Review History
Integrative taxonomy of Metrichia Ross (Trichoptera: Hydroptilidae: Ochrotrichiinae) microcaddisflies from Brazil: descriptions of twenty new species

Thank you very much - the revisions were done well, and this manuscript is now ready to be published.

I apologize for confusion with the last version, and have read over this new version. In short, it is much better, and almost acceptable for publication.

Please note there are still some small edits, please see the attached PDF file and make sure these changes are done. In particular, please ensure 'genitalia' and 'data' are used as plural (watch for verb agreement).

My decision is 'minor revision' with the emphasis on minor.

Unfortunately, the paper still needs some English work. I understand you had someone proofread the paper for you, but if you look at the attachment, you can see my edits on your Introduction indicate that work is still needed (note I have not thoroughly checked the rest of your paper). While some of my edits may be considered as stylistic changes, there are still many basic mistakes in grammar that simply cannot be in a published paper. I realize your paper is very long, but the onus on having the English up to acceptable levels is on the authors. As this work is taxonomic, it is even more important to have clear and unambiguous English throughout the text to remove any chance of future confusion from readers.

Based on this, my decision is 'minor revision'.

Dear authors,

I have gone over your paper and rebuttal letter, and feel you have answered the large majority of the comments very well. Thus, as far as scientific validity and commentary goes, I feel your paper is acceptable in the current form.

However, in reviewing the English of the paper, I have noticed there are many corrections needed. I have gone over the Introduction (please see attached file) and made edits, but feel that the whole paper needs to be completely checked once by a native English speaker trained in biology before acceptance, as PeerJ does not offer such editing services, nor is this the job of the editor.

This is from the 'Acceptance Criteria': "The article must be written in English using clear and unambiguous text and must conform to professional standards of courtesy and expression."

I am sorry I did not attach such edits in the previous rounds of reviews - I usually like to do such checks on the "near-final" versions after the authors' revisions, but can see from this experience it would be worthwhile for me to do this in the initial round of reviews.

Therefore, as some minor work (English) is needed, my decision is "Minor revisions".

Both reviewers were generally positive about your manuscript, and both offered very constructive and helpful comments (see their annotated manuscripts). Based on this, I have reached the decision of 'Minor Revisions'.
