A reappraisal of the geographic distribution of Bokermannohyla sazimai (Anura: Hylidae) through morphological and bioacoustic approaches

Abstract

A reappraisal of the geographic distribution of Bokermannohyla sazimai (Anura: Hylidae) through morphological and bioacoustic approaches. The type locality of Bokermannohyla sazimai is in the Municipality of São Roque de Minas, State of Minas Gerais, Brazil. In this paper, we reassess the geographic distribution of B. sazimai and provide additional information on variation of several other non-topotypic populations in comparison with topotypic populations (São Roque de Minas and Vargem Bonita), on the basis of three lines of evidence(color pattern, morphometry, and vocalizations). Differences obtained among all populations with respect to color pattern, morphometry, and advertisement calls were attributed to interpopulational variation, so that this variation was not enough to recognize any population as a distinctive lineage in comparison with the topotypic information available on B. sazimai.
