|
Domain | Subkingdom | Regnum |
In biological taxonomy, kingdom or regnum is a taxonomic rank in either (historically) the highest rank, or (in the new three-domain system) the rank below domain. Each kingdom is divided into smaller groups called phyla (or in some contexts these...

|
Kingdom | Superregnum |
In biological taxonomy, a domain (also superregnum, superkingdom, or empire) is the highest taxonomic rank of organisms, higher than a kingdom. According to the three-domain system of Carl Woese, introduced in 1990, the Tree of Life consists of...

| x Class |
|
Superclass | Subclass | Classis |
In biological classification, class (Latin: classis) is
The composition of each class is determined by a taxonomist. Often there is no exact agreement, with different taxonomists taking different positions. There are no hard rules that a taxonomist...

Superorder | Suborder | Ordo |
In scientific classification used in biology, the order (Latin: ordo) is
The Latin suffix -(i)formes meaning "having the form of" is used for the scientific name of orders of birds and reptiles, but not for those of mammals and invertebrates.

A genus is
The term comes from Latin genus "descent, family, type, gender" (plurals: genera), cognate with Greek: γένος - genos, "race, stock, kin".
Like for the other well-known taxonomic ranks, mentioned above, there is an immediately lower rank,...

| x Subphylum | Phylum | Superclass | Subphylum |
In life, a subphylum is a taxonomic rank intermediate between phylum and superclass. The rank of subdivision in plants and fungi is equivalent to subphylum.
Not all phyla are divided into subphyla. Those that are include:

| x Phylum |
|
Kingdom | Subphylum | Phylum |
In biology, a phylum (plural: phyla) is a taxonomic rank above Kingdom and below Class. "Phylum" is equivalent to the botanical term division.
Although a phylum is often spoken of as if it were a hard and fast entity, no satisfactory definition of a...

In biology, a subgenus is a taxonomic rank directly below genus. See rank (botany) and rank (zoology).
