Paper title: New insight into the genus Cladocroce (Porifera, Demospongiae) based on morphological and molecular data, with the description of two new species
The authors examined new sponge material collected in Vietnam and Indonesia and compared it with previous data using molecular and morphological features to determine the taxonomy of their sponges. The authors found three species belonging to the genus Cladocroce (Porifera, Demospongiae). Species delimitation models and phylogenetic approaches using three molecular markers (COI, 28S, and 18S-ITS1-5.8S-ITS2-28S) provided evidence that for Cladocroce burapha and Cladocroce pansinii sp. nov. and Cladocroce lamellata sp. nov., with the latter species being delimited by morphological data only. The authors provided a description for the new sponge species and noted a new record of Cladocroce aculeata in Indonesia. The authors concluded that C. burapha overlaps in distribution with Cladocroce pansinii in Vietnam and with Cladocroce lamellata in Indonesia, and suggested that the paratype of Cladocroce burapha should be transferred to Cladocroce pansinii.
All these reasons explain the relevance of the paper by Marco Bertolino and co-authors submitted to "Journal of Marine Science and Engineering".
General scores.
The data presented by the authors are original and significant. The study is correctly designed and the authors used appropriate sampling methods. In general, statistical analyses are performed with good technical standards. The authors conducted careful work that may attract the attention of a wide range of specialists focused on poriferan taxonomy.
Recommendations.
Figure 1 is of low resolution and is difficult to understand. The authors should increase both the resolution and font size.
The authors should change “Tab. “ to “Table” when referring to corresponding tables.
The resolution of Figure 4 needs to be increased.
In the reference list, all the Latin names should be italicized.

Dear Editorial Board of JMSE,
Our manuscript entitled: “New insight into the genus Cladocroce (Porifera,
Demospongiae) based on morphological and molecular data, with the description of two new species” submitted to JMSE: Journal of Marine Science and Engineering (Ms. Ref. No.: [JMSE] Manuscript ID: jmse-2362556) has now been revised attending to the reviewers’ comments and inquiries. We hope to have addressed satisfactorily the remarks from our referees. Our revised version consists on the present response letter (“'Response Letter to Reviewers'”), an annotated MARKED revised version of the MS that highlights changes made to the original version, in which edits are indicated by Word's track changes ("Revised Manuscript with Track Changes"), a Zip folder containing Figs. 1–6 in higher resolution, and a Zip folder with Supplementary material. As requested by Reviewer #3, we removed the paragraphs for molecular taxonomy results within each species section, and created a general section at the end of the morphological descriptions where we exposed all the molecular outcomes. Due to these edits, Figure 4 (Fig. 4) was moved to the end and became Fig. 6. All figures were improved in resolution and were placed as individual figures in the mentioned Zip folder, in case this could be more handy. We corrected some formatting errors in the bibliography. Please, find our detailed responses (in black) below, and locate the major edits in the MARKED MS by searching the indicated line numbers as “L XXX – XXX”. Compare the edited changes in the endorsed MARKED version of our MS ("Revised Manuscript with Track Changes"), all in conjunction addressing the referees’ and editorial comments and suggestions (in blue), which are copied underneath these lines.
Reviewers/Editor comments:
Reviewer #1: The authors examined new sponge material collected in Vietnam and Indonesia and compared it with previous data using molecular and morphological features to determine the taxonomy of their sponges. The authors found three species belonging to the genus Cladocroce (Porifera, Demospongiae). Species delimitation models and phylogenetic approaches using three molecular markers (COI, 28S, and 18S-ITS1-5.8S-ITS2-28S) provided evidence that for Cladocroce burapha and Cladocroce pansinii sp. nov. and Cladocroce lamellata sp. nov., with the latter species being delimited by morphological data only.

