We report for the first time the occurrences in Brazil of Boana hobbsi, Osteocephalus deridens and Tepuihyla shushupe (Hylidae), and confirm the occurrences of Ranitomeya defleri and Ranitomeya variabilis (Dendrobatidae) referring voucher specimens obtained from an expedition to Esta\ç\ão Ecol\ógica Juami-Japur\á, state of Amazonas, Brazil, in February 2017. Additionally, we provide data on morphology of voucher specimens, advertisement calls, field observations and geographic distribution of these species. We also describe the external morphology of the female R. defleri, which was previously unknown to science.

Nyctimantis rugiceps Boulenger, 1882 (Fig. 1A) is a Neotropical treefrog (Duellman \& Trueb 1976; Faivovich et al. 2005) known only from disjunct localities in Amazonian Colombia, Ecuador, and Peru (P\érez-Villota et al. 2009). This species has the skin of the skull co-ossified and reproduces\—including calling behavior, egg deposition and tadpole development\—in water-filled tree or bamboo cavities (Duellman \& Trueb 1976; Duellman 1978). Given its secretive behavior, this is a poorly known species and, as noted by Duellman (1978: 169), \“the major clue to the life history of Nyctimantis is the calling behavior of the males\”. Unfortunately, the only quantitative description of the advertisement call of N. rugiceps is a brief passage in Duellman (1978) based on four specimens from Santa Cecilia, Ecuador, where important variables are missing (e.g., call duration). More importantly, graphs illustrating the waveform and spectrogram are missing. Considering these limitations and the importance of advertisement calls to the study of anurans (K\öhler et al. 2017), we provide a quantitative description using a call recording obtained in Leticia, Amazonas, Colombia.

Anurans emit advertisement calls with the purpose of attracting mates and repelling conspecific competitors. The evolution of call traits is expected to be associated with the evolution of anatomical and behavioral traits due to the physics of call emission and transmission. Additionally, since vocalizing might imply a trade-off with investment in parental care, the evolution of calls is expected to trade-off with parental care. Here, we investigated the association between body size, calling site, parental care and call properties (call duration, number of notes, peak frequency, frequency bandwidth and call structure) of the advertisement calls of glassfrogs (Centrolenidae)\—a family of Neotropical, leaf-dwelling anurans\—using phylogenetic comparative methods. We also explored the tempo and mode of evolution of these traits and compared them with those of three morphological traits associated with body size, locomotion and feeding. We generated and compiled acoustic data for 72 glassfrog species (46\% of total species richness), including representatives of all genera. We found that almost all acoustic traits have significant, but generally modest, phylogenetic signal. Peak frequency of calls is significantly associated with body-size, while call structure is significantly associated with calling site and paternal care. Thus, the evolution of body size and calling site could constrain call evolution. The estimated disparity of acoustic traits was larger than that of morphological traits and the peak in disparity of acoustic traits generally occurred later in the evolution of glassfrogs, indicating a historically recent outset of the acoustic divergence in this clade.
