il n'y a pas illégitimité en cas d'indication d'un doute, cf. Art 52.2 Note 1 : "The inclusion, with an expression of doubt, of an element in a new taxon, e.g. the citation of a name with a question mark, or in a sense that excludes one or more of its potential type elements, does not make the name of the new taxon nomenclaturally superfluous. " (V. Malécot, com. pers.)
