We describe two new species of poison frog from central and southern Peru that have been referred to as Ameerega picta, A. hahneli, or A. altamazonica throughout the past thirty years. Our phylogenies generated with genomic data provide strong support that the two new species are successive sisters to two described taxa, A. rubriventris and A. altamazonica, and collectively comprise the Ameerega rubriventris complex. The first new taxon, Ameerega panguana sp. nov., can be distinguished from all other Ameerega by its combination of a unique white venter and an advertisement call of 1–2 notes per second. The second new taxon, Ameerega imasmari sp. nov., is the only cryptically colored Ameerega species that is disttributed across the Fitzcarrald Arch in Southern Peru which possesses a ‘peep’ advertisement call consisting of 3–4 notes per second and a dominant frequency of 4.3–4.5 kHz. Within the Ameerega rubriventris complex, we observed differences between species in their ventral coloration, tympanum diameter, and call, which suggest that these taxa are reproductively isolated from each other.

Calling activity, bioacoustics and the diet of males is reported for three different populations of Oophaga vicentei in central Panama. Calling activity was predicted by time of day, season and temperature with peaks between 08:00 h to 10:00 h and was more frequent during the dry season. Only at one location was calling activity positively correlated with air temperature. The temperature was also positively correlated with call repetition rates and negatively with call duration. Within the ten first calls of a call-bout, there was a cline variation in dominant frequency, call duration and silent intervals. The stomach contents of males comprised mainly insects but also a large number of oribatid mites.

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 Estação Ecológica Juami-Japurá, 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.

We conducted a molecular assessment of Colostethus-like frogs along an elevational gradient in the Serranía de Pirre, above Santa Cruz de Cana, eastern Panama, aiming to establish their species identity and to determine the altitudinal dis- tribution of C. latinasus. Our findings confirm the view of C. latinasus as an endemic species restricted to the highlands of this mountain range, i.e., 1350–1475 m.a.s.l., considered to be type locality of this species. We described the advertise- ment call of C. latinasus that consists of a series of 4–18 single, short and relatively loud “peep”-like notes given in rapid succession, and its spectral and temporal features were compared with calls of congeneric species. For the first time, DNA sequences from C. latinasus were obtained, since previously reported sequences were based on misidentified specimens. This is particularly important because C. latinasus is the type species of Colostethus, a genus considered paraphyletic ac- cording to recent phylogenetic analyses based on molecular data.
