A genus refers to a principle taxonomic classification, which ranks below family and above species.
Thus in the examples above, the genus In zoological usage, taxonomic names, including those of genera, are classified as "Consequently, there will be more available names than valid names at any point in time, which names are currently in use depending on the judgement of taxonomists in either combining taxa described under multiple names, or splitting taxa which may bring available names previously treated as synonyms back into use. For instance, the lizard genus Taxonomic rank used in the biological classification of living and fossil organisms, and viruses"Genera" redirects here. For the operating system, see

The botanical equivalent of zoology's "available name" is a A particular genus name may have zero to many synonyms, the latter case generally if the genus has been known for a long time and redescribed as new by a range of subsequent workers, or if a range of genera previously considered separate taxa have subsequently been consolidated into one. A genus is a group of related plants.
Definition of genus. In addition to species and genera, Linnaeus also recognized other classificatory groups, or taxa (singular taxon), which are still used; namely, order, class, and kingdom, to which have… The scientific name (or the scientific epithet) of a genus is also called the As with scientific names at other ranks, in all groups other than viruses, names of genera may be cited with their authorities, typically in the form "author, year" in zoology, and "standard abbreviated author name" in botany.
Although all species within a genus are supposed to be "similar" there are no objective criteria for grouping species into genera.
"Unavailable" names in zoology comprise names that either were not published according to the provisions of the ICZN Code, or have subsequently been suppressed, e.g., incorrect original or subsequent spellings, names published only in a thesis, and generic names published after 1930 with no type species indicated.In botany, similar concepts exist but with different labels.
…indicates the larger category, or genus, to which chimpanzees belong; the second word is the name of the species within the genus. 1 : a class, kind, or group marked by common characteristics or by one common characteristic specifically : a category of biological classification ranking between the family and the species, comprising structurally or phylogenetically (see phylogenetic sense 2) related species or an isolated species exhibiting unusual differentiation, and being designated by a Latin or latinized …

There is much debate among zoologists whether large, species-rich genera should be maintained, as it is extremely difficult to come up with identification keys or even character sets that distinguish all species. See Table at taxonomy. Genus, plural genera, biological classification ranking between family and species, consisting of structurally or phylogenetically related species or a single isolated species exhibiting unusual differentiation (monotypic genus).

For example, the A list of generic homonyms (with their authorities), including both available (validly published) and selected unavailable names, has been compiled by the The numbers of either accepted, or all published genus names is not known precisely; Rees et al., 2020 estimate that approximately 310,000 accepted names (valid taxa) may exist, out of a total of c. 520,000 published names (including synonyms) as at end 2019, increasing at some 2,500 published generic names per year.Totals for both "all names" and estimates for "accepted names" as held in the The cited ranges of uncertainty arise because IRMNG lists "uncertain" names (not researched therein) in addition to known "accepted" names; the values quoted are the mean of "accepted" names alone (all "uncertain" names treated as unaccepted) and "accepted + uncertain" names (all "uncertain" names treated as accepted), with the associated range of uncertainty indicating these two extremes.
In binomial nomenclature, the name of the genus comes first, and it is followed by the name of the species.

For example, Periplaneta is the genus of the American cockroach, and comes from the Greek for wandering about.
For example, the Within the same kingdom, one generic name can apply to one genus only.
The genus is the generic name that includes closely related species; the gray wolf, for example, is classified as Canis lupus and is a close relative of the coyote found in North America and designated as Canis latrans, their systematic relation indicated by their sharing the same genus name, Canis. However, many names have been assigned (usually unintentionally) to two or more different genera. Hence, many taxonomists argue in favor of breaking down large genera.
