Subject: Homonyms Between Preexisting Codes
It seems to me that Rule 11.8 is ambiguous when it comes to homonymic= taxa belonging to different preexisting codes (e.g., ICZN and ICBN). (emphasis added) "11.8. In the interest of consistency with the preexisting codes, IT = WOULD BE DESIRABLE for a clade whose name is converted from a genus name under= a preexisting code, or is derived from the stem of a genus name, TO INC= LUDE THE TYPE OF THE GENUS NAME. Therefore, when a clade name is converted fro= m a preexisting genus name or is a new or converted name derived from the= stem of a genus name, the definition of the clade name must use the type specie= s of that genus name at the time of establishment as an internal specifier." In the case of homonymic taxa, it is not clear which type species sho= uld be included. For example, in converting _Ficus_, should the required int= ernal specifier be the type of _Ficus_ Linnaeus 1753 [ICBN] (_Ficus carica_= Linnaeus 1753; common fig tree) or of _Ficus_ R=F6ding 1798 [ICZN] (_Murex fic= us_ Linnaeus 1758; a snail)? I would think the older genus (_Ficus_ Linnaeus 1753) would be prefer= red, but this is not explicitly stated, as far as I can see (unless I missed s= omething). (This problem could be mirrored in higher taxa as well. For example, = "-idae" is both the ICZN suffix for a family and the ICBN suffix for a subclass;= it's possible that homonymous genera between the ICZN and ICBN could typif= y a family and a subclass, respectively, although I can't think of any examples = right now.) =3D=3D=3D=3D=3D =3D=3D=3D=3D=3D> T.
