A new species is described and published. | New | New | New | New |
A species name is misapplied | Different, may match previously existing concept | New | ||
A species name is misspelled | New | New | ||
A new species is described using a junior primary homonym | New | New | New | New |
A replacement name is provided for a junior homonym | New | New | New | |
A revised description is given for a species | New | |||
A new species is described without qualifying under the rules of nomenclature | New | New | New | |
A previously known concept is given a formal description | New | New | Old datanym is deleted and new datanym created. | |
An incorrectly formed name receives a required emendation | New | New | ||
A name receives an unjustified emendation | New | New | ||
A species is transferred to a different genus. The spelling may change to match the gender of the genus. | New | Concepts for the two genera change, but not the concept for the species. | ||
A new subspecies is described separating what was an undivided species. | One new for the new subspecies | Two new for the two subspecies | Two new for the two subspecies | Previous datanym becomes the datanym of the nominotypical subspecies. (This preserves relationships with other tables.) Two new datanyms are created. |
A new subspecies is described from an area outside the range of what was an undivided species. | One new for the new subspecies | Two new for the two subspecies | Old concept moves to the nominotypical subspecies, one new for the other subspecies, one new for the species. | Previous datanym becomes the datanym of the nominotypical subspecies. Two new datanyms are created. |
A species is demoted to a subspecies in a species previously without subspecies. | Two new for the two subspecies | One new concept applies to the resulting species, two old concepts apply to the subspecies. | Previous datanym becomes the datanym of the nominotypical subspecies. The other subspecies retains its datanym. A new datanym is created for the species. | |
A subspecies is made a synonym of the only other subspecies. | Concepts for the two subspecies are discontinued. | |||
A subspecies is separated as a species different from the only other subspecies. | One new, two old discontinued | Concept for the previous species is discontinued. | Datanym for the species is no longer used. Datanym for the nominotypical subspecies becomes the datanym for the species. Datanym for the other subspecies remains. | |
A subspecies is separated as a species different from the other two subspecies. | One new | Concept for the old species is replaced by a new one. Concept for the subspecies separated remains unchanged. | Datanym for the old subspecies becomes the datanym for the new species. | |
A species group is described | Not applicable | Not applicable | New | New |
A form is descibed while forms were still permitted by the Code | New | New | New | New |
A form is described after forms were prohibited by the code | New | New | New | |
A form described when permitted is raised to subspecies rank. | New | |||
A form described when not permitted is raised to subspecies rank. | New | New | ||
A nomen dubium species is described. | New | New | Not applicable | New |
A nomen nudum is described and cannot be identified. | New | New | Not applicable | New |
A nomen nudum species is described and can be identified. | New | New if not an existing concept | New |
