Ah, but if you remove these attributes, especially at genus level, now you cannot distinguish between the following, as per my recent post regarding Decapoda real world homonymy instances:

Duncania Portell & Collins, 2004 (Decapoda: Leucosiidae), listed as valid in De Grave et al., 2009, cf. Duncania Koninck, 1872 (Cnidaria), also Duncania Pourtal├Ęs, 1874 (Cnidaria), and Duncania Bayle, 1879 (Mollusca) - at least one of which is probably valid

... not to mention Duncania H.G.L. Reichenbach, 1828 which is a genus in Magnoliophyta, currently considered a syn. of Asaphes A. P. de Candolle 1825, (which itself has the jun. homonym Asaphes K.P.J. Sprengel, 1827 in Botany, as well as Asaphes Walker, 1834, Asaphes Kirby, 1837 and Asaphes Turner, 1945 in Zoology...)

As I have hinted before and we encounter again above, this is a significantly non-trivial problem at genus level, even if minor at species level.
