Article 18. Inappropriate and tautonymous names
The availability of a name is not affected by inappropriateness or tautonymy [Art. 23.3.7].
Examples. Names such as Polyodon, Apus, albus or sinensis are not to be rejected because of a claim that they denote a character or distribution not possessed by the taxon. Species-group names such as bison in Bison bison and troglodytes in Troglodytes troglodytes troglodytes are not to be rejected because of tautonymy.
