The concern the reviewer mentions here was also one of our main conclusions for the article. Apparently we did not formulate it well enough. It has thus been reformulated to: “However an accurate taxonomy can never be achieved by the use of a barcoding method only, since it is based on nucleotide substitutions of a single gene. Accurate classification always requires an integrative taxonomy effort R2 including characteristics from ecology, morphology and physiology, as already previously suggested for prokaryotes [9,28,29,45], and as it is becoming common also for animal taxonomy (e.g., [53,54]).”
We hope that now both reviewers, and all other potential readers, will not be misled by our approach.
