nomen novum

New name; a scientific name created to replace another scientific name for non-taxonomical reasons, e.g. when the name being replaced is a homonym.

nomenclature

Branch of taxonomy concerned with the application of scientific names to taxa, based on a particular classification scheme and in accordance with agreed international rules and conventions.

Used in 5 profiles

nominal taxon

A nomenclatural concept denoted by an available name used in an original description, and based, actually or potentially, upon its name-bearing type but having no defined taxonomic boundaries. Often used when the precise definition of a species or genus is unclear, such as when a name may refer to more than one taxon and is therefore in need of clarification.

patronym

In zoological nomenclature, a taxonomic name derived from the name of a person.

Used in 2 profiles

phylogeny

The evolutionary development and history of a species or other taxonomic group. May be based on morphology, molecular data, or both.

Used in 52 profiles

phylum

Taxonomic rank below kingdom and above class.

plesiomorphy

In cladistics, a character or trait shared by two or more taxonomic groups but derived from a remote or much earlier common ancestral form and therefore cannot be used to define a clade. Also known as an ancestral state and generally appears at the base level of a cladogram.

Used in 2 profiles

race

Genealogical line or lineage. Sometimes used as an infrasubspecific category, i.e., below the subspecies level, to refer to populations or individuals which are not given taxonomic names.

Used in 1 profile

scale count

Count of a given range of scales. Used in taxonomical studies to differentiate and identify taxa.

Used in 11 profiles

Used in 12 profiles

sensu stricto

Latin term meaning "in the strict sense". Used in conjunction with a taxonomic name to indicate exclusion of other names typically associated with it, or when referring to a taxon only in terms of its subordinate nominotypical taxon.

Containing a high number of species. Normally applied to a taxonomic group or specified geographical area.

Used in 177 profiles

subjective synonym

Any of two or more taxonomic names whose synonymy is a matter of individual opinion, i.e., they are based on multiple name-bearing types.

Used in 6 profiles

subspecies

Taxonomic rank below species, written in the form of a trinomen. Often applied to a geographically-separated population within a species that retains the capability to produce fertile offspring with other populations but may exhibit phenotypic differences.

Used in 78 profiles

symplesiomorphy

In cladistics, a character or trait shared by two or more taxonomic groups and derived from a remote or much earlier common ancestral form.

synapomorphy

In cladistics, a character or trait shared by two or more taxonomic groups and derived from a common ancestral form, whose ancestor in turn did not possess that trait.

Used in 42 profiles

synonym

In zoological nomenclature, any of two or more names of the same taxonomic rank used to denote the same taxon. Names referred to as synonyms are not usually valid in the current sense.

Used in 204 profiles
