What I referred to were two issues: (1) the scientifically questionable tactic of ‘barcoding,’ to which the authors speak, not just as a keyword, especially when all of us do not agree on what we mean by the term ‘species’ and the matter of following the requirement of total evidence; and (2) it appeared that additional characters, not just pigmentation, are known yet were not considered in the analysis: ‘Amino acid sequences from these short peptides are substantially different between closely related species (Kim & Kang 1998) and even among paralogues of this serine protease family within a species (Moser et al.1998).’ While there might be no internal anatomical distinctions, there are also no other characters to be considered outside of nucleotides? I interpreted statements in the paper to suggest the contrary.
