title: Morphological and acoustic characterization of Proceratophrys goyana (Lissamphibia: Anura: Odontophrynidae), with the description of a sympatric and related new species.
abstract: Proceratophrys goyana was until recently the only species of the genus described from central Brazil. In this paper we characterize the adult morphology and advertisement call of this species, based on data collected at its type-locality (Chapada dos Veadeiros, Goiás, Brazil). These new data allowed us to recognize a new species of Proceratophrys, sympatric to P. goyana, which is described herein. Proceratophrys goyana is mainly characterized by the male SVL = 38.8-46.5 mm; a well-developed and continuous pair of dorsal sagittal ridges; upper eyelids triangular; developed frontoparietal crests, delimiting a shallow depression between them; overall color pattern browned, with the symmetrical dorsal ridges bordered laterally by dark brown undulations. Proceratophrys rotundipalpebra sp. nov. is characterized by the male SVL = 30.4-39.3 mm; the pair of symmetrical dorsal ridges well-developed anteriorly and somewhat interrupted in the sacral region; upper eyelids short and rounded; frontoparietal crests not well-developed; overall color pattern stained by 3-4 tonalities of gray, without a clear background color. The advertisement calls of both species are emitted in a multi-note pattern, each note pulsed, the first and last notes differing from each other and from those amidst the call in temporal features. The description of this new species is another example of the underestimated diversity of Proceratophrys in the Cerrado of central Brazil.
