Though a dissimilarity measure figures in the CVTree algorithm, it is not realistic to delineate taxa by using this measure at least for the time being.
I have noted some lack of scientific rigor according to: many wrong taxonomic names and typos, scarce figure legends, few comments about the missing branch lengths or bootstraps (! ), redundancy in text and figures and fragments which are really difficult to understand. Authors should pay attention to language, explanations and text organization.
