Note: a species group defined as a taxon, rather than as a category of ranks, has an unofficial rank, one of several such ranks between the subgenus and species levels sometimes used by zoologists in taxa with many species; see Taxonomic rank.) The name-bearing type of a species-group taxon (hereafter "species" for brevity) is an actual ...
The binomial name often reflects limited knowledge or hearsay about a species at the time it was named. For instance Pan troglodytes, the chimpanzee, and Troglodytes troglodytes, the wren, are not necessarily cave-dwellers. Sometimes a genus name or specific descriptor is simply the Latin or Greek name for the animal (e.g. Canis is Latin for ...
The syntypes collectively constitute the name-bearing type." (Glossary of the zoological Code [ 1 ] ). Historically, it was common to describe a new species or subspecies from several syntypes without designating a holotype, but this practice is generally frowned upon by modern taxonomists, and most are gradually being replaced by lectotypes.
The term "type species" is regulated in zoological nomenclature by article 42.3 of the International Code of Zoological Nomenclature, which defines a type species as the name-bearing type of the name of a genus or subgenus (a "genus-group name"). In the Glossary, type species is defined as
In many cases species-group names have no type specimens, or they are lost. In those cases the application of the species-group name is usually based on common acceptance. If there is no common acceptance, there are provisions in the Code to fix a name-bearing type specimen that is binding for users of that name.
This means the species a binomial name refers to can be clearly identified, as compared to the common names of species which are usually different in every language. [6] However, establishing that two names actually refer to the same species and then determining which has priority can sometimes be difficult, particularly if the species was ...
In botanical nomenclature, "name" always refers to the whole name (of a species or otherwise), whereas in zoological nomenclature it can refer to either part of the binomen. Thus Hedera helix (common ivy, English ivy) is the name of the species; Hedera is the name of the genus; but helix is called the specific epithet, not the specific name. [2]
Used for species that resemble previously named species. Examples: Paranthodon ("nearly flower tooth"); Pararhabdodon ("near fluted tooth"); Parasaurolophus ("near lizard crest")-pelta: Pronunciation: /pɛltə:/ Origin: Ancient Greek: πέλτη (péltē). Meaning: shield. Frequently used for ankylosaurs.
