Reviewer 2 Report
The authors present the describing new species of Spelaeometra from a hotspot of troglobites in Brazil, Serra do Ramalho karst area, as the second species of this genus. This is a nice paper and I have no serious criticisms regarding methodology, results, and interpretation of results. The morphological descriptions are very concise and well-explanatory, and the photographs and illustrations are elaborate and aid in species identification. The literatures were well-surveyed. Only a few corrections concerning morphological terms are found, which are concerning the description part. Please check the PDF reviewed in detail.

Reviewer 3 Report
The paper describes a new troglobiont water measurer from Brazil and adds thereby to the knowledge of this particular inhabitants to limestone cages, so far unknown from similar habitats in other parts of the world, and once again places Brazil as the center for diversification of the Hydrometridae. The paper is very well written and includes not only description of the apterous male and female, and a comparison with the congener, Spelaeometra gruta, but does also include ecological observations of the habitat. One could wish for a better comparison of the two species of Spelaeometra in which the diagnostic features of both types are not just compared in text but with actual pictures and drawings, but the illustrations in both papers are fortunately excellent and allows such comparisons easily.
Author Response
All of the reviewer's comments were positive and they did not ask for anything in particular. Therefore, there is no need for corrections, according to this reviewer.
