A new species of the Bokermannohyla circumdata group (Anura: Hylidae) from southeastern Brazil, with bioacoustic data on seven species of the genus

We describe a new species of the Bokermannohyla circumdata group from the Estacao de Pesquisa e Desenvolvimento Ambiental Galheiro (EPDA-Galheiro) (19 degrees 12'S; 47 degrees 08'W), Municipality of Perdizes, State of Minas Gerais, a mid-altitudinal (similar or equal to 850 m above sea level) riparian forest environment in the Cerrado of southeastern Brazil. Bokermannohyla napolii sp. nov. is allied to the large-sized species of the group, diagnosed on the basis of adult morphology/morphometrics, and mainly vocalizations. Adult specimens of the new species are most closely related to those of B. luctuosa and B. circumdata, but can be differentiated from the former by having distal subarticular tubercle of finger III bifid/divided in males, and finger IV bifid/divided in males and females; and from both B. luctuosa and B. circumdata by a distinctive advertisement call structure. We also provide bioacoustic data on seven other species of the genus, including previously unknown advertisement calls of B. circumdata and B. carvalhoi, and re-description of the advertisement calls of B. luctuosa, B. ibitiguara, B. nanuzae, B. sazimai, and B. hylax.
