"a name without a proper description" |
a name of unknown or doubtful application |
1 |
a naked name, a name that, if published before 1931, was not accompanied by a description, definition, or indication, or if published after 1930, is not accompanied by a statement that purports to give characters differentiating the taxon; or is not accompanied by a definite bibliographic reference to such a statement; or is not proposed expressly as a replacement for a pre-existing available name. |
|
2 |
A name that was not properly associated with actual specimens. |
A name used without sufficient information so that later authors are unable to determine what taxon was meant. |
3 |
"naked name": generic name lacking a description and/or a type specimen for its type species; indicated name, when given, is the scientific name subsequently applied to the material; |
"doubtful name": generic name the type specimen of whose type species is too incomplete to be distinguished from like material belonging to at least two otherwise distinct species; a nomen dubium genus may be a synonym of another genus, but its known material is not considered complete enough to formalize such synonymy; |
ICZN art. 75 |
identity of a nominal species-group taxon cannot be determined from its existing name-bearing type |
|
4 |
a name, published without a description or diagnosis |
A name whose application is uncertain; the confusion being derived from an incomplete or confusing description |
Naar persoonlijke ervaring: Een nomen dubium gebruikt men als het type-exemplaar is onderzocht en ondiagnostisch bevonden. Een nomen nudum gebruikt men als het type-exemplaar om een of andere reden ontbreekt (want dan kan je het ook niet achteraf beschrijven).
