Cornops aquaticum

The data are those published by Romero et al. (2014). However, in that work and in this presentation, the results were compared with those of the morphometric study by Adis et al. (2007) in a wider study on a South American scale. These results were not aimed at dealing with Bergmann’s or Rensch’s rules (Adis et al. 2007) (according to Rensch’s rule, sexual dimorphism decreases when body size increases). Therefore, in Romero et al. (2014) we added these results to ours and compared them in order to ascertain whether they were in keeping with Rensch’s rule. In the present paper, we deal with Bergmann’s rule. As in Romero et al. (2014), only tegmen length was measured in the same way as in Adis et al. (2007). Therefore, we chose only this variable for this study.
