Abstract
We describe a new species of the Bokermannohyla circumdata group from the Estação de Pesquisa e Desenvolvimento Ambi-ental Galheiro (EPDA-Galheiro) (19o 12′S; 47o 08′W), Municipality of Perdizes, State of Minas Gerais, a mid-altitudinal (~ 850m above sea level) riparian forest environment in the Cerrado of southeastern Brazil. Bokermannohyla napolii sp. nov. is alliedto 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 differentiatedfrom the former by having distal subarticular tubercle of finger III bifid/divided in males, and finger IV bifid/divided in malesand females; and from both B. luctuosa and B. circumdata by a distinctive advertisement call structure. We also provide bioa-coustic 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.References
