genera, the genus ''Geospizopsis'' was resurrected. It had originally been introduced in 1856 by the French naturalist Charles Lucien Bonaparte with ''Passerculus geospizopsis'' Bonaparte, 1853 as the type species. This taxon is now treated as a subspecies of the plumbeous sierra finch and has the trinomial name ''Geospizopsis unicolor geospizopsis''. The genus name combines ''Geospiza'', a genus introduced by John Gould in 1837, with the Ancient Greek Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1 ...

Thraupidae
The tanagers (singular ) comprise the bird family Thraupidae, in the order Passeriformes. The family has a Neotropical distribution and is the second-largest family of birds. It represents about 4% of all avian species and 12% of the Neotropical birds. Traditionally, the family contained around 240 species of mostly brightly colored fruit-eating birds. As more of these birds were studied using modern molecular techniques, it became apparent that the traditional families were not monophyletic. ''Euphonia'' and ''Chlorophonia'', which were once considered part of the tanager family, are now treated as members of the Fringillidae, in their own subfamily (Euphoniinae). Likewise, the genera ''Piranga'' (which includes the scarlet tanager, summer tanager, and western tanager), '' Chlorothraupis'', and '' Habia'' appear to be members of the cardinal family, and have been reassigned to that family by the American Ornithological Society.

Phrygilus Unicolor-Plumbeous Sierra Finch (Female)
''Phrygilus'' is a genus of mainly Andean seed-eating tanagers commonly known as sierra finches. Phrygilos means finch in Ancient Greek. Traditionally classified in the bunting and American sparrow family Emberizidae, more recent studies have shown them to belong in the Thraupidae. Taxonomy and species list The genus ''Phrygilus'' was introduced in 1844 by the German ornithologist Jean Cabanis with the grey-hooded sierra finch as the type species. The name is from the Ancient Greek ''phrugilos'', an unidentified bird mentioned by Aristophanes. The genus formerly included additional species. A molecular phylogenetic study published in 2014 found that the genus was highly polyphyletic and in the resulting reorganization members of the genus were moved to ''Geospizopsis'', '' Rhopospina'', ''Porphyrospiza ''Porphyrospiza'' is a genus of seed-eating South American birds in the tanager family Thraupidae.

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 ...

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

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.
