Posição taxonômica de populações de Rhinella (Anura: Bufonidae) do grupo de R. marina (Linnaeus, 1758) com base em canto

Abstract

The 10 species Rhinella marina’s group (Anura, Bufonidae) are distributed in North America (Texas), Central America and throughout South America. In order to present a characterization of the advertisement call of the species Rhinella marina and Rhinella diptycha and a taxonomic position of four populations in the states of Minas Gerais, Rondônia, Pará and Amapá, we analyzed original and literature calls. We observed that the population of Rondônia and Minas Gerais presented similarities between themselves, as between Amazonas Leste (Pará and Amapá) mainly in the variables dominant frequency, note rate, pulses per note and note duration. Cocroft et. al. (2001) recorded at Manaus, Brazil, three important variables (number of notes per corner, duration and note interval) for R. marina that close to our Amazonas Leste analyses. Our data from Rhinella diptycha (Minas Gerais and Rondônia) resemble Kohler et. al. (1990) in the vocalizing duration, note duration and dominant frequency. In addition, we suggest a review of the article describing the new specie Rhinella diptcyha (Garda, 2010), previously called Rhinella Jimi, due to the great similarity between literary and those analyzed data for Amazonas Leste (spp. R. marina).
