Bioacoustic data of the recently described Boophis calcaratus (Anura: Mantellidae: Boophinae), a cryptic treefrog from Eastern Madagascar

Abstract

The recent systematic classification of Malagasy amphibians by Glaw & Vences (2006) proposed a new monophyletic Boophis subgenus (Sahona), that includes the species formerly ascribed to the B. tephraeomystax group. This subgenus contains ten described species (Vallan et al. 2009), which show a rather cryptic colouration, sometimes reminding tree corks and lichens, as it is the case of B. lichenoides, B. guibei, and possibly also in B. xerophilus (Andreone 2002; Glaw & Vences 2007).
