The tautonym ( ancient Greek τὸ αὐτό tò autó 'the same' and ὄνομα ónoma 'the name') is the same name in biological nomenclature that is used for both a genus and an included species, e.g. B. Salamandra salamandra .
The International Rules for Zoological Nomenclature allow tautonyms. In zoology, a tautonym is therefore the prerequisite for a nominotypical taxon with triple use of the name, such as Bufo bufo bufo .
The International Code of Nomenclature for algae, fungi and plants includes Art. 23.4 the use of Tautonymen in botany, so that such a name can not be published valid. A small difference is enough, however; for example, Ziziphus zizyphus is permitted.