The authors concluded that C. burapha overlaps in distribution with Cladocroce pansinii in Vietnam and with Cladocroce lamellata in Indonesia, and suggested that the paratype of Cladocroce burapha should be transferred to Cladocroce pansinii.
All these reasons explain the relevance of the paper by Marco Bertolino and co-authors submitted to "Journal of Marine Science and Engineering".
General scores.
The data presented by the authors are original and significant. The study is correctly designed and the authors used appropriate sampling methods. In general, statistical analyses are performed with good technical standards. The authors conducted careful work that may attract the attention of a wide range of specialists focused on poriferan taxonomy.
We thank the reviewer for considering our work as original and significant, and valuable enough to attract the attention of a wide range of specialists focused on poriferan taxonomy.
Recommendations.
Figure 1 is of low resolution and is difficult to understand. The authors should increase both the resolution and font size.
We increased the resolution of Fig. 1, but if we increase the font size, the positions of the stations are not precise; for that reason, we left the same font, but with the high resolution the numbers are clearer.
The authors should change “Tab. “ to “Table” when referring to corresponding tables.
“Tab. “ was replaced by “Table” in all instances, as suggested.
The resolution of Figure 4 needs to be increased.
We increased the resolution of Fig. 4
In the reference list, all the Latin names should be italicized.
Thank you for this observation we corrected the font accordingly.

Reviewer 2 Report
Comments and Suggestions for Authors
An excellent addition to sponge taxonomy, based on morphological and molecular evidence. Good descriptions, easy to read text, and a fair discussion about how we determine and understand diversity. Cladocroce sponges can be very difficult to determine, due to poor descriptions, and these authors have done an excellent job in rectifying prior issues in taxonomy. This region is rich in sponges, and detailed descriptions aid in our understanding of diversity and drivers.
Minor edits in introduction/discussion to be considered (text altered in red)
All figures: higher resolution needed for publication
For methods: were any permits needed for the fieldwork? Mention here if there were.

Reviewer 3 Report
Comments and Suggestions for Authors
Dear authors - this is a very interesting study and you have used morphology and molecular systematics to good effect to support the integrity of species and distinction between several new species of Cladocroce.
I do not find much wrong with the study except that the expression needs to be improved ( I do not have the time to do more than I have) and there is an inconsistency with the addition of Taxonomic authorities and dates. As a general rule of thumb, the first time a taxon is mentioned in the abstract and then in the Introduction, the taxonomic authority and date should always be added. The second and subsequent uses do not require this. That include all higher taxon as well.
It would be helpful to have a table that compared all the known species in one place, in terms of spiculation and live characters.
My other concern is that the morphological characterisations should be separated form the molecular investigations, and that the latter sections should be combined at the end. These sections are lengthy and very convoluted and confusing and I got quite lost.
I feel it would be best if all molecular research is highlighted in one place and clearly sets out to discuss one species at a time.
So: describe the morphology of each species and outline issues in the remarks sections. Then at the very end, bring to bear the molecular work to deal with the issues raised in the morphology.

Reviewer #3: Dear authors - this is a very interesting study and you have used morphology and molecular systematics to good effect to support the integrity of species and distinction between several new species of Cladocroce.
We thank the reviewer for the positive feed-back regarding our work, we feel satisfied about these observations.

Taxonomic authorities and dates were corrected in the text according to the indications raised by the reviewer.
It would be helpful to have a table that compared all the known species in one place, in terms of spiculation and live characters.
We have provided a table as proposed by the reviewer.
My other concern is that the morphological characterisations should be separated form the molecular investigations, and that the latter sections should be combined at the end. These sections are lengthy and very convoluted and confusing and I got quite lost.

We have modified the text as suggested, removing the molecular paragraphs for each species, and creating a general molecular taxonomy section after the morphological descriptions. See L 1147 – 1260.
Authors further integrated the suggested modifications in the PDF provided by Rev#3 file in our new MS version. We appreciated the proposed corrections.
we changed the hyphen with the En-dash for date and numbers as suggested by the referee.
L 202: we accepted the suggestions about strongyles’shape.
L 215: we accepted the suggestion
L 247: we added the general measurements as requested for all the species, a the beginning of the spicule descriptions.
