Name-bearing Type
Under the ''International Code of Zoological Nomenclature'' (''Code''), the name-bearing type or onomatophore is the biological type that determines the application of a name. Each animal taxon regulated by the ''Code'' at least potentially has a name-bearing type.''Code'', Article 61.1 The name-bearing type can be either a type genus (family (biology), family group),''Code'', Article 63 type species (genus (biology), genus group),''Code'', Article 67.1 or one or more type specimens (species group).''Code'', Article 72.1.2 For example, the name ''Mabuya maculata'' (Gray, 1839) has often been used for the Noronha skink (currently ''Trachylepis atlantica''), but because the name-bearing type of the former, a lizard preserved in the Muséum national d'histoire naturelle in Paris, does not represent the same species as the Noronha skink, the name ''maculata'' cannot be used for the latter.

International Code Of Zoological Nomenclature
The International Code of Zoological Nomenclature (ICZN) is a widely accepted Convention (norm), convention in zoology that rules the formal scientific name, scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its formal author, the International Commission on Zoological Nomenclature (which shares the acronym "ICZN"). The rules principally regulate: * How names are correctly established in the frame of Binomial nomenclature, binominal nomenclature * How to determine whether a given name is Available name, available * Which available name must be used in case of name conflicts (Valid name (zoology), valid name) * How scientific literature must cite names Zoological nomenclature is independent of other systems of nomenclature, for example botanical nomenclature. This implies that animals can have the same generic names as plants (e.g. there is a genus ''Abronia (other), Abronia'' in both animals and plants). The rules and re ...

Tribe (taxonomy)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxa ranked above species are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the genus na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomic Rank
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a ''taxon'') in a hierarchy that reflects evolutionary relationships. Thus, the most inclusive clades (such as Eukarya and Animalia) have the highest ranks, whereas the least inclusive ones (such as ''Homo sapiens'' or ''Bufo bufo'') have the lowest ranks. Ranks can be either relative and be denoted by an indented taxonomy in which the level of indentation reflects the rank, or absolute, in which various terms, such as species, genus, Family (biology), family, Order (biology), order, Class (biology), class, Phylum (biology), phylum, Kingdom (biology), kingdom, and Domain (biology), domain designate rank. This page emphasizes absolute ranks and the rank-based codes (the International Code of Zoological Nomenclature, Zoological Code, ...

Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Trachylepis Maculata Head
''Trachylepis'' is a skink genus in the subfamily Mabuyinae found mainly in Africa. Its members were formerly included in the "wastebin taxon" ''Mabuya'', and for some time in ''Euprepis''. As defined today, ''Trachylepis'' contains the clade of Afro-Malagasy mabuyas. The genus also contains a species from the Brazilian island of Fernando de Noronha, ''Trachylepis atlantica, T. atlantica'', and may occur in mainland South America with ''Trachylepis tschudii'' and ''Trachylepis maculata'', both poorly known and enigmatic. The ancestors of ''T. atlantica'' are believed to have Oceanic dispersal, rafted across the Atlantic from Africa during the last 9 million years. The Genus, generic name ''Trachylepis'' literally means "rough-scaled", referring to the fact that most of the species, though superficially smooth-scaled, have three or more slight longitudinal keels on their dorsal scales. Species The following species are recognized as being valid (listed alphabetically by Specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mabuya
''Mabuya'' is a genus of long-tailed skinks, lizards in the family Scincidae. The genus is restricted to species from various Caribbean islands. Out of 26 recognized species, six species are only found in Caribbean islands. Species in the genus ''Mabuya'' are primarily carnivorous, though many are omnivorous. The genus is viviparous, having a highly evolved placenta that resembles that of eutherian mammals. Formerly, many Old World species were placed here, as ''Mabuya'' was a kind of "wastebasket taxon". These Old World species are now placed in the genera '' Chioninia'', ''Eutropis'', and ''Trachylepis''. Under the older classification, the New World species were referred to as "American mabuyas", and as of 2024 include the genera '' Alinea'', '' Aspronema'', '' Brasiliscincus'', '' Capitellum'', '' Copeoglossum'', '' Maracaiba'', '' Marisora'', and '' Varzea''. Most species in this genus are feared to be possibly extinct due to introduced predators. Species Listed alphabeti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lygosoma Punctatum
''Lygosoma'' is a genus of lizards, commonly known as supple skinks or writhing skinks, which are members of the family Scincidae. ''Lygosoma'' is the type genus of the subfamily Lygosominae. The common name, writhing skinks, refers to the way these stubby-legged animals move, snake-like but more slowly and more awkwardly. Geographic range Species of ''Lygosoma'' are found in India to southeast Asia. Taxonomy In the late 19th and early 20th century, ''Lygosoma'' was used as a " wastebin taxon", to which almost every newly described skink was assigned. Which specific species are contained within this genus is controversial because of its unresolved historic relation to two other closely related genera: ''Mochlus'' and ''Lepidothyris.'' Currently, there are 16 known species in ''Lygosoma'', 15 known species in ''Mochlus'', and three known species in ''Lepidothyris''. However, some species under the latter two genera are often listed under ''Lygosoma'', and ''Lygosoma'' was re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skink
Skinks are a type of lizard belonging to the family (biology), family Scincidae, a family in the Taxonomic rank, infraorder Scincomorpha. With more than 1,500 described species across 100 different taxonomic genera, the family Scincidae is one of the most diverse families of lizards. Skinks are characterized by their smaller legs in comparison to typical lizards and are found in different habitats except arctic and subarctic regions. Etymology The word ''skink'', which entered the English language around 1580–1590, comes from classical Greek and Latin , names that referred to various specific lizards. Description Skinks look like lizards of the family Lacertidae (sometimes called ''true lizards''), but most species of skinks have no pronounced neck and relatively small legs. Several genera (e.g., ''Typhlosaurus'') have no limbs at all. This is not true for all skinks, however, as some species such as the Tribolonotus gracilis, red-eyed crocodile skink have a head that is ve ...

Ichnotaxon
An ichnotaxon (plural ichnotaxa) is "a taxon based on the fossilized work of an organism", i.e. the non-human equivalent of an artifact. ''Ichnotaxon'' comes from the Ancient Greek (''íchnos'') meaning "track" and English , itself derived from Ancient Greek (''táxis'') meaning "ordering".Definition o'ichno'at dictionary.com. Ichnotaxa are names used to identify and distinguish morphologically distinctive ichnofossils, more commonly known as trace fossils (fossil records of lifeforms' movement, rather than of the lifeforms themselves). They are assigned genus and species ranks by ichnologists, much like organisms in Linnaean taxonomy. These are known as ichnogenera and ichnospecies, respectively. "Ichnogenus" and "ichnospecies" are commonly abbreviated as "igen." and "isp.". The binomial names of ichnospecies and their genera are to be written in italics. Most researchers classify trace fossils only as far as the ichnogenus rank, based upon trace fossils that resemble eac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subgenus
In biology, a subgenus ( subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN or ICNafp) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all tho ...
