Abstract

Recent studies have shown that species diversity of the South American frog genusDendropsophusis significantly underestimated, especially in Amazonia. Herein, through integrative taxonomy a new species ofDendropsophusfrom the east bank of the upper Madeira River, Brazil is described. Based on molecular phylogenetic and morphological analyses, the new species is referred to theD. microcephalusspecies group, where it is differentiated from its congeners mainly by having a green bilobate vocal sac and an advertisement call comprising 1–4 monophasic notes emitted with a dominant frequency of 8,979–9,606 Hz. Based on intensive sampling conducted in the study area over the last ten years, the new species is restricted to the east bank of the upper Madeira River, although its geographic range is expected to include Bolivian forests close to the type locality.
