The problem with using genes to define species is that you have to decide a priori that some % divergence defines a species, rather than reproductive isolation (which will give rise to distinct morphologies). It is entirely unclear what % that should be and there is no natural cutoff. Genes are nice because they can resolve lineage relationships well, but assigning a rank to those relationships isn't any easier with genetic data than with morphological data.
