Question

what is nomen nudum and nomen dubium​

Answer 1

Answer:

Nomen Nudum

: a proposed taxonomic name that is invalid because the group designated is not described or illustrated sufficiently for recognition, that has no nomenclatural status, and that consequently can be used as though never previously proposed.

Nomen Dubium

: a taxonomic name that cannot be assigned with certainty to any taxonomic group because the description is insufficient for identification and the original specimens no longer exist.

Explanation:

Nomen Nudum :-

("naked name"; plural nomina nuda)

is a designation which looks exactly like a scientific name of an organism, and may have originally been intended to be a scientific name, but fails to be one because it has not (or has not yet) been published with an adequate description (or a reference to such a description). This makes it a "bare" or "naked" name, one which cannot be accepted as it stands.

Nomen Dubium :-

In zoological nomenclature, a nomen dubium (Latin for "doubtful name", plural nomina dubia) is a scientific name that is of unknown or doubtful application.

In bacteriological nomenclature, nomina dubia may be placed on the list of rejected names by the Judicial Commission. The meaning of these names is uncertain
