The advertisement call of Physalaemus caete Pombal amp; Madureira, 1997 (Anura: Leptodactylidae: Leiuperinae), an endangered species endemic to Brazil's northern Atlantic Forest.

Foam-nesting frogs of the genus Physalaemus Fitzinger, 1826 have been long known for their diverse acoustic patterns (e.g., Barrio 1965; Bokermann 1966).

Unraveling the species diversity and relationships in the Leptodactylus mystaceus complex (Anura: Leptodactylidae), with the description of three new Brazilian species.

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 paper, we re-examine the monophyly, species diversity, and relationships in the L.

One step beyond a broad molecular phylogenetic analysis: Species delimitation of Adenomera marmorata Steindachner, 1867 (Anura: Leptodactylidae).

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 step of nomenclatural acts. Historically, the Neotropical frog genus Adenomera has been considered as a difficult taxonomic group because it comprises many morphologically similar species exhibiting high levels of intraspecific polymorphism.

A new species of Paratelmatobius (Anura: Leptodactylidae: Paratelmatobiinae) from the Atlantic Forest of southern Brazil.

A new species of Paratelmatobius is described from the Brazilian Atlantic Forest in the state of Paraná in southern Brazil. Adults, tadpoles, and vocalizations are described. Morphological traits and phylogenetic analysis place the new species within the P.

The vocalization of Gastrotheca fissipes (Boulenger, 1888) (Anura, Hemiphractidae) from the state of Pernambuco, northeastern Brazil.

Gastrotheca Fitzinger, 1843 (Hemiphractidae) is composed of 70 species classified into four species groups, among which Gastrotheca fissipes (Boulenger, 1882) and G. microdiscus (Andersson, 1910) species groups are distributed in the Brazilian Atlantic Forest (Castroviejo-Fisher et al. 2015; Duellman Venegas 2016).

The advertisement call of the Hoogmoed's harlequin toad Atelopus hoogmoedi Lescure, 1974 from northern Brazil (Anura, Bufonidae).

Harlequin toads (Atelopus) are distributed over a wide range in the Amazon Rainforest, mostly associated with streamlets in dense ombrophilous forests in lowland and sub-montane regions. Atelopus hoogmoedi Lescure, 1974a was considered as bearing full species status by Lötters et al. (2005), although until that moment this species had been assigned to a subspecies of A.

Advertisement calls, intraspecific variation and species diagnosis of six Brazilian species of Elachistocleis (Anura: Microhylidae: Gastrophryninae).

We describe for the first time the advertisement calls of three Elachistocleis species (E. surumu, E. magna, E.

Vocalizations, tadpole, and natural history of Crossodactylus werneri Pimenta, Cruz Caramaschi, 2014 (Anura: Hylodidae), with comments on distribution and intraspecific variation.

Crossodactylus werneri was described based on specimens collected in the 1970's at Parque Nacional do Itatiaia, being also reported for nearby localities. We collected specimens that we assigned to C. werneri, and recorded calls of the species during fieldworks at Serra das Cabras (Campinas, state of São Paulo).

A new species of Leptodactylus Fitzinger (Anura, Leptodactylidae, Leptodactylinae) from montane rock fields of the Chapada Diamantina, northeastern Brazil.

In this paper, we describe a new species of the Leptodactylusfuscus group on the basis of adult morphology and advertisement call, occurring restricted to montane rock fields of the Chapada Diamantina, northern portion of the Espinhaço Range, central State of Bahia, northeastern Brazil. In addition, we re-describe the advertisement call ofL. camaquara from its type locality.

Taxonomic circumscription of Adenomera martinezi (Bokermann, 1956) (Anura: Leptodactylidae: Leptodactylinae) with the recognition of a new cryptic taxon through a bioacoustic approach.

In this paper, we provide a taxonomic circumscription of Adenomera martinezi from its type locality (Cachimbo, southwestern State of Pará) since its description (57 years ago) based on a newly collected series of eleven adult topotypes, and through a bioacoustic approach, recognize an undescribed cryptic taxon under this nominal species, which is widely distributed in central and northern Brazil. Adenomera martinezi and Adenomera saci sp. nov.

Bioacoustics reveals two new syntopic species of Adenomera Steindachner (Anura: Leptodactylidae: Leptodactylinae) in the Cerrado of central Brazil.

In this paper, we describe two syntopic species of Adenomera from the Chapada dos Veadeiros microregion, northern State of Goiás, central Brazil, recognized based on morphology, color patterns, and bioacoustics. Specimens and calls were obtained in the Municipality of Teresina de Goiás, central Brazil. Adenomera cotuba sp.

New bioacoustic and distributional data on Bokermannohyla sapiranga Brandão et al., 2012 (Anura: Hylidae): revisiting its diagnosis in comparison with B. pseudopseudis (Miranda-Ribeiro, 1937).

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.

A new species of Pseudopaludicola Miranda-Ribeiro (Leiuperinae: Leptodactylidae: Anura) from the Cerrado of Southeastern Brazil.

A new species of Pseudopaludicola is described from the Cerrado of southeastern Brazil. Pseudopaludicola facureae sp. nov.
