Abstract

In this paper, we provide new bioacoustic and distributional data on Bokermannohyla sapiranga, as well as additional comparative bioacoustic data on topotypes of B. pseudopseudis, and re-evaluate the differential diagnosis of the former species with respect to the latter. Head shapes (dorsal and lateral views) presented such variation that should not be used to differentially diagnose them as originally proposed. On the other hand, the presence of a dermal ridge along outer tarsi, and color patterns of the eyes and dorsal surface of hand/toe disks still represent diagnostic characters between both species. We also found differences in temporal (call duration; notes per call), spectral (dominant frequency; harmonics), and structural (pulsed/non-pulsed note structure) traits of their calls. Distribution of B. sapiranga is extended eastward (Paracatu), which corresponds to the first record for the State of Minas Gerais, whereas B. pseudopseudis distribution seems to be restricted to rocky montane field environments of northern Goias State.
