| abstract | The aim of this paper is to propose a new species of Paralamellobates, P. argentinensis sp. nov., on the basis of adult stages and to redescribe Lamellobates quadricornis Pérez-Iñigo & Baggio, 1985. Based on a morphological comparison between Paralamellobates species and L. quadricornis, Paralamellobates quadricornis stat. nov., is proposed. |
