Bioacoustical data are useful for studying amphibians, especially their conservation, taxonomy, and evolution, among others. Of the 12 species of the clade, only and have no published information about their advertisement calls. We recorded four males of in its type locality at Parque Nacional do Itatiaia, south-eastern Brazil. We used a Roland R26 digital recorder with a Sennheiser ME-67 microphone and analysed the recordings using the Raven Pro 1.5 software. We recorded two different types of calls (call A and call B). Both were composed of one pulsed note and presented a slightly ascending-descending frequency modulation. Call A was more frequent, having durations between 0.042 and 0.093 s with the dominant frequency ranging from 3375.0 to 3937.5 Hz, and was composed of 11 to 21 pulses separated by intervals that were not fully silent. Call B had durations between 0.711 and 1.610 s, with dominant frequency from 3281.2 to 3750.0 Hz, and was composed of 11 to 29 pulses separated by fully silent intervals. Among the clade, the calls of are more similar to those of , , , and B.aff.beckeri. The calls of differ from these species in its lower dominant frequency. present a short, single-note call with a lower pulse period (call A) and a long call with higher pulse period (call B), which differ from the other species of the clade. The coefficients of variation for the various bioacoustical attributes were calculated within- and between-males and these have been discussed. We also report a fight event between two males of . This is the first report of a fight in members of the clade.
生物声学数据对于研究两栖动物很有用，尤其是在它们的保护、分类学和进化等方面。在该进化枝的12个物种中，只有[物种名称1]和[物种名称2]没有关于其求偶叫声的已发表信息。我们在巴西东南部伊塔蒂亚伊国家公园的模式产地记录了4只[物种名称3]雄性个体的叫声。我们使用了一台配备森海塞尔ME - 67麦克风的罗兰R26数字录音机，并使用Raven Pro 1.5软件对录音进行分析。我们记录到了两种不同类型的叫声（叫声A和叫声B）。两者都由一个脉冲音组成，并呈现出略微上升 - 下降的频率调制。叫声A更频繁，持续时间在0.042至0.093秒之间，主频范围为3375.0至3937.5赫兹，由11至21个脉冲组成，脉冲之间的间隔并非完全无声。叫声B的持续时间在0.711至1.610秒之间,主频为3281.2至3750.0赫兹，由11至29个脉冲组成，脉冲之间由完全无声的间隔隔开。在该进化枝中，[物种名称3]的叫声与[物种名称4]、[物种名称5]、[物种名称6]和贝氏[物种名称7]的叫声更为相似。[物种名称#]的叫声在主频较低方面与这些物种不同。[物种名称3]呈现出一种短的、单音的叫声，脉冲周期较短（叫声A），以及一种长的、脉冲周期较长的叫声（叫声B），这与该进化枝的其他物种不同。我们计算了不同生物声学属性在雄性个体内部和之间的变异系数，并进行了讨论。我们还报告了两只[物种名称3]雄性个体之间的争斗事件。这是该进化枝成员间争斗的首次报道。
