Introduction
In my current work, I am looking at the evolution of the anuran acoustic system through the characterization of the acoustic diversity in mating signals and the vocal apparatus of leptodactylid frogs, and also incorporating data on calling behavior and mechanics of vocal sound production. In parallel, I am also interested in documenting the biodiversity and the vocal repertoire of Neotropical frogs.

Article
In a recent contribution to the systematics of Leptodactylus Fitzinger, 1826 frogs endemic to the Brazilian campo rupestre (Carvalho et al. 2021), we revealed a genetically divergent lineage as an unnamed species distributed in the northern portion of the Espinhaço Mountain Range (EMR). The species was named and described as Leptodactylus avivoca i...
Article
The campo rupestre is a unique mountaintop ecosystem in eastern South America, recognised for its endemism and as ecological refugia for plant and animal taxa. Multiple clades of frogs are represented in the Brazilian campo rupestre. One such case is four species of the Leptodactylus fuscus group, three of which are endemic to specific mountain ran...

Vocal sounds occur in most anurans and are often emitted as simple and stereotyped acoustic signals. Some frog groups, however, have complex signals and others can produce distinctive acoustic structures, such as purely ultrasonic calls. Crossodactylodes is a genus of bromeligenous frogs that is understudied in many aspects. This genus has been his...

Full-text available
The outstanding species richness of Amazonia has fascinated biologists for centuries. However, the records of actual numbers and distribution of species forming its ecosystems are so incomplete that the understanding of the historical causes and regional determinants of this diversity remain speculative. Anuran clades have repeatedly been documente...
Article
A large proportion of the biodiversity of Amazonia, one of the most diverse rainforest areas in the world, is yet to be formally described. One such case is the Neotropical frog genus Adenomera. We here evaluate the species richness and historical biogeography of the Adenomera heyeri clade by integrating molecular phylogenetic and species delimitat...
Article
The Leptodactylus melanonotus species group is widely distributed across the Neotropics and contains 17 valid species. Here we reassess the taxonomic status of several taxa of the group, focusing mainly on the Amazonian L. petersii and both its junior synonyms (L. brevipes and L. intermedius), based on morphological, acoustic, cytogenetic, and DNA...
Article
We describe a new species of the South American frog genus Adenomera, based on external morphology, color patterns, advertisement call, and mtDNA sequences. The new species was collected from the Japurá River basin in northwestern Brazilian Amazonia and is distinguished from all congeners by the combination of large snout–vent length (SVL), toe tip...

The Leptodactylus latrans species group currently comprises eight medium-to large-sized frog species with a convoluted taxonomic history, particularly related to the specific limits of the L. latrans complex, and the species pair Leptodactylus chaquensis-Leptodactylus macrosternum. Their homogeneous external morphology and continental geographic di...
Article
During recent field expeditions to an Amazonian region in eastern Guiana Shield (Serra do Navio, state of Amapá, northern Brazil), we collected and recorded calls of a species of Adelophryne, a diminutive leaf-litter-dwelling, direct- developing frog genus. After a careful integrative taxonomic evaluation using morphological, molecular, and bioacou...

Many aspects of the Amazonian amphibian fauna are yet under-studied. This is the case of the Amapá treefrog, Boana dentei, which was described in the 1960s based on a single female specimen from Serra do Navio, a Brazilian region of lowland Amazonian forests in the easternmost portion of the Guiana Shield. The species has been reported only a few t...
Article
Foam-nesting frogs of the genus Physalaemus Fitzinger, 1826 have been long known for their diverse acoustic patterns (e.g., Barrio 1965; Bokermann 1966). Of the 49 species, the vocalizations of only three remain unknown to date (see Table 1 of Hepp & Pombal 2020): P. caete Pombal & Madureira, 1997, P. deimaticus Sazima & Caramaschi, 1988, and P. in...

Members of the Leptodactylus mystaceus species complex are widely distributed in forests and open formations of South America east of the Andes. Species of the complex are morphologically similar or indistinguishable among each other, but acoustic data have been the cornerstone for species discrimination across their geographic ranges. In this pape...

Full-text available
Taxonomists always have had intense discussions about how species should be delimited and recently many studies have used integrative approaches by combining molecular, morphological , and bioacoustic data. Although these studies are paramount for understanding species diversity, few of them actually formalize species delimitations to the final ste...
Article
Adenomera andreae and A. hylaedactyla are two widespread Amazonian frogs that have been traditionally distinguished from each other by the use of different habitats, toe tip development, and more recently through advertisement calls. Yet, taxonomic identification of these species has always been challenging. Herein we undertake a review of type spe...

Leptodactylid frogs are phenotypically diverse, widely distributed across the Neotropics, and are known to harbor high levels of cryptic species diversity. This is especially true in Adenomera, where several candidate species have been recognized in a genetics-based study. Here we describe a new Amazonian species of Adenomera, which corresponds to...
